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
