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
read-write filesystems with an existing mount option file at its root. The
mount option file specifies the types of quotas that are to be
checked.-g-u-vquotacheck reports 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, in an identical fashion to
fsck(8).
Normally quotacheck operates silently.
Quotacheck expects each filesystem being
checked to have quota data files named .quota.user
and/or .quota.group located at the filesystem root.
If a binary data file is not present, quotacheck
will create it. The default filename and root location cannot be
overridden.
Quotacheck is normally run at
fsck time.
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.
Each of the following quota files is located at the root of the mounted filesystem. The mount option files are empty files whose existence indicates that quotas are to be enabled for that filesystem. The binary data files will be created by quotacheck, if they don't already exist.
quota(1), quotactl(2), edquota(8), fsck(8), quotaon(8), repquota(8)
The quotacheck command appeared in
4.2BSD.
