DESCRIPTION

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
24       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
33       The  XFS  quota  implementation  does not maintain quota information in
34       user-visible files, but rather stores this information internally.
35
36   quotaoff
37       quotaoff announces to the system that the specified filesystems  should
38       have any disk quotas turned off.

OPTIONS

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
50       -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
55       -v, --verbose
56              Display a message for each filesystem where  quotas  are  turned
57              on.
58
59       -u, --user
60              Manipulate user quotas. This is the default.
61
62       -g, --group
63              Manipulate group quotas.
64
65       -p, --print-state
66              Instead  of  turning  quotas  on just print state of quotas (ie.
67              whether. quota is on or off)
68
69       -x, --xfs-command enforce
70              Switch on limit enforcement for XFS  filesystems.  This  is  the
71              default  action  for  any  XFS  filesystem.  This option is only
72              applicable to XFS, and is silently ignored for other  filesystem
73              types.
74
75       -f, --off
76              Make quotaon behave like being called as quotaoff.
77
78   quotaoff
79       -F, --format=format-name
80              Report  quota  for  specified  format  (ie. don't perform format
81              autodetection).  Possible format names are:  vfsold  (version  1
82              quota), vfsv0 (version 2 quota), xfs (quota on XFS filesystem)
83
84       -a, --all
85              Force  all  filesystems  in /etc/fstab to have their quotas dis‐
86              abled.
87
88       -v, --verbose
89              Display a message for each filesystem affected.
90
91       -u, --user
92              Manipulate user quotas. This is the default.
93
94       -g, --group
95              Manipulate group quotas.
96
97       -p, --print-state
98              Instead of turning quotas off just print state  of  quotas  (ie.
99              whether. quota is on or off)
100
101       -x, --xfs-command delete
102              Free  up  the  space  used to hold quota information (maintained
103              internally) within XFS.  This option is only applicable to  XFS,
104              and is silently ignored for other filesystem types.  It can only
105              be used on a filesystem with quota previously turned off.
106
107       -x, --xfs-command enforce
108              Switch off limit enforcement for XFS filesystems (perform  quota
109              accounting  only).  This  is  the  default  action  for  any XFS
110              filesystem.  This option is  only  applicable  to  XFS,  and  is
111              silently ignored for other filesystem types.
112
113       -x, --xfs-command account
114              This  option  can be used to disable quota accounting. It is not
115              possible to enable quota accounting by quota tools. Use mount(8)
116              for that. This option is only applicable to XFS filesystems, and
117              is silently ignored for other filesystem types.

NOTES ON XFS FILESYSTEMS

120       To enable quotas on an XFS filesystem, use mount(8) or /etc/fstab quota
121       option  to enable both accounting and limit enforcement.  quotaon util‐
122       ity cannot be used for this purpose.
123
124       Turning on quotas on an XFS root filesystem requires  the  quota  mount
125       options  be passed into the kernel at boot time through the Linux root‐
126       flags boot option.
127
128       To turn off quota limit enforcement on any XFS filesystem,  first  make
129       sure  that  quota  accounting  and enforcement are both turned on using
130       repquota -v filesystem.  Then, use quotaoff -v  filesystem  to  disable
131       limit enforcement.  This may be done while the filesystem is mounted.
132
133       Turning  on  quota  limit  enforcement on an XFS filesystem is achieved
134       using quotaon -v filesystem.  This may be done while the filesystem  is
135       mounted.
