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 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 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

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

NAME

     quotaon, quotaoff -- turn filesystem quotas on and off

SYNOPSIS

     quotaon [-g] [-u] [-v] filesystem ...
     quotaon [-g] [-u] [-v] -a
     quotaoff [-g] [-u] [-v] filesystem ...
     quotaoff [-g] [-u] [-v] -a

DESCRIPTION

     Quotaon announces to the system that disk quotas should be enabled on one or more filesystems.  Quotaoff announces to the system that the
     specified filesystems should have disk quotas turned off.	The filesystem must be mounted and it must have the appropriate mount option file
     located at its root, the .quota.ops.user file for user quota configuration, and the .quota.ops.group file for group quota configuration.
     Quotaon also expects each filesystem to have the appropriate quota data files located at its root, the .quota.user file for user data, and
     the .quota.group file for group data.  These filenames and their root location cannot be overridden.  By default, quotaon will attempt to
     enable both user and group quotas.  By default, quotaoff will disable both user and group quotas.

     Available options:

     -a      If the -a flag is supplied in place of any filesystem names, quotaon/quotaoff will enable/disable any filesystems with an existing
	     mount option file at its root.  The mount option file specifies the types of quotas that are to be configured.

     -g      Only group quotas will be enabled/disabled.  The mount option file, .quota.ops.group, must exist at the root of the filesystem.

     -u      Only user quotas will be enabled/disabled.  The mount option file, .quota.ops.user, must exist at the root of the filesystem.

     -v      Causes quotaon and quotaoff to print a message for each filesystem where quotas are turned on or off.

     Specifying both -g and -u is equivalent to the default.

     Quotas for both users and groups will automatically be turned on at filesystem mount if the appropriate mount option file and binary data
     file is in place at its root.

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.

     .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
