.Sh DESCRIPTION
The
.Nm
utility examines each file system,
builds a table of current disk usage,
and compares this table against that recorded
in the disk quota file for the file system.
If any inconsistencies are detected, both the
quota file and the current system copy of the
incorrect quotas are updated (the latter only
occurs if an active file system is checked).
By default both user and group quotas are checked.
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl a
If supplied in place of any file system names,
.Nm
will check all the file systems indicated in
.Pa /etc/fstab
to be read-write with disk quotas.
By default only the types of quotas listed in
.Pa /etc/fstab
are checked.
.It Fl g
Only group quotas listed in
.Pa /etc/fstab
are to be checked.
.It Fl u
Only user quotas listed in
.Pa /etc/fstab
are to be checked.
.It Fl v
Report discrepancies between the
calculated and recorded disk quotas and other additional diagnostic messages.
.El
.Pp
Specifying both
.Fl g
and
.Fl u
is equivalent to the default.
Parallel passes are run on the file systems required,
using the pass numbers in
.Pa /etc/fstab
in an identical fashion to
.Xr fsck 8 .
.Pp
Normally,
.Nm
operates silently.
.Pp
The
.Nm
utility expects each file system to be checked to have a
quota files named
.Pa quota.user
and
.Pa quota.group
which are located at the root of the associated file system.
These defaults may be overridden in
.Pa /etc/fstab .
If a file is not present,
.Nm
will create it.
These files should be edited with the
.Xr edquota 8
utility.
.Pp
The
.Nm
utility is normally run at boot time from the
.Pa /etc/rc
file.
The rc startup procedure is controlled by the
.Pa /etc/rc.conf
variable
.Ar check_quotas .
Note that to enable this functionality in
.Pa /etc/rc
you also need to enable startup quota procedures
with the variable
.Ar enable_quotas
in
.Pa /etc/rc.conf .
.Pp
The
.Nm
utility accesses the raw device in calculating the actual
disk usage for each user.
Thus, the file systems
checked should be quiescent while
.Nm
is running.

Print out an informative message if the verbose option is given and an unknown uid/gid is found in the file system. This is useful if you wind up with a file in your file system that has a uid that is extremely large, since quotacheck will wind up running a very very long time due to it not handling large gaps in uids very well (this is a problem that should be addressed some day). Update the man page to reflect that fact the the -v flag now prints some additional diagnostic messages. 1996-02-21 18:40:54 +00:00			`calculated and recorded disk quotas and other additional diagnostic messages.`
