.Sh DESCRIPTION
|
|
.Nm Quotacheck
|
|
examines each filesystem,
|
|
builds a table of current disk usage,
|
|
and compares this table against that recorded
|
|
in the disk quota file for the filesystem.
|
|
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 filesystem is checked).
|
|
By default both user and group quotas are checked.
|
|
.Pp
|
|
Available options:
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
If the
|
|
.Fl a
|
|
flag is supplied in place of any filesystem names,
|
|
.Nm quotacheck
|
|
will check all the filesystems 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
|
|
.Nm quotacheck
|
|
reports discrepancies between the
|
|
calculated and recorded disk quotas.
|
|
.El
|
|
.Pp
|
|
Specifying both
|
|
.Fl g
|
|
and
|
|
.Fl u
|
|
is equivalent to the default.
|
|
Parallel passes are run on the filesystems required,
|
|
using the pass numbers in
|
|
.Pa /etc/fstab
|
|
in an identical fashion to
|
|
.Xr fsck 8 .
|
|
.Pp
|
|
Normally
|
|
.Nm quotacheck
|
|
operates silently.
|
|
.Pp
|
|
.Nm Quotacheck
|
|
expects each filesystem 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 quotacheck
|
|
will create it.
|
|
.Pp
|
|
.Nm Quotacheck
|
|
is normally run at boot time from the
|
|
.Pa /etc/rc.local
|
|
file, see
|
|
.Xr rc 8 ,
|
|
before enabling disk quotas with
|
|
.Xr quotaon 8 .
|
|
.Pp
|
|
.Nm Quotacheck
|
|
accesses the raw device in calculating the actual
|
|
disk usage for each user.
|
|
Thus, the filesystems
|
|
checked should be quiescent while
|
|
.Nm quotacheck
|
|
is running.
