62 --aligned
63 Use with --separator to align the output columns
64 -a|--all
66 Show information about devices that have not been initialized by
67 LVM, i.e. they are not PVs.
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 --commandprofile String
76 The command profile to use for command configuration. See
77 lvm.conf(5) for more information about profiles.
78 --config String
80 Config settings for the command. These override lvm.conf set‐
81 tings. The String arg uses the same format as lvm.conf, or may
82 use section/field syntax. See lvm.conf(5) for more information
83 about config.
84 --configreport log|vg|lv|pv|pvseg|seg
86 See lvmreport(7).
87 -d|--debug ...
89 Set debug level. Repeat from 1 to 6 times to increase the detail
90 of messages sent to the log file and/or syslog (if configured).
91 --driverloaded y|n
93 If set to no, the command will not attempt to use device-mapper.
94 For testing and debugging.
95 --foreign
97 Report/display foreign VGs that would otherwise be skipped. See
98 lvmsystemid(7) for more information about foreign VGs.
99 -h|--help
101 Display help text.
102 --ignorelockingfailure
104 Allows a command to continue with read-only metadata operations
105 after locking failures.
106 --ignoreskippedcluster
108 Use to avoid exiting with an non-zero status code if the command
109 is run without clustered locking and clustered VGs are skipped.
110 --lockopt String
112 Used to pass options for special cases to lvmlockd. See lvm‐
113 lockd(8) for more information.
114 --logonly
116 Suppress command report and display only log report.
117 --longhelp
119 Display long help text.
120 --nameprefixes
122 Add an "LVM2_" prefix plus the field name to the output. Useful
123 with --noheadings to produce a list of field=value pairs that
124 can be used to set environment variables (for example, in udev
125 rules).
126 --noheadings
128 Suppress the headings line that is normally the first line of
129 output. Useful if grepping the output.
130 --nolocking
132 Disable locking.
133 --nosuffix
135 Suppress the suffix on output sizes. Use with --units (except h
136 and H) if processing the output.
137 -o|--options String
139 Comma-separated, ordered list of fields to display in columns.
140 String arg syntax is: [+|-|#]Field1[,Field2 ...] The prefix +
141 will append the specified fields to the default fields, - will
142 remove the specified fields from the default fields, and # will
143 compact specified fields (removing them when empty for all
144 rows.) Use -o help to view the list of all available fields.
145 Use separate lists of fields to add, remove or compact by
146 repeating the -o option: -o+field1,field2 -o-field3,field4
147 -o#field5. These lists are evaluated from left to right. Use
148 field name lv_all to view all LV fields, vg_all all VG fields,
149 pv_all all PV fields, pvseg_all all PV segment fields, seg_all
150 all LV segment fields, and pvseg_all all PV segment columns.
151 See the lvm.conf report section for more config options. See
152 lvmreport(7) for more information about reporting.
153 --profile String
155 An alias for --commandprofile or --metadataprofile, depending on
156 the command.
157 -q|--quiet ...
159 Suppress output and log messages. Overrides --debug and --ver‐
160 bose. Repeat once to also suppress any prompts with answer
161 'no'.
162 --readonly
164 Run the command in a special read-only mode which will read on-
165 disk metadata without needing to take any locks. This can be
166 used to peek inside metadata used by a virtual machine image
167 while the virtual machine is running. It can also be used to
168 peek inside the metadata of clustered VGs when clustered locking
169 is not configured or running. No attempt will be made to commu‐
170 nicate with the device-mapper kernel driver, so this option is
171 unable to report whether or not LVs are actually in use.
172 --reportformat basic|json
174 Overrides current output format for reports which is defined
175 globally by the report/output_format setting in lvm.conf. basic
176 is the original format with columns and rows. If there is more
177 than one report per command, each report is prefixed with the
178 report name for identification. json produces report output in
179 JSON format. See lvmreport(7) for more information.
180 --rows
182 Output columns as rows.
183 --segments
185 Produces one line of output for each contiguous allocation of
186 space on each PV, showing the start (pvseg_start) and length
187 (pvseg_size) in units of physical extents.
188 -S|--select String
190 Select objects for processing and reporting based on specified
191 criteria. The criteria syntax is described by --select help and
192 lvmreport(7). For reporting commands, one row is displayed for
193 each object matching the criteria. See --options help for
194 selectable object fields. Rows can be displayed with an addi‐
195 tional "selected" field (-o selected) showing 1 if the row
196 matches the selection and 0 otherwise. For non-reporting com‐
197 mands which process LVM entities, the selection is used to
198 choose items to process.
199 --separator String
201 String to use to separate each column. Useful if grepping the
202 output.
203 --shared
205 Report/display shared VGs that would otherwise be skipped when
206 lvmlockd is not being used on the host. See lvmlockd(8) for
207 more information about shared VGs.
208 -O|--sort String
210 Comma-separated ordered list of columns to sort by. Replaces the
211 default selection. Precede any column with - for a reverse sort
212 on that column.
213 -t|--test
215 Run in test mode. Commands will not update metadata. This is
216 implemented by disabling all metadata writing but nevertheless
217 returning success to the calling function. This may lead to
218 unusual error messages in multi-stage operations if a tool
219 relies on reading back metadata it believes has changed but
220 hasn't.
221 --trustcache
223 Avoids certain device scanning during command processing. Do not
224 use.
225 --unbuffered
227 Produce output immediately without sorting or aligning the col‐
228 umns properly.
229 --units r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E
231 All sizes are output in these units: human-(r)eadable with '<'
232 rounding indicator, (h)uman-readable, (b)ytes, (s)ectors,
233 (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes,
234 (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead
235 of 1024. Custom units can be specified, e.g. --units 3M.
236 --unquoted
238 When used with --nameprefixes, output values in the field=value
239 pairs are not quoted.
240 -v|--verbose ...
242 Set verbose level. Repeat from 1 to 4 times to increase the
243 detail of messages sent to stdout and stderr.
244 --version
246 Display version information.
247 -y|--yes
249 Do not prompt for confirmation interactively but always assume
250 the answer yes. Use with extreme caution. (For automatic no,
251 see -qq.)
252
254 PV
255 Physical Volume name, a device path under /dev. For commands
256 managing physical extents, a PV positional arg generally accepts
257 a suffix indicating a range (or multiple ranges) of physical
258 extents (PEs). When the first PE is omitted, it defaults to the
259 start of the device, and when the last PE is omitted it defaults
260 to end. Start and end range (inclusive): PV[:PE-PE]... Start
261 and length range (counting from 0): PV[:PE+PE]...
262 Tag
264 Tag name. See lvm(8) for information about tag names and using
265 tags in place of a VG, LV or PV.
266 String
268 See the option description for information about the string con‐
269 tent.
270 Size[UNIT]
272 Size is an input number that accepts an optional unit. Input
273 units are always treated as base two values, regardless of capi‐
274 talization, e.g. 'k' and 'K' both refer to 1024. The default
275 input unit is specified by letter, followed by |UNIT. UNIT rep‐
276 resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
277 bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is
278 megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
279 e|E is exabytes. (This should not be confused with the output
280 control --units, where capital letters mean multiple of 1000.)
281
283 See lvm(8) for information about environment variables used by lvm.
284 For example, LVM_VG_NAME can generally be substituted for a required VG
285 parameter.
286
288 The pv_attr bits are:
289 1 (d)uplicate, (a)llocatable, (u)sed
291 2 e(x)ported
293 3 (m)issing
