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.

62 -A|--activevolumegroups
63 Only select active VGs. The VG is considered active if at least
64 one of its LVs is active.
65 --aligned
67 Use with --separator to align the output columns
68 --binary
70 Use binary values "0" or "1" instead of descriptive literal val‐
71 ues for columns that have exactly two valid values to report
72 (not counting the "unknown" value which denotes that the value
73 could not be determined).
74 -c|--colon
76 Generate colon separated output for easier parsing in scripts or
77 programs. Also see vgs(8) which provides considerably more con‐
78 trol over the output.
79 -C|--columns
81 Display output in columns, the equivalent of vgs(8). Options
82 listed are the same as options given in vgs(8).
83 --commandprofile String
85 The command profile to use for command configuration. See
86 lvm.conf(5) for more information about profiles.
87 --config String
89 Config settings for the command. These override lvm.conf set‐
90 tings. The String arg uses the same format as lvm.conf, or may
91 use section/field syntax. See lvm.conf(5) for more information
92 about config.
93 --configreport log|vg|lv|pv|pvseg|seg
95 See lvmreport(7).
96 -d|--debug ...
98 Set debug level. Repeat from 1 to 6 times to increase the detail
99 of messages sent to the log file and/or syslog (if configured).
100 --driverloaded y|n
102 If set to no, the command will not attempt to use device-mapper.
103 For testing and debugging.
104 --foreign
106 Report/display foreign VGs that would otherwise be skipped. See
107 lvmsystemid(7) for more information about foreign VGs.
108 -h|--help
110 Display help text.
111 --ignorelockingfailure
113 Allows a command to continue with read-only metadata operations
114 after locking failures.
115 --lockopt String
117 Used to pass options for special cases to lvmlockd. See lvm‐
118 lockd(8) for more information.
119 --logonly
121 Suppress command report and display only log report.
122 --longhelp
124 Display long help text.
125 --noheadings
127 Suppress the headings line that is normally the first line of
128 output. Useful if grepping the output.
129 --nolocking
131 Disable locking.
132 --nosuffix
134 Suppress the suffix on output sizes. Use with --units (except h
135 and H) if processing the output.
136 -o|--options String
138 Comma-separated, ordered list of fields to display in columns.
139 String arg syntax is: [+|-|#]Field1[,Field2 ...] The prefix +
140 will append the specified fields to the default fields, - will
141 remove the specified fields from the default fields, and # will
142 compact specified fields (removing them when empty for all
143 rows.) Use -o help to view the list of all available fields.
144 Use separate lists of fields to add, remove or compact by re‐
145 peating the -o option: -o+field1,field2 -o-field3,field4
146 -o#field5. These lists are evaluated from left to right. Use
147 field name lv_all to view all LV fields, vg_all all VG fields,
148 pv_all all PV fields, pvseg_all all PV segment fields, seg_all
149 all LV segment fields, and pvseg_all all PV segment columns.
150 See the lvm.conf report section for more config options. See
151 lvmreport(7) for more information about reporting.
152 --profile String
154 An alias for --commandprofile or --metadataprofile, depending on
155 the command.
156 -q|--quiet ...
158 Suppress output and log messages. Overrides --debug and --ver‐
159 bose. Repeat once to also suppress any prompts with answer
160 'no'.
161 --readonly
163 Run the command in a special read-only mode which will read on-
164 disk metadata without needing to take any locks. This can be
165 used to peek inside metadata used by a virtual machine image
166 while the virtual machine is running. No attempt will be made to
167 communicate with the device-mapper kernel driver, so this option
168 is unable to report whether or not LVs are actually in use.
169 --reportformat basic|json
171 Overrides current output format for reports which is defined
172 globally by the report/output_format setting in lvm.conf. basic
173 is the original format with columns and rows. If there is more
174 than one report per command, each report is prefixed with the
175 report name for identification. json produces report output in
176 JSON format. See lvmreport(7) for more information.
177 -S|--select String
179 Select objects for processing and reporting based on specified
180 criteria. The criteria syntax is described by --select help and
181 lvmreport(7). For reporting commands, one row is displayed for
182 each object matching the criteria. See --options help for se‐
183 lectable object fields. Rows can be displayed with an addi‐
184 tional "selected" field (-o selected) showing 1 if the row
185 matches the selection and 0 otherwise. For non-reporting com‐
186 mands which process LVM entities, the selection is used to
187 choose items to process.
188 --separator String
190 String to use to separate each column. Useful if grepping the
191 output.
192 --shared
194 Report/display shared VGs that would otherwise be skipped when
195 lvmlockd is not being used on the host. See lvmlockd(8) for
196 more information about shared VGs.
197 -s|--short
199 Give a short listing showing the existence of VGs.
200 -O|--sort String
202 Comma-separated ordered list of columns to sort by. Replaces the
203 default selection. Precede any column with - for a reverse sort
204 on that column.
205 -t|--test
207 Run in test mode. Commands will not update metadata. This is
208 implemented by disabling all metadata writing but nevertheless
209 returning success to the calling function. This may lead to un‐
210 usual error messages in multi-stage operations if a tool relies
211 on reading back metadata it believes has changed but hasn't.
212 --unbuffered
214 Produce output immediately without sorting or aligning the col‐
215 umns properly.
216 --units r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E
218 All sizes are output in these units: human-(r)eadable with '<'
219 rounding indicator, (h)uman-readable, (b)ytes, (s)ectors,
220 (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes,
221 (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead
222 of 1024. Custom units can be specified, e.g. --units 3M.
223 -v|--verbose ...
225 Set verbose level. Repeat from 1 to 4 times to increase the de‐
226 tail of messages sent to stdout and stderr.
227 --version
229 Display version information.
230 -y|--yes
232 Do not prompt for confirmation interactively but always assume
233 the answer yes. Use with extreme caution. (For automatic no,
234 see -qq.)
235
237 VG
238 Volume Group name. See lvm(8) for valid names.
239 Tag
241 Tag name. See lvm(8) for information about tag names and using
242 tags in place of a VG, LV or PV.
243 String
245 See the option description for information about the string con‐
246 tent.
247 Size[UNIT]
249 Size is an input number that accepts an optional unit. Input
250 units are always treated as base two values, regardless of capi‐
251 talization, e.g. 'k' and 'K' both refer to 1024. The default
252 input unit is specified by letter, followed by |UNIT. UNIT rep‐
253 resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
254 bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M is MiB, g|G
255 is GiB, t|T is TiB, p|P is PiB, e|E is EiB. (This should not be
256 confused with the output control --units, where capital letters
257 mean multiple of 1000.)
258
260 See lvm(8) for information about environment variables used by lvm.
261 For example, LVM_VG_NAME can generally be substituted for a required VG
262 parameter.
