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
- at the filesystem root with group quotas
- /etc/fstab
- default filesystems
