61 --aligned
62 Use with --separator to align the output columns
63 -a|--all
65 Show information about devices that have not been initialized by
66 LVM, i.e. they are not PVs.
67 --binary
69 Use binary values "0" or "1" instead of descriptive literal val‐
70 ues for columns that have exactly two valid values to report
71 (not counting the "unknown" value which denotes that the value
72 could not be determined).
73 --commandprofile String
75 The command profile to use for command configuration. See
76 lvm.conf(5) for more information about profiles.
77 --config String
79 Config settings for the command. These override lvm.conf set‐
80 tings. The String arg uses the same format as lvm.conf, or may
81 use section/field syntax. See lvm.conf(5) for more information
82 about config.
83 --configreport log|vg|lv|pv|pvseg|seg
85 See lvmreport(7).
86 -d|--debug ...
88 Set debug level. Repeat from 1 to 6 times to increase the detail
89 of messages sent to the log file and/or syslog (if configured).
90 --driverloaded y|n
92 If set to no, the command will not attempt to use device-mapper.
93 For testing and debugging.
94 --foreign
96 Report/display foreign VGs that would otherwise be skipped. See
97 lvmsystemid(7) for more information about foreign VGs.
98 -h|--help
100 Display help text.
101 --ignorelockingfailure
103 Allows a command to continue with read-only metadata operations
104 after locking failures.
105 --lockopt String
107 Used to pass options for special cases to lvmlockd. See lvm‐
108 lockd(8) for more information.
109 --logonly
111 Suppress command report and display only log report.
112 --longhelp
114 Display long help text.
115 --nameprefixes
117 Add an "LVM2_" prefix plus the field name to the output. Useful
118 with --noheadings to produce a list of field=value pairs that
119 can be used to set environment variables (for example, in udev
120 rules).
121 --noheadings
123 Suppress the headings line that is normally the first line of
124 output. Useful if grepping the output.
125 --nolocking
127 Disable locking.
128 --nosuffix
130 Suppress the suffix on output sizes. Use with --units (except h
131 and H) if processing the output.
132 -o|--options String
134 Comma-separated, ordered list of fields to display in columns.
135 String arg syntax is: [+|-|#]Field1[,Field2 ...] The prefix +
136 will append the specified fields to the default fields, - will
137 remove the specified fields from the default fields, and # will
138 compact specified fields (removing them when empty for all
139 rows.) Use -o help to view the list of all available fields.
140 Use separate lists of fields to add, remove or compact by
141 repeating the -o option: -o+field1,field2 -o-field3,field4
142 -o#field5. These lists are evaluated from left to right. Use
143 field name lv_all to view all LV fields, vg_all all VG fields,
144 pv_all all PV fields, pvseg_all all PV segment fields, seg_all
145 all LV segment fields, and pvseg_all all PV segment columns.
146 See the lvm.conf report section for more config options. See
147 lvmreport(7) for more information about reporting.
148 --profile String
150 An alias for --commandprofile or --metadataprofile, depending on
151 the command.
152 -q|--quiet ...
154 Suppress output and log messages. Overrides --debug and --ver‐
155 bose. Repeat once to also suppress any prompts with answer
156 'no'.
157 --readonly
159 Run the command in a special read-only mode which will read on-
160 disk metadata without needing to take any locks. This can be
161 used to peek inside metadata used by a virtual machine image
162 while the virtual machine is running. No attempt will be made to
163 communicate with the device-mapper kernel driver, so this option
164 is unable to report whether or not LVs are actually in use.
165 --reportformat basic|json
167 Overrides current output format for reports which is defined
168 globally by the report/output_format setting in lvm.conf. basic
169 is the original format with columns and rows. If there is more
170 than one report per command, each report is prefixed with the
171 report name for identification. json produces report output in
172 JSON format. See lvmreport(7) for more information.
173 --rows
175 Output columns as rows.
176 --segments
178 Produces one line of output for each contiguous allocation of
179 space on each PV, showing the start (pvseg_start) and length
180 (pvseg_size) in units of physical extents.
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 PV
248 Physical Volume name, a device path under /dev. For commands
249 managing physical extents, a PV positional arg generally accepts
250 a suffix indicating a range (or multiple ranges) of physical
251 extents (PEs). When the first PE is omitted, it defaults to the
252 start of the device, and when the last PE is omitted it defaults
253 to end. Start and end range (inclusive): PV[:PE-PE]... Start
254 and length range (counting from 0): PV[:PE+PE]...
255 Tag
257 Tag name. See lvm(8) for information about tag names and using
258 tags in place of a VG, LV or PV.
259 String
261 See the option description for information about the string con‐
262 tent.
263 Size[UNIT]
265 Size is an input number that accepts an optional unit. Input
266 units are always treated as base two values, regardless of capi‐
267 talization, e.g. 'k' and 'K' both refer to 1024. The default
268 input unit is specified by letter, followed by |UNIT. UNIT rep‐
269 resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
270 bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is
271 megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
272 e|E is exabytes. (This should not be confused with the output
273 control --units, where capital letters mean multiple of 1000.)
274
276 See lvm(8) for information about environment variables used by lvm.
277 For example, LVM_VG_NAME can generally be substituted for a required VG
278 parameter.
279
281 The pv_attr bits are:
282 1 (d)uplicate, (a)llocatable, (u)sed
284 2 e(x)ported
286 3 (m)issing
