.Sh DESCRIPTION
|
|
|
|
|
.Nm
|
|
|
|
|
is a thin shell wrapper that at most checks the status of a dataset's container pool.
|
|
|
|
|
It is installed by OpenZFS because some Linux
|
2021-03-31 20:49:56 +03:00
|
|
|
distributions expect a fsck helper for all filesystems.
|
2021-05-26 15:34:00 +03:00
|
|
|
.Pp
|
|
|
|
|
If more than one
|
|
|
|
|
.Ar dataset
|
|
|
|
|
is specified, each is checked in turn and the results binary-ored.
|
|
|
|
|
.
|
|
|

.Sh OPTIONS

|
Ignored.
|
|
|
|
|
.
|
|
|
|
|
.Sh NOTES
|
|
|
|
|
ZFS datasets are checked by running
|
|
|
|
|
.Nm zpool Cm scrub
|
|
|
|
|
on the containing pool.
|
|
|
|
|
An individual ZFS dataset is never checked independently of its pool,
|
|
|
|
|
which is unlike a regular filesystem.
|
|
|
|
|
.Pp
|
2021-03-31 20:49:56 +03:00
|
|
|
However, the
|
2021-05-26 15:34:00 +03:00
|
|
|
.Xr fsck 8
|
|
|
|
|
interface still allows it to communicate some errors: if the
|
|
|
|
|
.Ar dataset
|
|
|
|
|
is in a degraded pool, then
|
|
|
|
|
.Nm
|
2021-06-04 23:08:50 +03:00
|
|
|
will return exit code
|
|
|
|
|
.Sy 4
|
|
|
|
|
to indicate an uncorrected filesystem error.
|
2021-05-26 15:34:00 +03:00
|
|
|
.Pp
|
|
|
|
|
Similarly, if the
|
|
|
|
|
.Ar dataset
|
|
|
|
|
is in a faulted pool and has a legacy
|
|
|
|
|
.Pa /etc/fstab
|
|
|
|
|
record, then
|
|
|
|
|
.Nm
|
2021-06-04 23:08:50 +03:00
|
|
|
will return exit code
|
|
|
|
|
.Sy 8
|
|
|
|
|
to indicate a fatal operational error.
