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.

   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?
