QUOTAON(8)                                                          QUOTAON(8)



NAME
       quotaon, quotaoff - turn filesystem quotas on and off

SYNOPSIS
       /sbin/quotaon [ -vugfp ] [ -F format-name ] filesystem...
       /sbin/quotaon [ -avugfp ] [ -F format-name ]

       /sbin/quotaoff [ -vugp ] [ -x state ] filesystem...
       /sbin/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 guar-
       antee of consistency.  There are two components to the XFS  disk  quota
       system:  accounting  and  limit enforcement.  Except in the case of the
       root filesystem, XFS  filesystems  require  that  quota  accounting  be
       turned  on  at  mount time.  It is possible to enable and disable limit
       enforcement on any 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
       -a     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     Display a message for each filesystem where  quotas  are  turned
              on.

       -u     Manipulate user quotas. This is the default.

       -g     Manipulate group quotas.

       -p     Instead  of  turning  quotas  on just print state of quotas (ie.
              whether. quota is on or off)

       -f     Make quotaon behave like being called as quotaoff.

   quotaoff
       -F 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     Force all filesystems in /etc/fstab to have  their  quotas  dis-
              abled.

       -v     Display a message for each filesystem affected.

       -u     Manipulate user quotas. This is the default.

       -g     Manipulate group quotas.

       -p     Instead  of  turning  quotas off just print state of quotas (ie.
              whether. quota is on or off)

       -x 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 enforce
              Switch  off limit enforcement for XFS filesystems (perform quota
              accounting only).  This option is only applicable to XFS, and is
              silently ignored for other filesystem types.


XFS EXAMPLES
       Turning on quotas on a non-root XFS filesystem
       Use  mount(8)  or /etc/fstab option quota to enable both accounting and
       limit enforcement.  quotaon utility cannot be used for this purpose.

       Turning on quotas on an XFS root filesystem
       Use quotaon -v /, and  reboot(8).   This  procedure  will  enable  both
       accounting and limit enforcement.

       Turning off quota limit enforcement on any XFS filesystem
       Make  sure  that  quota  accounting  and enforcement are both turned on
       using repquota -s.  Use quotaoff  -vo  to  disable  limit  enforcement.
       This may be done while the filesystem is mounted.

       Turning on quota limit enforcement on any XFS filesystem
       Make  sure  that  quota accounting is turned on using repquota -s.  Use
       quotaon -v.  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
