btrfs check

Check or repair a btrfs filesystem.

More information.

• Check a btrfs filesystem:

sudo btrfs check {path/to/partition}

• Check and repair a btrfs filesystem (dangerous):

sudo btrfs check --repair {path/to/partition}

• Show the progress of the check:

sudo btrfs check --progress {path/to/partition}

• Verify the checksum of each data block (if the filesystem is good):

sudo btrfs check --check-data-csum {path/to/partition}

• Use the `n`-th superblock (`n` can be 0, 1 or 2):

sudo btrfs check --super {n} {path/to/partition}

• Rebuild the checksum tree:

sudo btrfs check --repair --init-csum-tree {path/to/partition}

• Rebuild the extent tree:

sudo btrfs check --repair --init-extent-tree {path/to/partition}
