quotaon


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

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