| fsck.btrfs(8) |
| ============= |
| |
| NAME |
| ---- |
| fsck.btrfs - do nothing, successfully |
| |
| SYNOPSIS |
| -------- |
| *fsck.btrfs* [-aApy] [<device>...] |
| |
| DESCRIPTION |
| ----------- |
| *fsck.btrfs* is a type of utility that should exist for any filesystem and is |
| called during system setup when the corresponding `/etc/fstab` entries |
| contain non-zero value for `fs_passno` , see `fstab`(5) for more. |
| |
| Traditional filesystems need to run their respective fsck utility in case the |
| filesystem was not unmounted cleanly and the log needs to be replayed before |
| mount. This is not needed for BTRFS. You should set fs_passno to 0. |
| |
| If you wish to check the consistency of a BTRFS filesystem or repair a damaged |
| filesystem, see `btrfs-check`(8). By default the filesystem |
| consistency is checked, the repair mode is enabled via '--repair' option (use |
| with care!). |
| |
| OPTIONS |
| ------- |
| The options are all the same and detect if *fsck.btrfs* is executed in |
| non-interactive mode and exits with success, |
| otherwise prints a message about btrfs check. |
| |
| EXIT STATUS |
| ----------- |
| There are two possible exit code returned: |
| |
| 0:: |
| No error |
| |
| 8:: |
| Operational error, eg. device does not exist |
| |
