16 quotaon
17 quotaon announces to the system that disk quotas should be enabled on
18 one or more filesystems. The filesystem quota files must be present in
19 the root directory of the specified filesystem and be named either
20 aquota.user (for version 2 user quota), quota.user (for version 1 user
21 quota), aquota.group (for version 2 group quota), or quota.group (for
22 version 1 group quota).
23 XFS filesystems are a special case - XFS considers quota information as
25 filesystem metadata and uses journaling to provide a higher level guar‐
26 antee of consistency. There are two components to the XFS disk quota
27 system: accounting and limit enforcement. XFS filesystems require that
28 quota accounting be turned on at mount time. It is possible to enable
29 and disable limit enforcement on an XFS filesystem after quota account‐
30 ing is already turned on. The default is to turn on both accounting
31 and enforcement.
32 The XFS quota implementation does not maintain quota information in
34 user-visible files, but rather stores this information internally.
35 quotaoff
37 quotaoff announces to the system that the specified filesystems should
38 have any disk quotas turned off.
39
41 quotaon
42 -F, --format=format-name
43 Report quota for specified format (ie. don't perform format
44 autodetection). Possible format names are: vfsold Original
45 quota format with 16-bit UIDs / GIDs, vfsv0 Quota format with
46 32-bit UIDs / GIDs, 64-bit space usage, 32-bit inode usage and
47 limits, vfsv1 Quota format with 64-bit quota limits and usage,
48 xfs (quota on XFS filesystem)
49 -a, --all
51 All automatically mounted (no noauto option) non-NFS filesystems
52 in /etc/fstab with quotas will have their quotas turned on.
53 This is normally used at boot time to enable quotas.
54 -v, --verbose
56 Display a message for each filesystem where quotas are turned
57 on.
58 -u, --user
60 Manipulate user quotas. This is the default.
61 -g, --group
63 Manipulate group quotas.
64 -P, --project
66 Manipulate project quotas.
67 -p, --print-state
69 Instead of turning quotas on just print state of quotas (ie.
70 whether. quota is on or off)
71 -x, --xfs-command enforce
73 Switch on limit enforcement for XFS filesystems. This is the
74 default action for any XFS filesystem. This option is only
75 applicable to XFS, and is silently ignored for other filesystem
76 types.
77 -f, --off
79 Make quotaon behave like being called as quotaoff.
80 quotaoff
82 -F, --format=format-name
83 Report quota for specified format (ie. don't perform format
84 autodetection). Possible format names are: vfsold (version 1
85 quota), vfsv0 (version 2 quota), xfs (quota on XFS filesystem)
86 -a, --all
88 Force all filesystems in /etc/fstab to have their quotas dis‐
89 abled.
90 -v, --verbose
92 Display a message for each filesystem affected.
93 -u, --user
95 Manipulate user quotas. This is the default.
96 -g, --group
98 Manipulate group quotas.
99 -P, --project
101 Manipulate project quotas.
102 -p, --print-state
104 Instead of turning quotas off just print state of quotas (ie.
105 whether. quota is on or off)
106 -x, --xfs-command delete
108 Free up the space used to hold quota information (maintained
109 internally) within XFS. This option is only applicable to XFS,
110 and is silently ignored for other filesystem types. It can only
111 be used on a filesystem with quota previously turned off.
112 -x, --xfs-command enforce
114 Switch off limit enforcement for XFS filesystems (perform quota
115 accounting only). This is the default action for any XFS
116 filesystem. This option is only applicable to XFS, and is
117 silently ignored for other filesystem types.
118 -x, --xfs-command account
120 This option can be used to disable quota accounting. It is not
121 possible to enable quota accounting by quota tools. Use mount(8)
122 for that. This option is only applicable to XFS filesystems, and
123 is silently ignored for other filesystem types.
124
126 To enable quotas on an XFS filesystem, use mount(8) or /etc/fstab quota
127 option to enable both accounting and limit enforcement. quotaon util‐
128 ity cannot be used for this purpose.
129 Turning on quotas on an XFS root filesystem requires the quota mount
131 options be passed into the kernel at boot time through the Linux root‐
132 flags boot option.
133 To turn off quota limit enforcement on any XFS filesystem, first make
135 sure that quota accounting and enforcement are both turned on using
136 repquota -v filesystem. Then, use quotaoff -v filesystem to disable
137 limit enforcement. This may be done while the filesystem is mounted.
138 Turning on quota limit enforcement on an XFS filesystem is achieved
140 using quotaon -v filesystem. This may be done while the filesystem is
141 mounted.

144 aquota.user or aquota.group
145 quota file at the filesystem root (version 2 quota,
146 non-XFS filesystems)

149 non-XFS filesystems)
