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
       guarantee 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 disabled.

       -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
