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.
