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.
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.
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.
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), repquota(8).
