46 announces to the system that disk quotas should be enabled on one or
47 more filesystems. The filesystem quota files must be present in the root
48 directory of the specified filesystem and be named either
50 (for version 2 user quota),
52 (for version 1 user quota),
54 (for version 2 group quota), or
56 (for version 1 group quota).
58 XFS filesystems are a special case - XFS considers quota
59 information as filesystem metadata and uses journaling to provide
60 a higher level guarantee of consistency.
61 There are two components to the XFS disk quota system:
62 accounting and limit enforcement.
63 XFS filesystems require that quota accounting be turned on at mount time.
64 It is possible to enable and disable limit enforcement on an XFS
65 filesystem after quota accounting is already turned on.
66 The default is to turn on both accounting and enforcement.
68 The XFS quota implementation does not maintain quota information in
69 user-visible files, but rather stores this information internally.

78 announces to the system that the specified filesystems should
79 have any disk quotas turned off.
84 All automatically mounted (no
86 option) non-NFS filesystems in
88 with quotas will have their quotas turned on.
89 This is normally used at boot time to enable quotas.
92 Display a message for each filesystem where quotas are turned on.
95 Manipulate user quotas. This is the default.
98 Manipulate group quotas.

111 Report quota for specified format (ie. don't perform format autodetection).
112 Possible format names are:
118 (quota on XFS filesystem)
121 Force all filesystems in
123 to have their quotas disabled.
126 Display a message for each filesystem affected.
129 Manipulate user quotas. This is the default.
132 Manipulate group quotas.
135 Instead of turning quotas off just print state of quotas (ie. whether. quota is on or off)
138 Free up the space used to hold quota information (maintained
139 internally) within XFS.
140 This option is only applicable to XFS, and is silently
141 ignored for other filesystem types.
142 It can only be used on a filesystem with quota previously turned off.
145 Switch off limit enforcement for XFS filesystems (perform
146 quota accounting only).

150 To enable quotas on an XFS filesystem, use
154 quota option to enable both accounting and limit enforcement.
156 utility cannot be used for this purpose.
158 Turning on quotas on an XFS root filesystem requires the quota mount
159 options be passed into the kernel at boot time through the Linux
163 To turn off quota limit enforcement on any XFS filesystem, first make
164 sure that quota accounting and enforcement are both turned on using
168 to disable limit enforcement.
169 This may be done while the filesystem is mounted.
