QUOTACHECK(8) OpenBSD System Manager's Manual QUOTACHECK(8)
quotacheck - filesystem quota consistency checker
quotacheck [-d] [-g] [-u] [-v] filesystem ...
quotacheck [-d] [-g] [-l maxparallel] [-u] [-v] -a
Quotacheck examines each filesystem, builds a table of current disk us-
age, 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.
-a 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.
-d Enable debugging mode, no actual data will be written on disk(s).
-g Only group quotas listed in /etc/fstab are to be checked.
Limit the number of parallel checks to the number maxparallel
specified in the argument (see fsck(8)).
-u Only user quotas listed in /etc/fstab are to be checked.
-v quotacheck 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, 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 as-
sociated 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.
