- Check a btrfs filesystem:
`sudo btrfs check {{path/to/partition}}`
`sudo btrfs {{[c|check]}} {{path/to/partition}}`
- Check and repair a btrfs filesystem (dangerous):
`sudo btrfs check --repair {{path/to/partition}}`
`sudo btrfs {{[c|check]}} --repair {{path/to/partition}}`
- Show the progress of the check:
`sudo btrfs check {{[-p|--progress]}} {{path/to/partition}}`
`sudo btrfs {{[c|check]}} {{[-p|--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}}`
`sudo btrfs {{[c|check]}} --check-data-csum {{path/to/partition}}`
- Use the `n`-th superblock (`n` can be 0, 1 or 2):
`sudo btrfs check {{[-s|--super]}} {{n}} {{path/to/partition}}`
`sudo btrfs {{[c|check]}} {{[-s|--super]}} {{n}} {{path/to/partition}}`
- Rebuild the checksum tree:
`sudo btrfs check --repair --init-csum-tree {{path/to/partition}}`
`sudo btrfs {{[c|check]}} --repair --init-csum-tree {{path/to/partition}}`
- Rebuild the extent tree:
`sudo btrfs check --repair --init-extent-tree {{path/to/partition}}`
`sudo btrfs {{[c|check]}} --repair --init-extent-tree {{path/to/partition}}`
