bionic (8) fsck.zfs.8.gz

Provided by: zfsutils-linux_0.7.5-1ubuntu16.12_amd64 bug

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.
