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
-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
-u

maxparallel-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
-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.

The quotacheck
command appeared in
