Hi:
I just attempted a recover from a 6 device btrfs fs, but failed.
A bunch of data came back, but not the whole file…
The "device 6 is missing” (see below for transcript) sounds like btrfs restore can’t find the other disks.
Should I be using a UUID here somehow (didn’t see anything in the docs… but maybe)?
Thanks for any advice!
Brad
