NAME

       quotaon, quotaoff - turn filesystem quotas on and off

SYNOPSIS

       quotaon [ -vugfp ] [ -F format-name ] filesystem...
       quotaon [ -avugPfp ] [ -F format-name ]

       quotaoff [ -vugPp ] [ -x state ] filesystem...
       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  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 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, --project
              Manipulate project 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 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, --project
              Manipulate project 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 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
