QUOTACHECK(8)               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 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      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 argument.  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 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
     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
