QUOTAON(8)               System Manager's Manual              QUOTAON(8)

NAME         top

       quotaon, quotaoff - turn filesystem quotas on and off

SYNOPSIS         top

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

       quotaoff [ -vugPp ] [ -x state ] filesystem...
       quotaoff [ -avugp ]

DESCRIPTION         top

   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         top

   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         top

       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.
