14 vgdisplay shows the attributes of VGs, and the associated PVs and LVs.
15 vgs(8) is a preferred alternative that shows the same information and
17 more, using a more compact and configurable output format.

65 -A|--activevolumegroups
66 Only select active VGs. The VG is considered active if at least
67 one of its LVs is active.
68 --aligned
70 Use with --separator to align the output columns
71 --binary
73 Use binary values "0" or "1" instead of descriptive literal val‐
74 ues for columns that have exactly two valid values to report
75 (not counting the "unknown" value which denotes that the value
76 could not be determined).
77 -c|--colon
79 Generate colon separated output for easier parsing in scripts or
80 programs. Also see vgs(8) which provides considerably more con‐
81 trol over the output.
82 -C|--columns
84 Display output in columns, the equivalent of vgs(8). Options
85 listed are the same as options given in vgs(8).
86 --commandprofile String
88 The command profile to use for command configuration. See
89 lvm.conf(5) for more information about profiles.
90 --config String
92 Config settings for the command. These override lvm.conf(5) set‐
93 tings. The String arg uses the same format as lvm.conf(5), or
94 may use section/field syntax. See lvm.conf(5) for more informa‐
95 tion about config.
96 --configreport log|vg|lv|pv|pvseg|seg
98 See lvmreport(7).
99 -d|--debug ...
101 Set debug level. Repeat from 1 to 6 times to increase the detail
102 of messages sent to the log file and/or syslog (if configured).
103 --devices PV
105 Restricts the devices that are visible and accessible to the
106 command. Devices not listed will appear to be missing. This op‐
107 tion can be repeated, or accepts a comma separated list of de‐
108 vices. This overrides the devices file.
109 --devicesfile String
111 A file listing devices that LVM should use. The file must exist
112 in /etc/lvm/devices/ and is managed with the lvmdevices(8) com‐
113 mand. This overrides the lvm.conf(5) devices/devicesfile and
114 devices/use_devicesfile settings.
115 --driverloaded y|n
117 If set to no, the command will not attempt to use device-mapper.
118 For testing and debugging.
119 --foreign
121 Report/display foreign VGs that would otherwise be skipped. See
122 lvmsystemid(7) for more information about foreign VGs.
123 -h|--help
125 Display help text.
126 --ignorelockingfailure
128 Allows a command to continue with read-only metadata operations
129 after locking failures.
130 --journal String
132 Record information in the systemd journal. This information is
133 in addition to information enabled by the lvm.conf log/journal
134 setting. command: record information about the command. out‐
135 put: record the default command output. debug: record full com‐
136 mand debugging.
137 --lockopt String
139 Used to pass options for special cases to lvmlockd. See lvm‐
140 lockd(8) for more information.
141 --logonly
143 Suppress command report and display only log report.
144 --longhelp
146 Display long help text.
147 --noheadings
149 Suppress the headings line that is normally the first line of
150 output. Useful if grepping the output.
151 --nohints
153 Do not use the hints file to locate devices for PVs. A command
154 may read more devices to find PVs when hints are not used. The
155 command will still perform standard hint file invalidation where
156 appropriate.
157 --nolocking
159 Disable locking. Use with caution, concurrent commands may pro‐
160 duce incorrect results.
161 --nosuffix
163 Suppress the suffix on output sizes. Use with --units (except h
164 and H) if processing the output.
165 -o|--options String
167 Comma-separated, ordered list of fields to display in columns.
168 String arg syntax is: [+|-|#]Field1[,Field2 ...] The prefix +
169 will append the specified fields to the default fields, - will
170 remove the specified fields from the default fields, and # will
171 compact specified fields (removing them when empty for all
172 rows.) Use -o help to view the list of all available fields.
173 Use separate lists of fields to add, remove or compact by re‐
174 peating the -o option: -o+field1,field2 -o-field3,field4
175 -o#field5. These lists are evaluated from left to right. Use
176 field name lv_all to view all LV fields, vg_all all VG fields,
177 pv_all all PV fields, pvseg_all all PV segment fields, seg_all
178 all LV segment fields, and pvseg_all all PV segment columns.
179 See the lvm.conf(5) report section for more config options. See
180 lvmreport(7) for more information about reporting.
181 --profile String
183 An alias for --commandprofile or --metadataprofile, depending on
184 the command.
185 -q|--quiet ...
187 Suppress output and log messages. Overrides --debug and --ver‐
188 bose. Repeat once to also suppress any prompts with answer
189 'no'.
190 --readonly
192 Run the command in a special read-only mode which will read on-
193 disk metadata without needing to take any locks. This can be
194 used to peek inside metadata used by a virtual machine image
195 while the virtual machine is running. No attempt will be made to
196 communicate with the device-mapper kernel driver, so this option
197 is unable to report whether or not LVs are actually in use.
198 -S|--select String
200 Select objects for processing and reporting based on specified
201 criteria. The criteria syntax is described by --select help and
202 lvmreport(7). For reporting commands, one row is displayed for
203 each object matching the criteria. See --options help for se‐
204 lectable object fields. Rows can be displayed with an addition‐
205 al "selected" field (-o selected) showing 1 if the row matches
206 the selection and 0 otherwise. For non-reporting commands which
207 process LVM entities, the selection is used to choose items to
208 process.
209 --separator String
211 String to use to separate each column. Useful if grepping the
212 output.
213 --shared
215 Report/display shared VGs that would otherwise be skipped when
216 lvmlockd is not being used on the host. See lvmlockd(8) for
217 more information about shared VGs.
218 -s|--short
220 Give a short listing showing the existence of VGs.
221 -O|--sort String
223 Comma-separated ordered list of columns to sort by. Replaces the
224 default selection. Precede any column with - for a reverse sort
225 on that column.
226 -t|--test
228 Run in test mode. Commands will not update metadata. This is
229 implemented by disabling all metadata writing but nevertheless
230 returning success to the calling function. This may lead to un‐
231 usual error messages in multi-stage operations if a tool relies
232 on reading back metadata it believes has changed but hasn't.
233 --unbuffered
235 Produce output immediately without sorting or aligning the col‐
236 umns properly.
237 --units [Number]r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E
239 All sizes are output in these units: human-(r)eadable with '<'
240 rounding indicator, (h)uman-readable, (b)ytes, (s)ectors,
241 (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes,
242 (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead
243 of 1024. Custom units can be specified, e.g. --units 3M.
244 -v|--verbose ...
246 Set verbose level. Repeat from 1 to 4 times to increase the de‐
247 tail of messages sent to stdout and stderr.
248 --version
250 Display version information.
251 -y|--yes
253 Do not prompt for confirmation interactively but always assume
254 the answer yes. Use with extreme caution. (For automatic no,
255 see -qq.)
256
258 VG Volume Group name. See lvm(8) for valid names.
259 Tag Tag name. See lvm(8) for information about tag names and using
261 tags in place of a VG, LV or PV.
262 String See the option description for information about the string con‐
264 tent.
265 Size[UNIT]
267 Size is an input number that accepts an optional unit. Input
268 units are always treated as base two values, regardless of capi‐
269 talization, e.g. 'k' and 'K' both refer to 1024. The default
270 input unit is specified by letter, followed by |UNIT. UNIT rep‐
271 resents other possible input units: b|B is bytes, s|S is sectors
272 of 512 bytes, k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB,
273 p|P is PiB, e|E is EiB. (This should not be confused with the
274 output control --units, where capital letters mean multiple of
275 1000.)
276
278 See lvm(8) for information about environment variables used by lvm.
279 For example, LVM_VG_NAME can generally be substituted for a required VG
280 parameter.
