Yes 5 filesystems on 4 OSS:s and 2 MDS in active/passive failover. Some 100 TB of space in total. > What exactly are the steps that you use an OST for another filesystem? The steps ?

The deactivation part has already been done, on all parts. As this was a mistake, I simply want the presence of the ost/osc out, not ever showing up again. Now it's showing up as INACTIVE as a part of the filesystem I mistakingly added it to. As it seems, this can't be done. Or can it?
