.TH FSCK.ZFS 8 "Aug 24, 2020" OpenZFS
|
||
|
|
|
||
|
|
.SH NAME
|
||
|
|
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.
