QUOTACHECK(8)			   BSD System Manager's Manual			    QUOTACHECK(8)

NAME
     quotacheck -- filesystem quota consistency checker

SYNOPSIS
     quotacheck [-gquv] filesystem ...
     quotacheck [-gquv] [-l maxparallel] -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 inconsisten-
     cies 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      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.  See also -l.

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

     -l maxparallel
	     Limit the number of parallel checks to the number specified in the following argu-
	     ment.  By default, the limit is the number of disks, running one process per disk.
	     If a smaller limit is given, the disks are checked round-robin, one file system at a
	     time.  This option is only valid with -a.

     -q      quotacheck runs more quickly, particularly on systems with sparse user id usage, but
	     fails to correct quotas for users [groups] not in the system user [group] database,
	     and owning no files on the filesystem, if the quota file incorrectly believes that
	     they do.

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

     -v      quotacheck is more verbose, and reports corrected discrepancies between the calcu-
	     lated 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 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, 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.

     If quotacheck receives a SIGINFO signal (see the status argument for stty(1)), a line will
     be written to the standard error output indicating the name of the device currently being
     checked and progress information.

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

HISTORY
     The quotacheck command appeared in 4.2BSD.
