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



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
