I was wondering because while looking at the man page for mkfs.lustre I saw the below \
option:

       --replace
              Used  to  initialize a target with the same --index as a previously \
used target if the old target was permanently lost for some reason (e.g. multiple \
                disk failure or massive corruption).  This avoids
              having the target try to register as a new target with the MGS.

w/r,
Kurt

I know you'd need to keep the config files, directory structures, etc.  How much of \
that info you need to keep around, I'm not 100% sure.

To get the MGS to accept it again, you may have to unmount and run tunefs.lustre \
--writeconf on all the targets.

Hello,

   I had a quick question about recreating osts... If I drain all the files off an \
ost can I just reformat it and have it added back into lustre, in essence reusing the \
same index?  The server wouldn't change.  Or would I have to preserve its \
configuration files?

w/r,
Kurt
