| .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. |
