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
