.TH fsck.zfs 8 "2013 MAR 16" "ZFS on Linux" "System Administration Commands"
.SH NAME
.BR fsck.zfs " \- Dummy ZFS filesystem checker."
.SH SYNOPSIS
.LP
.BI "fsck.zfs [" "options" "] <" "dataset" ">"
.SH DESCRIPTION
.LP
\fBfsck.zfs\fR 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.
.SH OPTIONS
.HP
All \fIoptions\fR and the \fIdataset\fR are ignored.
.SH "NOTES"
.LP
ZFS datasets are checked by running \fBzpool scrub\fR on the
containing pool. An individual ZFS dataset is never checked
independently of its pool, which is unlike a regular filesystem.
.SH "BUGS"
.LP
On some systems, if the \fIdataset\fR is in a degraded pool, then it
might be appropriate for \fBfsck.zfs\fR to return exit code 4 to
indicate an uncorrected filesystem error.
.LP
Similarly, if the \fIdataset\fR is in a faulted pool and has a legacy
/etc/fstab record, then \fBfsck.zfs\fR should return exit code 8 to
indicate a fatal operational error.
