QUOTACHECK(8)

NAME
quotacheck - filesystem quota consistency checker

SYNOPSIS
quotacheck [-g] [-u] [-v] filesystem file ...
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 following options are available:

-a  If 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.

-g  Only group quotas listed in /etc/fstab are to be checked.

-u  Only user quotas listed in /etc/fstab are to be checked.

-v  Quotacheck reports discrepancies between the calculated and recorded disk quotas and other additional diagnostic messages.

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. The rc startup procedure is controlled by the /etc/rc.conf variable check_quotas. Note that to enable this functionality in /etc/rc you also need to enable startup quota procedures with the variable enable_quotas in /etc/rc.conf.

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.

FILES
quota.user
    at the filesystem root with user quotas
quota.group
    at the filesystem root with group quotas
/etc/fstab
    default filesystems
