|
||||||
|
.Nm ""
|
||||||

|
||||||

|
||||||
|
.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
command invokes filesystem-specific programs to check
|
||||||
|
the special devices listed in the
|
||||||
|
.Xr fstab 5
|
||||||
|
file or in the command line for consistency.
|
||||||
|
.Pp
|
||||||
|
It is normally used in the script
|
||||||
|
.Pa /etc/rc
|
||||||
|
during automatic reboot.
|
||||||
|
If no filesystems are specified, and ``preen'' mode is enabled (
|
||||||
|
.Fl p
|
||||||
|
option)
|
||||||
|
.Nm
|
||||||
|
reads the table
|
||||||
|
.Pa /etc/fstab
|
||||||
|
to determine which filesystems to check.
|
||||||
|
Only partitions in fstab that are mounted ``rw,'' ``rq'' or ``ro''
|
||||||
|
and that have non-zero pass number are checked.
|
||||||
|
Filesystems with pass number 1 (normally just the root filesystem)
|
||||||
|
are checked one at a time.
|
||||||
|
When pass 1 completes, all remaining filesystems are checked,
|
||||||
|
running one process per disk drive.
|
||||||
|
The disk drive containing each filesystem is inferred from the longest prefix
|
||||||
|
of the device name that ends in a digit; the remaining characters are assumed
|
||||||
|
to be the partition designator.
|
||||||
|
.Pp
|
||||||
|
The options are as follows:
|
||||||
|
.Bl -tag -width indent
|
||||||
|
.It Fl d
|
||||||
|
Debugging mode. Just print the commands without executing them. Available
|
||||||
|
only if
|
||||||
|
.Nm
|
||||||
|
is compiled to support it.
|
||||||
|
.It Fl f
|
||||||
|
Force checking of filesystems, even when they are marked clean (for filesystems
|
||||||
|
that support this).
|
||||||
|
.It Fl l Ar maxparallel
|
||||||
|
Limit the number of parallel checks to the number specified in
|
||||||
|
the following argument. By default, the limit is the number of
|
||||||
|
disks, running one process per disk. If a smaller limit is giv-
|
||||||
|
en, the disks are checked round-robin, one filesystem at a time.
|
||||||
|
.It Fl n
|
||||||
|
Causes
|
||||||
|
.Nm
|
||||||
|
to assume no as the answer to all operator questions, except "CONTINUE?".
|
||||||
|
.It Fl p
|
||||||
|
Enter preen mode.
|
||||||
|
.It Fl t Ar fstype
|
||||||
|
Invoke
|
||||||
|
.Nm
|
||||||
|
only for the comma separated list of filesystem types. If the
|
||||||
|
list starts with
|
||||||
|
.Dq no
|
||||||
|
then invoke
|
||||||
|
.Nm
|
||||||
|
for the filesystem types that are not specified in the list.
|
||||||
|
.It Fl v
|
||||||
|
Print the commands before executing them.
|
||||||
|
.It Fl y
|
||||||
|
Causes
|
||||||
|
.Nm
|
||||||
|
to assume yes
|
||||||
|
as the answer to all operator questions.
|
||||||
|
.It Fl T Ar fstype:fsoptions
|
||||||
|
List of comma separated file system specific options for the specified
|
||||||
|
file system type, in the same format as
