Hi,
I have a home dir btrfs on top of luks
Just recently there was a power falure to the machine and since then the volume is not mountable
1) I tried ro,recovery,nospace_cache,nospace_cache option of mount
2) I tried btrfs-zero-log -y -v
3) btrfsck --repair --init-csum-tree
But for sure there is data in the volume.
