NAME
quotaon, quotaoff - turn filesystem quotas on and off
SYNOPSIS
- /usr/sbin/quotaon
- REDIRECT Template:arg/opt filesystem...
- /usr/sbin/quotaon
- REDIRECT Template:fmt/arg/opt
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. 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.
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. |
-f | Make quotaon behave like being called as quotaoff. |
quotaoff
-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. |
-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. |
XFS EXAMPLES
- 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:
- Turning off quota limit enforcement on any XFS filesystem:
- Turning on quota limit enforcement on any XFS filesystem:
FILES
- aquota.user or aquota.group
- quota file at the filesystem root (version 2 quota, non-XFS
- quota.user or quota.group
- quota file at the filesystem root (version 1 quota, non-XFS filesystems)
- /etc/fstab
- default filesystems
