QUOTAON(8)							    QUOTAON(8)

NAME
       quotaon, quotaoff - turn filesystem quotas on and off

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

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

DESCRIPTION
   quotaon
       quotaon	announces  to the system that disk quotas should be enabled on
       one or more filesystems. 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
       version 1 group quota).

       XFS filesystems are a special case - XFS considers quota information as
       filesystem metadata and uses journaling to provide a higher level guar‐
       antee of consistency.  There are two components to the XFS  disk	 quota
       system: accounting and limit enforcement.  XFS filesystems require that
       quota accounting be turned on at mount time.  It is possible to	enable
       and disable limit enforcement on an XFS filesystem after quota account‐
       ing 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 quotas turned off.

OPTIONS
   quotaon
       -F, --format=format-name
	      Report  quota  for  specified  format  (ie. don't perform format
	      autodetection).  Possible	 format	 names	are:  vfsold  Original
	      quota  format  with  16-bit UIDs / GIDs, vfsv0 Quota format with
	      32-bit UIDs / GIDs, 64-bit space usage, 32-bit inode  usage  and
	      limits,  vfsv1  Quota format with 64-bit quota limits and usage,
	      xfs (quota on XFS filesystem)

       -a, --all
	      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, --verbose
	      Display a message for each filesystem where  quotas  are	turned
	      on.

       -u, --user
	      Manipulate user quotas. This is the default.

       -g, --group
	      Manipulate group quotas.

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

       -x, --xfs-command enforce
	      Switch on limit enforcement for XFS  filesystems.	 This  is  the
	      default  action  for  any	 XFS  filesystem.  This option is only
	      applicable to XFS, and is silently ignored for other  filesystem
	      types.

       -f, --off
	      Make quotaon behave like being called as quotaoff.

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

       -a, --all
	      Force  all  filesystems  in /etc/fstab to have their quotas dis‐
	      abled.

       -v, --verbose
	      Display a message for each filesystem affected.

       -u, --user
	      Manipulate user quotas. This is the default.

       -g, --group
	      Manipulate group quotas.

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

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

       -x, --xfs-command account
	      This  option  can be used to disable quota accounting. It is not
	      possible to enable quota accounting by quota tools. Use mount(8)
	      for that. This option is only applicable to XFS filesystems, and
	      is silently ignored for other filesystem types.

NOTES ON XFS FILESYSTEMS
       To enable quotas on an XFS filesystem, use mount(8) or /etc/fstab quota
       option  to enable both accounting and limit enforcement.	 quotaon util‐
       ity cannot be used for this purpose.

       Turning on quotas on an XFS root filesystem requires  the  quota	 mount
       options	be passed into the kernel at boot time through the Linux root‐
       flags boot option.

       To turn off quota limit enforcement on any XFS filesystem,  first  make
       sure  that  quota  accounting  and enforcement are both turned on using
       repquota -v filesystem.	Then, use quotaoff -v  filesystem  to  disable
       limit enforcement.  This may be done while the filesystem is mounted.

       Turning	on  quota  limit  enforcement on an XFS filesystem is achieved
       using quotaon -v filesystem.  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 filesystems)
       quota.user or quota.group
			   quota file at the filesystem root (version 1 quota,
			   non-XFS filesystems)
       /etc/fstab	   default filesystems
