QUOTAON(8)                                                         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 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
       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  pos-
       sible  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 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 filesys-
              tems 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
       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 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
