Ok, here's a good one... I have a lustre set up with version 1.8. Its has a combo mdt/mgs on one machine and three OSSs with a couple of OSTs on each.
The array that the mdt/mgs was on died and decided to stay dead, taking its data with it. But, I thought, no problem I have my file level backup that I did a couple of days ago. But owing to a typo in the script I ran, I only got the tar and getfattr of the ROOT directory, rather than the whole volume. My question to the lustre public is.. is it possible to recover the data on the OSTs using this? If so, can anyone lend any pointers? (If, in theory its not possible, I'll stop banging my head against the wall and move on) Any advice appreciated!
