quotacheck —
file system quota consistency
checker
SYNOPSIS
quotacheck |
[-g] [-u]
[-v] filesystem
file ... |
quotacheck |
[-g] [-u]
[-v] -a |
DESCRIPTION
Thequotacheck utility examines each file system, builds
a table of current disk usage, and compares this table against that recorded
in the disk quota file for the file system. 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 file system is
checked). By default both user and group quotas are checked.
The following options are available:
-a- If supplied in place of any file system names,
quotacheckwill check all the file systems 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- Report 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 file systems required, using the pass numbers in
/etc/fstab in an identical fashion to
fsck(8).
Normally, quotacheck operates
silently.
The quotacheck utility expects each file
system 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. These files
should be edited with the
edquota(8) utility.
The quotacheck utility 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.
The quotacheck utility accesses the raw
device in calculating the actual disk usage for each user. Thus, the file
systems checked should be quiescent while quotacheck
is running.
