NAME

       fsck.zfs - Dummy ZFS filesystem checker.

SYNOPSIS

       fsck.zfs [options] <dataset>

DESCRIPTION

       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.

OPTIONS

       All options and the dataset are ignored.

NOTES

       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.

BUGS

       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.
