|
> "stale file handle".

|
|
> The numeric value of this tunable is the number of seconds to cache file/directory name entries,
|
|
> where the default value of 330 indicates 5 1/2 minutes. There are two special values you may also set
|
|
> this to:
|
|
>
|
|
> * 0 which means, do not cache file/directory names at all, and
|
|
> * -1 which means cache file/directory names forever (or until array is stopped)
|
|
>
|
|
> A value of 0 would be appropriate if you are enabling NFS but only plan to use it for disk shares,
|
|
> not user shares.
|
|
>
|
|
> A value of -1 would be appropriate if no other timeout seems to solve the "stale file handle" on
|
|
> your client. Be aware that setting a value of -1 will cause the memory footprint to grow by approximatel
|
|
> 108 bytes per file/directory name cached. Depending how much RAM is installed in your server and how many
|
|
> files/directories you access via NFS this may or may not lead to out-of-memory conditions.
