  27 .SH NAME
  28 fsck.zfs \- Dummy ZFS filesystem checker.
  29
  30 .SH SYNOPSIS
  31 .LP
  32 .BI "fsck.zfs [" "options" "] <" "dataset" ">"
  33
  34 .SH DESCRIPTION
  35 .LP
  36 \fBfsck.zfs\fR is a shell stub that does nothing and always returns
  37 true. It is installed by ZoL because some Linux distributions expect
  38 a fsck helper for all filesystems.
  39
  40 .SH OPTIONS
  41 .HP
  42 All \fIoptions\fR and the \fIdataset\fR are ignored.
  43
  44 .SH "NOTES"
  45 .LP
  46 ZFS datasets are checked by running \fBzpool scrub\fR on the
  47 containing pool. An individual ZFS dataset is never checked
  48 independently of its pool, which is unlike a regular filesystem.
  49
  50 .SH "BUGS"
  51 .LP
  52 On some systems, if the \fIdataset\fR is in a degraded pool, then it
  53 might be appropriate for \fBfsck.zfs\fR to return exit code 4 to
  54 indicate an uncorrected filesystem error.
  55 .LP
  56 Similarly, if the \fIdataset\fR is in a faulted pool and has a legacy
  57 /etc/fstab record, then \fBfsck.zfs\fR should return exit code 8 to
  58 indicate a fatal operational error.
