fsck.zfs - Dummy ZFS filesystem checker.
fsck.zfs [options] <dataset>
fsck.zfs is a shell stub that does nothing and always returns true. It is
installed by ZoL because some Linux distributions expect a fsck helper for all
filesystems.
All
options and the
dataset are ignored.
ZFS datasets are checked by running
zpool scrub on the containing pool.
An individual ZFS dataset is never checked independently of its pool, which is
unlike a regular filesystem.
On some systems, if the
dataset is in a degraded pool, then it might be
appropriate for
fsck.zfs to return exit code 4 to indicate an
uncorrected filesystem error.
Similarly, if the
dataset is in a faulted pool and has a legacy
/etc/fstab record, then
fsck.zfs should return exit code 8 to indicate
a fatal operational error.
