btrfs rescue

Try to recover a damaged btrfs filesystem.

More information.

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
