61 --aligned
62 Use with --separator to align the output columns
63 -a|--all
65 List all VGs. Equivalent to not specifying any VGs.
66 --binary
68 Use binary values "0" or "1" instead of descriptive literal val‐
69 ues for columns that have exactly two valid values to report
70 (not counting the "unknown" value which denotes that the value
71 could not be determined).
72 --commandprofile String
74 The command profile to use for command configuration. See
75 lvm.conf(5) for more information about profiles.
76 --config String
78 Config settings for the command. These override lvm.conf set‐
79 tings. The String arg uses the same format as lvm.conf, or may
80 use section/field syntax. See lvm.conf(5) for more information
81 about config.
82 --configreport log|vg|lv|pv|pvseg|seg
84 See lvmreport(7).
85 -d|--debug ...
87 Set debug level. Repeat from 1 to 6 times to increase the detail
88 of messages sent to the log file and/or syslog (if configured).
89 --driverloaded y|n
91 If set to no, the command will not attempt to use device-mapper.
92 For testing and debugging.
93 --foreign
95 Report/display foreign VGs that would otherwise be skipped. See
96 lvmsystemid(7) for more information about foreign VGs.
97 -h|--help
99 Display help text.
100 --ignorelockingfailure
102 Allows a command to continue with read-only metadata operations
103 after locking failures.
104 --ignoreskippedcluster
106 Use to avoid exiting with an non-zero status code if the command
107 is run without clustered locking and clustered VGs are skipped.
108 --lockopt String
110 Used to pass options for special cases to lvmlockd. See lvm‐
111 lockd(8) for more information.
112 --logonly
114 Suppress command report and display only log report.
115 --longhelp
117 Display long help text.
118 --nameprefixes
120 Add an "LVM2_" prefix plus the field name to the output. Useful
121 with --noheadings to produce a list of field=value pairs that
122 can be used to set environment variables (for example, in udev
123 rules).
124 --noheadings
126 Suppress the headings line that is normally the first line of
127 output. Useful if grepping the output.
128 --nolocking
130 Disable locking.
131 --nosuffix
133 Suppress the suffix on output sizes. Use with --units (except h
134 and H) if processing the output.
135 -o|--options String
137 Comma-separated, ordered list of fields to display in columns.
138 String arg syntax is: [+|-|#]Field1[,Field2 ...] The prefix +
139 will append the specified fields to the default fields, - will
140 remove the specified fields from the default fields, and # will
141 compact specified fields (removing them when empty for all
142 rows.) Use -o help to view the list of all available fields.
143 Use separate lists of fields to add, remove or compact by
144 repeating the -o option: -o+field1,field2 -o-field3,field4
145 -o#field5. These lists are evaluated from left to right. Use
146 field name lv_all to view all LV fields, vg_all all VG fields,
147 pv_all all PV fields, pvseg_all all PV segment fields, seg_all
148 all LV segment fields, and pvseg_all all PV segment columns.
149 See the lvm.conf report section for more config options. See
150 lvmreport(7) for more information about reporting.
151 --profile String
153 An alias for --commandprofile or --metadataprofile, depending on
154 the command.
155 -q|--quiet ...
157 Suppress output and log messages. Overrides --debug and --ver‐
158 bose. Repeat once to also suppress any prompts with answer
159 'no'.
160 --readonly
162 Run the command in a special read-only mode which will read on-
163 disk metadata without needing to take any locks. This can be
164 used to peek inside metadata used by a virtual machine image
165 while the virtual machine is running. It can also be used to
166 peek inside the metadata of clustered VGs when clustered locking
167 is not configured or running. No attempt will be made to commu‐
168 nicate with the device-mapper kernel driver, so this option is
169 unable to report whether or not LVs are actually in use.
170 --reportformat basic|json
172 Overrides current output format for reports which is defined
173 globally by the report/output_format setting in lvm.conf. basic
174 is the original format with columns and rows. If there is more
175 than one report per command, each report is prefixed with the
176 report name for identification. json produces report output in
177 JSON format. See lvmreport(7) for more information.
178 --rows
180 Output columns as rows.
181 -S|--select String
183 Select objects for processing and reporting based on specified
184 criteria. The criteria syntax is described by --select help and
185 lvmreport(7). For reporting commands, one row is displayed for
186 each object matching the criteria. See --options help for
187 selectable object fields. Rows can be displayed with an addi‐
188 tional "selected" field (-o selected) showing 1 if the row
189 matches the selection and 0 otherwise. For non-reporting com‐
190 mands which process LVM entities, the selection is used to
191 choose items to process.
192 --separator String
194 String to use to separate each column. Useful if grepping the
195 output.
196 --shared
198 Report/display shared VGs that would otherwise be skipped when
199 lvmlockd is not being used on the host. See lvmlockd(8) for
200 more information about shared VGs.
201 -O|--sort String
203 Comma-separated ordered list of columns to sort by. Replaces the
204 default selection. Precede any column with - for a reverse sort
205 on that column.
206 -t|--test
208 Run in test mode. Commands will not update metadata. This is
209 implemented by disabling all metadata writing but nevertheless
210 returning success to the calling function. This may lead to
211 unusual error messages in multi-stage operations if a tool
212 relies on reading back metadata it believes has changed but
213 hasn't.
214 --trustcache
216 Avoids certain device scanning during command processing. Do not
217 use.
218 --unbuffered
220 Produce output immediately without sorting or aligning the col‐
221 umns properly.
222 --units r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E
224 All sizes are output in these units: human-(r)eadable with '<'
225 rounding indicator, (h)uman-readable, (b)ytes, (s)ectors,
226 (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes,
227 (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead
228 of 1024. Custom units can be specified, e.g. --units 3M.
229 --unquoted
231 When used with --nameprefixes, output values in the field=value
232 pairs are not quoted.
233 -v|--verbose ...
235 Set verbose level. Repeat from 1 to 4 times to increase the
236 detail of messages sent to stdout and stderr.
237 --version
239 Display version information.
240 -y|--yes
242 Do not prompt for confirmation interactively but always assume
243 the answer yes. Use with extreme caution. (For automatic no,
244 see -qq.)
245
247 VG
248 Volume Group name. See lvm(8) for valid names.
249 Tag
251 Tag name. See lvm(8) for information about tag names and using
252 tags in place of a VG, LV or PV.
253 String
255 See the option description for information about the string con‐
256 tent.
257 Size[UNIT]
259 Size is an input number that accepts an optional unit. Input
260 units are always treated as base two values, regardless of capi‐
261 talization, e.g. 'k' and 'K' both refer to 1024. The default
262 input unit is specified by letter, followed by |UNIT. UNIT rep‐
263 resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
264 bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is
265 megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
266 e|E is exabytes. (This should not be confused with the output
267 control --units, where capital letters mean multiple of 1000.)
268
270 See lvm(8) for information about environment variables used by lvm.
271 For example, LVM_VG_NAME can generally be substituted for a required VG
272 parameter.
273
275 The vg_attr bits are:
276 1 Permissions: (w)riteable, (r)ead-only
278 2 Resi(z)eable
280 3 E(x)ported
282 4 (p)artial: one or more physical volumes belonging to the volume
284 group are missing from the system
285 5 Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere
287 6 (c)lustered, (s)hared
