Hi: After a power outage, my server refuses to mount a BTRFS file system.
This is the result of trying to mount with options recovery,ro: BTRFS info (device sdc1): use lzo compression, level 0 BTRFS warning (device sdc1): 'recovery' is deprecated, use 'usebackuproot' instead BTRFS info (device sdc1): trying to use backup root at mount time BTRFS info (device sdc1): disk space caching is enabled BTRFS info (device sdc1): has skinny extents BTRFS error (device sdc1): super_total_bytes 6010266660864 mismatch with fs_devices total_rw_bytes 6010266663424 BTRFS error (device sdc1): failed to read chunk tree: -22 BTRFS error (device sdc1): open_ctree failed And this is the initial output of a "btrfs check --readonly": https://pastebin.com/6gs7hJTG I'm planning to do a "btrfs recover fix-device-size" but I don't know if it can be dangerous or if it's better to do a "btrfs check --repair" before. Any recommendation? Greets and thanks in advance. Rafael J. Alcántara Pérez. --
