[Lustre-discuss] Recovering a reformatted OST

[Bob Ball]

This is Lustre 2.1.6.

I did a dumb thing.  I reformatted a drained OST BEFORE I saved off 
appropriate data to re-establish it at its old index.  I don't know what 
I was thinking?  The files that I would normally restore are,
LAST_ID
last_rcvd
mountdata
umt3-OST0020

I know how to recreate the correct LAST_ID.  And, as this happened over 
a year ago on this same OST, I have old copies still of each of the 
others.  I know that "mountdata" is created when I created the lustre 
file system, so I would guess I can just continue to use that file.

My question, can I simply re-use these other, old file copies when I am 
ready to once again put a Lustre file system on this volume?

Thanks,
bob
