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

NAME
       quotaon, quotaoff - turn filesystem quotas on and off

SYNOPSIS
       /sbin/quotaon [ -vugfp ] [ -F format-name ] filesystem...
       /sbin/quotaon [ -avugfp ] [ -F format-name ]

       /sbin/quotaoff [ -vugp ] [ -x state ] filesystem...
       /sbin/quotaoff [ -avugp ]

DESCRIPTION
   quotaon
       quotaon announces to the system that disk quotas should be enabled on one or more filesys-
       tems. The filesystem quota files must be present in the root directory  of  the	specified
       filesystem  and	be  named  either aquota.user (for version 2 user quota), quota.user (for
       version 1 user quota), aquota.group (for version 2 group quota), or quota.group (for  ver-
       sion 1 group quota).

       XFS  filesystems  are a special case - XFS considers quota information as filesystem meta-
       data and uses journaling to provide a higher level guarantee of	consistency.   There  are
       two  components to the XFS disk quota system: accounting and limit enforcement.	Except in
       the case of the root filesystem, XFS filesystems require that quota accounting  be  turned
       on  at  mount  time.   It  is  possible to enable and disable limit enforcement on any XFS
       filesystem after quota accounting is already turned on.	The default is to  turn  on  both
       accounting and enforcement.

       The  XFS  quota	implementation does not maintain quota information in user-visible files,
       but rather stores this information internally.

   quotaoff
       quotaoff announces to the system that the specified filesystems should have any disk  quo-
       tas turned off.

OPTIONS
   quotaon
       -a     All automatically mounted (no noauto option) non-NFS filesystems in /etc/fstab with
	      quotas will have their quotas turned on.	This is normally used  at  boot  time  to
	      enable quotas.

       -v     Display a message for each filesystem where quotas are turned on.

       -u     Manipulate user quotas. This is the default.

       -g     Manipulate group quotas.

       -p     Instead  of  turning quotas on just print state of quotas (ie. whether. quota is on
	      or off)

       -f     Make quotaon behave like being called as quotaoff.

   quotaoff
       -F format-name
	      Report quota for specified format (ie. don't perform format autodetection).  Possi-
	      ble format names are: vfsold (version 1 quota), vfsv0 (version 2 quota), xfs (quota
	      on XFS filesystem)

       -a     Force all filesystems in /etc/fstab to have their quotas disabled.

       -v     Display a message for each filesystem affected.

       -u     Manipulate user quotas. This is the default.

       -g     Manipulate group quotas.

       -p     Instead of turning quotas off just print state of quotas (ie. whether. quota is  on
	      or off)

       -x delete
	      Free  up	the  space  used to hold quota information (maintained internally) within
	      XFS.  This option is only applicable to XFS, and	is  silently  ignored  for  other
	      filesystem types.  It can only be used on a filesystem with quota previously turned
	      off.

       -x enforce
	      Switch off limit enforcement for XFS filesystems (perform quota  accounting  only).
	      This option is only applicable to XFS, and is silently ignored for other filesystem
	      types.

XFS EXAMPLES
       Turning on quotas on a non-root XFS filesystem
       Use mount(8) or /etc/fstab option quota to enable both accounting and  limit  enforcement.
       quotaon utility cannot be used for this purpose.

       Turning on quotas on an XFS root filesystem
       Use  quotaon  -v  /,  and reboot(8).  This procedure will enable both accounting and limit
       enforcement.

       Turning off quota limit enforcement on any XFS filesystem
       Make sure that quota accounting and enforcement are both turned on using repquota -s.  Use
       quotaoff  -vo  to  disable  limit  enforcement.	 This may be done while the filesystem is
       mounted.

       Turning on quota limit enforcement on any XFS filesystem
       Make sure that quota accounting is turned on using repquota -s.	Use quotaon -v.  This may
       be done while the filesystem is mounted.

FILES
       aquota.user or aquota.group
			   quota  file	at the filesystem root (version 2 quota, non-XFS filesys-
			   tems)
       quota.user or quota.group
			   quota file at the filesystem root (version 1 quota,	non-XFS  filesys-
			   tems)
       /etc/fstab	   default filesystems
