SYNOPSIS

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

/usr/sbin/quotaoff [ -avugp ]

DESCRIPTION

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, --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, --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
