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.
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, --project
Manipulate project 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, --project
Manipulate project 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.
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.
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
quotactl(2), fstab(5), quota_nld(8), repquota(8), warnquota(8)
