## Abstract
|
||||
## Overview
|
||||
|
||||
This service provides an oCIS extension that wraps [reva](https://github.com/cs3org/reva/) and adds an opinionated configuration to it.
|
||||
The storage extension wraps [reva](https://github.com/cs3org/reva/) and adds an opinionated configuration to provide two core services for the oCIS platform:
|
||||
1. A [*Spaces Registry*]({{< ref "./spacesregistry.md" >}}) that acts as a dictionary for storage *Spaces* and their metadata
|
||||
2. A [*Spaces Provider*]({{< ref "./spacesprovider.md" >}}) that organizes *Resources* in storage *Spaces* and persists them in an underlying *Storage System*
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
The below diagram shows the oCIS services and the contained reva services within as dashed boxes. In general:
|
||||
1. A request comes in at the proxy and is authenticated using OIDC.
|
||||
2. It is forwarded to the oCIS frontend which handles ocs and ocdav requests by talking to the reva gateway using the CS3 API.
|
||||
3. The gateway acts as a facade to the actual CS3 services: storage providers, user providers, group providers and sharing providers.
|
||||
*Clients* will use the *Spaces Registry* to poll or get notified about changes in all *Spaces* a user has access to. Every *Space* has a dedicated `/dav/spaces/<spaceid>` WebDAV endpoint that is served by a *Spaces Provider* which uses a specific reva storage driver to wrap an underlying *Storage System*.

Some architectural changes still need to be clarified or changed. Maybe an ADR is in order for all of the below.
|
||||
|
||||
## Reva Gateway changes
|
||||
|
||||
## A dedicated shares storage provider
|
||||
|
||||
Currently, when a user accepts a share, a cs3 reference is created in the users `/home/shares` folder. This reference represents the mount point of a share and can be renamed, similar to the share jail in ownCloud 10. This spreads the metadata of a share in two places:
|
||||
- the share is persisted in the *share manager*
|
||||
- the mount point of a share is persisted in the home *storage provider*
|
||||
|
||||
Furthermore, the *gateway* treats `/home/shares` different than any other path: it will stat all children and calculate an etag to allow clients to discover changes in accepted shares. This requires the storage provider to cooperate and provide this special `/shares` folder in the root of a users home when it is accessed as a home storage. That is the origin of the `enable_home` config flag that needs to be implemented for every storage driver.
|
||||
|
||||
In order to have a single source of truth we need to make the *share manager* aware of the mount point. We can then move all the logic that aggregates the etag in the share folder to a dedicated *shares storage provider* that is using the *share manager* for persistence. The *shares storage provider* would provide a `/shares` namespace outside of `/home` that lists all accepted shares for the current user. As a result the storage drivers no longer need to have a `enable_home` flag that jails users into their home. The `/home/shares` folder would move outside of the `/home`. In fact `/home` will no longer be needed, because the home folder concept can be implemented as a space: `CreateHome` would create a `personal` space on the.

||||
|
||||
{{< hint warning >}}
|
||||
What about copy pasting links from the browser? Well this storage is only really needed to have a path to ocm shares that actually reside on other instances. In the UI the shares would be listed by querying a *share manager*. It returns ResourceIds, which can be stated to fetch a path that is then accessible in the CS3 global namespace. Two caveats:
|
||||
- This only works for resources that are actually hosted by the current instance. For those it would leak the parent path segments to a shared resource.
|
||||
- For accepted OCM shares there must be a path in the [*CS3 global namespace*]({{< ref "./namespaces.md#cs3-global-namespaces" >}}) that has to be the same for all users, otherwise they cannot copy and share those URLs.

### The gateway should be responsible for path transformations
|
||||
|
||||
Currently, storage providers are aware af their mount point, coupling them tightly with the gateway.

||||
|
||||
## URL escaped string representation of a CS3 reference
|
||||
|
||||
For the spaces concept we introduced the `/dav/spaces/` endpoint. It encodes a cs3 *reference* in a URL compatible way.
|
||||
1. We can separate the path using a `/`: `/dav/spaces/<spaceid>/<path>`
|
||||
2. The `spaceid` currently is a cs3 resourceid, consisting of `<storageid>` and `<opaqueid>`. Since the opaqueid might contain `/` eg. for the local driver we have to urlencode the spaceid.
|
||||
|
||||
To access resources by id we need to make the `/dav/meta/<resourceid>` able to list directories... Otherwise id based navigation first has to look up the path. Or we use the libregraph api for id based navigation.
|
||||
|
||||
A *reference* is a logical concept. It identifies a [*resource*]({{< ref "#resources" >}}) and consists of a `<resource_id>` and a `<path>`. A `<resource_id>` consists of a `<storage_id>` and a `<node_id>`. They can be concatenated using the separators `!` and `:`:
|
||||
```
|
||||
<storage_id>!<node_id>:<path>
|
||||
```
|
||||
While all components are optional, only three cases are used:
|
||||
| format | example | description |
|
||||
|-|-|-|
|
||||
| `!:<absolute_path>` | `!:/absolute/path/to/file.ext` | absolute path |
|
||||
| `<storage_space>!:<relative_path>` | `ee1687e5-ac7f-426d-a6c0-03fed91d5f62!:path/to/file.ext` | path relative to the root of the storage space |
|
||||
| `<storage_space>!<root>:<relative_path>` | `ee1687e5-ac7f-426d-a6c0-03fed91d5f62!c3cf23bb-8f47-4719-a150-1d25a1f6fb56:to/file.ext` | path relative to the specified node in the storage space, used to reference resources without disclosing parent paths |
|
||||
|
||||
`<storage_space>` should be a UUID to prevent references from breaking when a *user* or [*storage space*]({{< ref "#storage-spaces" >}}) gets renamed. But it can also be derived from a migration of an oc10 instance by concatenating an instance identifier and the numeric storage id from oc10, e.g. `oc10-instance-a$1234`.
|
||||
|
||||
A reference will often start as an absolute/global path, e.g. `!:/home/Projects/Foo`. The gateway will look up the storage provider that is responsible for the path
|
||||
|
||||
| Name | Description | Who resolves it? |
|
||||
|------|-------------|-|
|
||||
| `!:/home/Projects/Foo` | the absolute path a client like davfs will use. | The gateway uses the storage registry to look up the responsible storage provider |
|
||||
| `ee1687e5-ac7f-426d-a6c0-03fed91d5f62!:/Projects/Foo` | the `storage_space` is the same as the `root`, the path becomes relative to the root | the storage provider can use this reference to identify this resource |
|
||||
|
||||
Now, the same file is accessed as a share
|
||||
| Name | Description |
|
||||
|------|-------------|
|
||||
| `!:/users/Einstein/Projects/Foo` | `Foo` is the shared folder |
|
||||
| `ee1687e5-ac7f-426d-a6c0-03fed91d5f62!56f7ceca-e7f8-4530-9a7a-fe4b7ec8089a:` | `56f7ceca-e7f8-4530-9a7a-fe4b7ec8089a` is the id of `Foo`, the path is empty |
|
||||
|
||||
|
||||
The `:`, `!` and `$` are chosen from the set of [RFC3986 sub delimiters](https://tools.ietf.org/html/rfc3986#section-2.2) on purpose. They can be used in URLs without having to be encoded. In some cases, a delimiter can be left out if a component is not set:
|
||||
| reference | interpretation |
|
||||
|-|-|
|
||||
| `/absolute/path/to/file.ext` | absolute path, all delimiters omitted |
|
||||
| `ee1687e5-ac7f-426d-a6c0-03fed91d5f62!path/to/file.ext` | relative path in the given storage space, root delimiter `:` omitted |
|
||||
| `56f7ceca-e7f8-4530-9a7a-fe4b7ec8089a:to/file.ext` | relative path in the given root node, storage space delimiter `!` omitted |
|
||||
| `ee1687e5-ac7f-426d-a6c0-03fed91d5f62!56f7ceca-e7f8-4530-9a7a-fe4b7ec8089a:` | node id in the given storage space, `:` must be present |
|
||||
| `ee1687e5-ac7f-426d-a6c0-03fed91d5f62` | root of the storage space, all delimiters omitted, can be distinguished by the `/` |
|
||||
|
||||
## space providers
|
||||
When looking up an id based resource the reference must use a logical space id, not a CS3 resource id. Otherwise id based requests, which only have a resourceid consisting of a storage id and a node id cannot be routed to the correct storage provider if the storage has moved from one storage provider to another.
|
||||
|
||||
if the registry routes based on the storageid AND the nodeid it has to keep a cache of all nodeids in order to route all requests for a storage space (which consists of storage it + nodeid) to the correct storage provider. the correct resourceid for a node in a storage space would be `<storageid>$<rootnodeid>!<nodeid>`. The `<storageid>$<rootnodeid>` part allow the storage registry to route all id based requests to the correct storage provider. This becomes relevant when the storage space was moved from one storage provider to another. The storage space id remains the same, but the internal address and port change.
|
||||
|
||||
TODO discuss to clarify further
|
||||
|
||||
## Storage drivers
|
||||
|
||||
### allow clients to send a uuid on upload
|
||||
iOS clients can only queue single requests to be executed in the background. They queue an upload and need to be able to identify the uploaded file after it has been uploaded to the server. The disconnected nature of the connection might cause workflows or manual user interaction with the file on the server to move the file to a different place or changing the content while the device is offline. However, on the device users might have marked the file as favorite or added it to other iOS specific collections. To be able to reliably identify the file the client can generate a `uuid` and attach it to the file metadata during the upload. While it is not necessary to look up files by this `uuid` having a second file id that serves exactly the same purpose as the `file id` is redundant.
|
||||
|
||||
Another aspect for the `file id` / `uuid` is that it must be a logical identifier that can be set, at least by internal systems. Without a writeable fileid we cannot restore backups or migrate storage spaces from one storage provider to another storage provider.
|
||||
|
||||
Technically, this means that every storage driver needs to have a map of a `uuid` to an internal resource identifier. This internal resource identifier can be
|
||||
- an eos fileid, because eos can look up files by id
|
||||
- an inode if the filesystem and the storage driver support looking up by inode
|
||||
- a path if the storage driver has no way of looking up files by id.
|
||||
- In this case other mechanisms like inotify, kernel audit or a fuse overlay might be used to keep the paths up to date.
|
||||
- to prevent excessive writes when deep folders are renamed a reverse map might be used: it will map the `uuid` to `<parentuuid>:<childname>`, in order to trade writes for reads
|
||||
- as a fallback a sync job can read the file id from the metadata of the resources and populate the uuid to internal id map.
|
||||
|
||||
The TUS upload can take metadata, for PUT we might need a header.
|
||||
|
||||
### Space id vs resource id vs storage id
|
||||
|
||||
We have `/dav/meta/<fileid>` where the `fileid` is a string that was returned by a PROPFIND or by the `/graph/v1.0/me/drives/` endpoint? That returns a space id and the root drive item which has an `id`
|
||||
|
||||
Does that `id` have a specific format? We currently concatenate as `<storageid>!<nodeid>`.
|
||||
|
||||
A request against `/dav/meta/fileid` will use the reva storage registry to look up a path.
|
||||
|
||||
What if the storage space is moved to another storage provider. This happens during a migration:
|
||||
|
||||
1. the current oc10 fileids need to be prefixed with at least the numeric storage id to shard them.
|
||||
|
||||
`123` becomes `instanceprefix$345!123` if we use a custom prefix that identifies an instance (so we can merge multiple instances into one ocis instance) and append the numeric storageid `345`. The pattern is `<instanceprefix>$<numericstorageid>!<fileid>`.
|
||||
|
||||
Every `<instanceprefix>$<numericstorageid>` identifies a space.
|
||||
|
||||
- [ ] the owncloudsql driver can return these spaceids when listing spaces.
|
||||
|
||||
Why does it not work if we just use the fileid of the root node in the db?
|
||||
|
||||
Say we have a space with three resources:
|
||||
`<instanceprefix>$<numericstorageid>!<fileid>`
|
||||
`instanceprefix$345!1`
|
||||
`instanceprefix$345!2`
|
||||
`instanceprefix$345!3`
|
||||
|
||||
All users have moved to ocis and the registry contains a regex to route all `instanceprefix.*` references to the storageprovider with the owncloudsql driver. It is up to the driver to locate the correct resource by using the filecache table. In this case the numeric storage id is unnecessary.
|
||||
|
||||
Now we migrate the space `345` to another storage driver:
|
||||
- the storage registry contains a new entry for `instanceprefix$345` to send all resource ids for that space to the new storage provider
|
||||
- the new storage driver has to take into account the full storageid because the nodeid may only be unique per storage space.
|
||||
|
||||
If we now have to fetch the path on the `/dav/meta/` endpoint:
|
||||
`/dav/meta/instanceprefix$345!1`
|
||||
`/dav/meta/instanceprefix$345!2`
|
||||
`/dav/meta/instanceprefix$345!3`
|
||||
|
||||
This would work because the registry always sees `instanceprefix$345` as the storageid.
|
||||
|
||||
Now if we use the fileids directly and leave out the numeric storageid:
|
||||
`<instanceprefix>!<fileid>`
|
||||
`instanceprefix!1`
|
||||
`instanceprefix!2`
|
||||
`instanceprefix!3`
|
||||
|
||||
This is the current `<storageid>!<nodeid>` format.
|
||||
|
||||
The reva storage registry contains a `instanceid` entry pointing to the storage provider with the owncloudsql driver.
|
||||
|
||||
Resources can be looked up because the oc_filecache has a unique fileid over all storages.
|
||||
|
||||
Now we again migrate the space `345` to another storage driver:
|
||||
- the storage registry contains a new entry for `instanceprefix!1` so the storage space root now points to the new storage provider
|
||||
- The registry needs to be aware of node ids to route properly. This is a no go. We don't want to keep a cache of *all* nodeids in the registry. Only the root nodes of spaces.
|
||||
- The new storage driver only has a nodeid which might collide with other nodeids from other storage spaces, eg when two instances are imported into one ocis instance. Although it would be possible to just set up two storage providers extra care would have to be taken to prevent nodeid collisions when importing a space.
|
||||
|
||||
If we now have to fetch the path on the `/dav/meta/` endpoint:
|
||||
`/dav/meta/instanceprefix!1` would work because it is the root of a space
|
||||
`/dav/meta/instanceprefix!2` would cause the gateway to poll all storage providers because the registry has no way to determine the responsible storage provider
|
||||
`/dav/meta/instanceprefix!3` same
|
||||
|
||||
The problem is that without a part in the storageid that allows differentiating storage spaces we cannot route them individually.
|
||||
|
||||
Now, we could use the nodeid of the root of a storage space as the spaceid ... if it is a uuid. If it is numeric it needs a prefix to distinguish it from other spaces.
|
||||
`<space-root-uuid>!<fileid>` would be easy for the decomposedfs.
|
||||
eos might use numeric ids: `<eosprefix>$<space-root-fileid>!<fileid>`, but it needs a custom prefix to distinguish multiple eos instances.
|
||||
|
||||
Furthermore, when migrating spaces between storage providers we want to stay collision free, which is why we should recommend uuids.
|
||||
|
||||
All this has implications for the decomposedfs, because it needs to split the nodes per space to prevent them from colliding.

To release a new version of the storage submodule, you have to follow a few simple steps.
|
||||
|
||||
## Preparation
|
||||
|
||||
1. Before releasing, make sure that reva has been [updated to the desired version]({{< ref "updating" >}})
|
||||
|
||||
## Release
|
||||
1. Check out master
|
||||
{{< highlight txt >}}
|
||||
git checkout master
|
||||
git pull origin master
|
||||
{{< / highlight >}}
|

## Storage Spaces
|
||||
A storage *space* is a logical concept. It organizes a set of [*resources*]({{< ref "#resources" >}}) in a hierarchical tree. It has a single *owner* (*user* or *group*),
|
||||
a *quota*, *permissions* and is identified by a `storage space id`.
|
||||
|
||||
{{< svg src="extensions/storage/static/storagespace.drawio.svg" >}}
|
||||
|
||||
Examples would be every user's personal storage *space*, project storage *spaces* or group storage *spaces*. While they all serve different purposes and may or may not have workflows like anti virus scanning enabled, we need a way to identify and manage these subtrees in a generic way. By creating a dedicated concept for them this becomes easier and literally makes the codebase cleaner. A storage [*Spaces Registry*]({{< ref "./spacesregistry.md" >}}) then allows listing the capabilities of storage *spaces*, e.g. free space, quota, owner, syncable, root etag, upload workflow steps, ...
|
||||
|
||||
Finally, a logical `storage space id` is not tied to a specific [*spaces provider*]({{< ref "./spacesprovider.md" >}}). If the [*storage driver*]({{< ref "./storagedrivers.md" >}}) supports it, we can import existing files including their `file id`, which makes it possible to move storage *spaces* between [*spaces providers*]({{< ref "./spacesprovider.md" >}}) to implement storage classes, e.g. with or without archival, workflows, on SSDs or HDDs.
|
||||
|
||||
## Shares
|
||||
*To be clarified: we are aware that [*storage spaces*]({{< ref "#storage-spaces" >}}) may be too 'heavywheight' for ad hoc sharing with groups. That being said, there is no technical reason why group shares should not be treated like storage [*spaces*]({{< ref "#storage-spaces" >}}) that users can provision themselves. They would share the quota with the users home or personal storage [*space*]({{< ref "#storage-spaces" >}}) and the share initiator would be the sole owner. Technically, the mechanism of treating a share like a new storage [*space*]({{< ref "#storage-spaces" >}}) would be the same. This obviously also extends to user shares and even file individual shares that would be wrapped in a virtual collection. It would also become possible to share collections of arbitrary files in a single storage space, e.g. the ten best pictures from a large album.*

## Notes
|
||||
|
||||
We can implement [ListStorageSpaces](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.ListStorageSpacesRequest) by either
|
||||
- iterating over the root of the storage and treating every folder following the `<user_layout>` as a `home` *storage space*,
|
||||
- iterating over the root of the storage and treating every folder following a new `<project_layout>` as a `project` *storage space*, or
|
||||
- iterating over the root of the storage and treating every folder following a generic `<layout>` as a *storage space* for a configurable space type, or
|
||||
- we allow configuring a map of `space type` to `layout` (based on the [CreateStorageSpaceRequest](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.CreateStorageSpaceRequest)) which would allow things like
|
||||
```
|
||||

The correct endpoint for a users home [*storage space*]({{< ref "./terminology.md#storage-spaces" >}}) in oc10 is `remote.php/dav/files/<username>`. In oc10 All requests at this endpoint use a path based reference that is relative to the users home. In oCIS this can be configured and defaults to `/home` as well. Other API endpoints like ocs and the web UI still expect this to be the users home.

In oc10 we originally had `remote.php/webdav` which would render the current users home [*storage space*]({{< ref "./terminology.md#storage-spaces" >}}). The early versions (pre OC7) would jail all received shares into a `remote.php/webdav/shares` subfolder. The semantics for syncing such a folder are [not trivially predictable](https://github.com/owncloud/core/issues/5349), which is why we made shares [freely mountable](https://github.com/owncloud/core/pull/8026) anywhere in the users home.
|
||||
|
||||
The current reva implementation jails shares into a `remote.php/webdav/Shares` folder for performance reasons. Obviously, this brings back the [special semantics for syncing](https://github.com/owncloud/product/issues/7). In the future we will follow [a different solution](https://github.com/owncloud/product/issues/302) and jail the received shares into a dedicated `/shares` space, on the same level as `/home` and `/spaces`. We will add a dedicated [API to list all *storage spaces*](https://github.com/owncloud/ocis/pull/1827) a user has access to and where they are mounted in the users *namespace*.

An alternative would be to introduce a new `remote.php/dav/spaces` or `remote.php/dav/global` endpoint. However, `remote.php/dav` properly follows the WebDAV RFCs strictly. To ensure that all resources under that [*namespace*]({{< ref "./terminology.md#namespaces" >}}) are scoped to the user the URL would have to include the principal like `remote.php/dav/spaces/<username>`, a precondition for e.g. WebDAV [RFC5397](https://tools.ietf.org/html/rfc5397).

### User and Group provisioning
|
||||
|

In oc10 users are identified by a username, which cannot change, because it is used as a foreign key in several tables. For oCIS we are internally identifying users by a UUID, while using the username in the WebDAV and OCS APIs for backwards compatability. To distinguish this in the URLs we are using `<username>` instead of `<userid>`. You may have encountered `<userlayout>`, which refers to a template that can be configured to build several path segments by filling in user properties, e.g. the first character of the username (`{{substr 0 1 .Username}}/{{.Username}}`), the identity provider (`{{.Id.Idp}}/{{.Username}}`) or the email (`{{.Mail}}`)

|

Make no mistake, the [OCS Provisioning API](https://doc.owncloud.com/server/developer_manual/core/apis/provisioning-api.html) uses `userid` while it actually is the username, because it is what you use to login.

It is used by the reva *gateway*

to look up `address` and `port` of the [*storage provider*]({{< ref "#storage-providers" >}})

## Storage commands
|
||||
A *storage driver* implements access to a [*storage system*]({{< ref "#storage-systems" >}}):
|
||||
|
||||
`storage` has multiple storage provider commands to preconfigure different default configurations for the reva *storage provider* service. While you could rerun `storage storage-oc` multiple times with different flags to get multiple instances we are giving the different commands the necessary default configuration to allow the `ocis` binary to simply start them and not deal with configuration.
|
||||
It maps the *path* and *id* based CS3 *references* to an appropriate [*storage system*]({{< ref "#storage-systems" >}}) specific reference, e.g.:
|
||||
- eos file ids
|
||||
- posix inodes or paths

- deconstructed filesystem nodes

### OCIS and S3NG Storage Driver
|
||||
|
||||
The oCIS storage driver is the default storage driver. It decomposes the metadata and persists it in a POSIX filesystem. Blobs are stored on the filesystem as well. The layout makes extensive use of symlinks and extended attributes. A filesystem like xfs or zfs without inode size limitations is recommended. We will evolve this to further integrate with file systems like cephfs or gpfs.
|
||||
|
||||
The S3NG storage driver uses the same metadata layout on a POSIX storage as the oCIS driver, but it uses S3 as the blob storage.

Communication is hard. And clear communication is even harder. You may encounter the following terms throughout the documentation, in the code or when talking to other developers.

## Logical concepts
|
||||
|
||||
### Resources
|
||||
A *resource* is the basic building block that oCIS manages. It can be of [different types](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.ResourceType):
|
||||
- an actual *file*
|
||||
- a *container*, e.g. a folder or bucket
|
||||
- a *symlink*, or
|
||||
- a [*reference*]({{< ref "#references" >}}) which can point to a resource in another [*storage provider*]({{< ref "#storage-providers" >}})
|
||||
|
||||
### References
|
||||
A *reference* identifies a [*resource*]({{< ref "#resources" >}}). A [*CS3 reference*](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.Reference) can carry a *path* and a [CS3 *resource id*](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.ResourceId). The references come in two flavors: absolute and combined.
|
||||
Absolute references have either the *path* or the *resource id* set:
|
||||
- An absolute *path* MUST start with a `/`. The *resource id* MUST be empty.
|
||||
- An absolute *resource id* uniquely identifies a [*resource*]({{< ref "#resources" >}}) and is used as a stable identifier for sharing. The *path* MUST be empty.
|
||||
Combined references have both, *path* and *resource id* set:
|
||||
- the *resource id* identifies the root [*resource*]({{< ref "#resources" >}})
|
||||
- the *path* is relative to that root. It MUST start with `.`

## Gateways
|
||||
### Gateways
|
||||
A *gateway* acts as a facade to the storage related services. It authenticates and forwards API calls that are publicly accessible.
|
||||
|
||||
|
||||
{{< hint warning >}}
|
||||
**Proposed Change**
|
||||
Currently, the *gateway* treats `/home/shares` different than any other path: it will stat all children and calculate an etag to allow clients to discover changes in accepted shares. This requires the storage provider to cooperate and provide this special `/shares` folder in the root of a users home when it is accessed as a home storage, which is a config flag that needs to be set for every storage driver.
|
||||
|
||||
The `enable_home` flag will cause drivers to jail path based requests into a `<userlayout>` subfolder. In effect it divides a storage provider into multiple [*storage spaces*]({{< ref "#storage-spaces" >}}): when calling `CreateHome` a subfolder following the `<userlayout>` is created and market as the root of a users home. Both, the eos and ocis storage drivers use extended attributes to mark the folder as the end of the size aggregation and tree mtime propagation mechanism. Even setting the quota is possible like that. All this literally is a [*storage space*]({{< ref "#storage-spaces" >}}).
|
||||
|
||||
We can implement [ListStorageSpaces](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.ListStorageSpacesRequest) by either
|
||||
- iterating over the root of the storage and treating every folder following the `<userlayout>` as a `home` *storage space*,
|
||||
- iterating over the root of the storage and treating every folder following a new `<projectlayout>` as a `project` *storage space*, or
|
||||
- iterating over the root of the storage and treating every folder following a generic `<layout>` as a *storage space* for a configurable space type, or
|
||||
- we allow configuring a map of `space type` to `layout` (based on the [CreateStorageSpaceRequest](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.CreateStorageSpaceRequest)) which would allow things like
|
||||
```
|
||||
home=/var/lib/ocis/storage/home/{{substr 0 1 .Owner.Username}}/{{.Owner.Username}}
|
||||
spaces=/spaces/var/lib/ocis/storage/projects/{{.Name}}
|
||||
```
|
||||
|
||||
This would make the `GetHome()` call return the path to the *storage provider* including the relative path to the *storage space*. No need for a *storage provider* mounted at `/home`. This is just a UI alias for `/users/<userlayout>`. Just like a normal `/home/<username>` on a linux machine.
|
||||
|
||||
But if we have no `/home` where do we find the shares, and how can clients discover changes in accepted shares?
|
||||
|
||||
The `/shares` namespace should be provided by a *storage provider* that lists all accepted shares for the current user... but what about copy pasting links from the browser? Well this storage is only really needed to have a path to ocm shares that actually reside on other instances. In the UI the shares would be listed by querying a *share manager*. It returns ResourceIds, which can be stated to fetch a path that is then accessible in the CS3 global namespace. Two caveats:
|
||||
- This only works for resources that are actually hosted by the current instance. For those it would leak the parent path segments to a shared resource.
|
||||
- For accepted OCM shares there must be a path in the [*CS3 global namespace*]({{< ref "./namespaces.md#cs3-global-namespaces" >}}) that has to be the same for all users, otherwise they cannot copy and share those URLs.

### User and Group provisioning
|
||||
|
||||
In oc10 users are identified by a username, which cannot change, because it is used as a foreign key in several tables. For oCIS we are internally identifying users by a UUID, while using the username in the WebDAV and OCS APIs for backwards compatability. To distinguish this in the URLs we are using `<username>` instead of `<userid>`. You may have encountered `<user_layout>`, which refers to a template that can be configured to build several path segments by filling in user properties, e.g. the first character of the username (`{{substr 0 1 .Username}}/{{.Username}}`), the identity provider (`{{.Id.Idp}}/{{.Username}}`) or the email (`{{.Mail}}`)
|
||||
|
||||
{{< hint warning >}}
|
||||
Make no mistake, the [OCS Provisioning API](https://doc.owncloud.com/server/developer_manual/core/apis/provisioning-api.html) uses `userid` while it actually is the username, because it is what you use to login.

- [*Storage spaces*]({{< ref "../extensions/storage/terminology#storage-spaces" >}}) represent a collection of files and folders. A users personal files are a *storage space*, a group or project drive is a *storage space*, and even incoming shares are treated and implemented as *storage spaces*.

- [*Storage providers*]({{< ref "../extensions/storage/terminology#storage-providers" >}}) can hold multiple *storage spaces*.

To encourage users to switch you can promote the workspaces feature that is built into oCIS. The ownCloud 10 storage backend can be used for existing users. New users and group or project spaces can be provided by storage providers that better suit the underlying storage system.

#### Notes
|

Depending on the requirements and acceptable tradeoffs, a database less deployment using the ocis or s3ng storage driver is possible. There is also a [cephfs driver](https://github.com/cs3org/reva/pull/1209) on the way, that directly works on the API level instead of POSIX.

Profit! Well, on the one hand you do not need to maintain a clustered database setup and can rely on the storage system. On the other hand you are now in microservice wonderland and will have to relearn how to identify bottlenecks and scale oCIS accordingly. The good thing is that tools like jaeger and prometheus have evolved and will help you understand what is going on. But this is a different topic. See you on the other side!

The problem is that the username in owncloud 10 and in oCIS also need to be the same, which might not be the case when the ldap mapping used a different column. In that case we should add another owncloudusername attribute to the ldap server.
