quotaon

QUOTAON(8)						      System Manager's Manual							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
       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  (version	1  quota),
	      vfsv0 (version 2 quota), 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, --print-state
	      Instead of turning quotas on just print state of quotas (ie. whether. quota is on or off)

       -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, --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 on/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.

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 root-
       flags 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
