Hello! I need some tips on how to repair the btrfs partition, following
repeated power outages from home.
The situation: For several months I have stopped using xpenology in
favor of another dedicated Linux distribution for network storage (at
another location I ran into the same btrfs corruption issue, but then I
didn't have much data on the server and I didn't shake my head. in
solving the problem). Now being the NAS server on which all the family
documents can be found. On it are installed 3 hdds: one of 2 Tb and 2 of
1 Gb configured in raid1 since using xpenology. The tried commands were:
btrfs scrub start /srv/dev-disk-by-label-2018.05.11-19-05-54 \ v15266 /
btrfs scrub status -dR /srv/dev-disk-by-label-2018.05.11-19-05-54 \ v15266 /
And
btrfs check --check-data-csum / dev / md126

What is more surprising to me is, that partition configured with raid1
btrfs have been corrupted from those power outages.
Thank you for your attention
