btrfs rescue

Try to recover a damaged btrfs filesystem. More information: https://btrfs.wiki.kernel.org/index.php/Manpage/btrfs-rescue.

  • Rebuild the filesystem metadata tree (very slow):

sudo btrfs rescue chunk-recover {{path/to/partition}}

  • Fix device size alignment related problems (e.g. unable to mount the filesystem with super total bytes mismatch):

sudo btrfs rescue fix-device-size {{path/to/partition}}

  • Recover a corrupted superblock from correct copies (recover the root of filesystem tree):

sudo btrfs rescue super-recover {{path/to/partition}}

  • Recover from an interrupted transactions (fixes log replay problems):

sudo btrfs rescue zero-log {{path/to/partition}}

  • Create a /dev/btrfs-control control device when mknod is not installed:

sudo btrfs rescue create-control-device
