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

NAME
     quotacheck -- filesystem quota consistency checker

SYNOPSIS
     quotacheck [-g] [-u] [-v] filesystem ...
     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 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 read-write filesystems with an existing mount option file at its root.  The
	     mount option file specifies the types of quotas that are to be checked.

     -g      Only group quotas are checked. The mount option file, .quota.ops.group, must exist
	     at the root of the filesystem.

     -u      Only user quotas are checked.  The mount option file, .quota.ops.user, must exist at
	     the root of the filesystem.

     -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, in an identical fashion to fsck(8).

     Normally quotacheck operates silently.

     Quotacheck expects each filesystem being checked to have quota data files named .quota.user
     and/or .quota.group located at the filesystem root.  If a binary data file is not present,
     quotacheck will create it.  The default filename and root location cannot be overridden.

     Quotacheck is normally run at fsck time.

     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
     Each of the following quota files is located at the root of the mounted filesystem.  The
     mount option files are empty files whose existence indicates that quotas are to be enabled
     for that filesystem. The binary data files will be created by quotacheck, if they don't
     already exist.

     .quota.user       data file containing user quotas
     .quota.group      data file containing group quotas
     .quota.ops.user   mount option file used to enable user quotas
     .quota.ops.group  mount option file used to enable group quotas
