Описание (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.
Параметры (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, --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.
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.
Файлы (Files)
