NAME
quotacheck
- filesystem quota consistency checker
SYNOPSIS
quotacheck
[-gquv]
filesystem ...
quotacheck
[-gquv]
[-l maxparallel]
-a
DESCRIPTION
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.
Available options:
- -a
-
If the
-a
flag is supplied in place of any filesystem names,
quotacheck
will check all the filesystems indicated in
/etc/fstab
to be read-write with disk quotas.
By default only the types of quotas listed in
/etc/fstab
are checked.
See also
-l.
- -g
-
Only group quotas listed in
/etc/fstab
are to be checked.
See also
-u.
- -l 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 given, the disks are checked round-robin,
one file system at a time.
This option is only valid with
-a.
- -q
-
quotacheck
runs more quickly,
particularly on systems with sparse user id usage,
but fails to correct quotas for users [groups]
not in the system user [group] database,
and owning no files on the filesystem,
if the quota file incorrectly believes that they do.
- -u
-
Only user quotas listed in
/etc/fstab
are to be checked.
See also
-g.
- -v
-
quotacheck
is more verbose,
and reports corrected discrepancies between the
calculated and recorded disk quotas.
Specifying both
-g
and
-u
is equivalent to the default.
Parallel passes are run on the filesystems required,
using the pass numbers in
/etc/fstab
in an identical fashion to
fsck(8).
Normally
quotacheck
operates silently.
quotacheck
expects each filesystem to be checked to have a
quota files named
quota.user
and
quota.group
which are located at the root of the associated file system.
These defaults may be overridden in
/etc/fstab
.
If a file is not present,
quotacheck
will create it.
quotacheck
is normally run at boot time from the
/etc/rc
file, see
rc(8),
before enabling disk quotas with
quotaon(8).
quotacheck
accesses the raw device in calculating the actual
disk usage for each user.
Thus, the filesystems
checked should be quiescent while
quotacheck
is running.
If
quotacheck
receives a
SIGINFO
signal
(see the
status
argument for
stty(1)),
a line will be written to the standard error output indicating
the name of the device currently being checked and progress information.
FILES
quota.user
-
at the filesystem root with user quotas
quota.group
-
