    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

    -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.
     

    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 -s. Then, use quotaoff -vo 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. 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
     

    SEE ALSO

    quotactl(2), fstab(5), repquota(8).
