[Lustre-discuss] Deactivate OST

[Frank Heckes]

Hi all,

sorry if this has been answered before, but I could find only one
un-answered question concerning this topic in the archive.

Question is for lustre 1.8.1.

If I like to deactivate write operation for an OST temporary, but allow
clients to read still data from the OST, disabling the OST on the MDS
will do the job as described in the admin guide.

In case an OST was lost and clients shouldn't contact the OST anymore
(if OST is damaged irreversible) even for read operation, could I
execute the 'lcl --device <id> deactivate' command also on the clients?
Or is this action superfluous since the client will receive EIO's
anyway?
Many thanks in advance.
