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  pro-
       vide  a  higher  level  guarantee  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 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  informa-
       tion 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
              (version 1 quota), vfsv0 (version 2 quota), 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)

       -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 disabled.

       -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 applica-
              ble  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 on/off limit enforcement for XFS filesystems (perform quota accounting only).  This option is only applica-
              ble 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 utility 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 rootflags 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
