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 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
       -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).  Possible 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 dis-
              abled.

       -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.


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 -s.  Then, use quotaoff  -vo  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.  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
