QUOTACHECK(8)QUOTACHECK(8)NAMEquotacheck - filesystem quota consistency checker
SYNOPSISquotacheck [ -g ] [ -u ] [ -v ] filesystem ...
quotacheck [ -g ] [ -u ] [ -v ] -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. The optional -g
flag specifies that only group quotas should be checked. The optional
-u flag specifies that only user quotas should be checked. Specifying
both -g and -u is equivalent to the default.
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. The optional -g flag specifies that only group
quotas listed in /etc/fstab should be checked. The optional -u flag
specifies that only user quotas listed in /etc/fstab should be checked.
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. If the -v option is supplied,
quotacheck will report discrepancies between the calculated and
recorded disk quotas.
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.local 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.
