pvdisplay 显示 PV 的属性，例如大小、物理扩展区大小、VG 描述符区域已用空间等。
pvs 命令 是一个首选替代方案，它显示相同的信息，甚至更多，并且使用更紧凑且可配置的输出格式。

--aligned Use with --separator to align the output columns -a|--all Show information about devices that have not been initial‐ ized by LVM, i.e. they are not PVs. --binary Use binary values "0" or "1" instead of descriptive literal values for columns that have exactly two valid values to report (not counting the "unknown" value which denotes that the value could not be determined). -c|--colon Generate colon separated output for easier parsing in scripts or programs. Also see vgs(8) which provides con‐ siderably more control over the output. -C|--columns Display output in columns, the equivalent of vgs(8). Op‐ tions listed are the same as options given in vgs(8). --commandprofile String The command profile to use for command configuration. See lvm.conf(5) for more information about profiles. --config String Config settings for the command. These override lvm.conf(5) settings. The String arg uses the same format as lvm.conf(5), or may use section/field syntax. See lvm.conf(5) for more information about config. --configreport log|vg|lv|pv|pvseg|seg See lvmreport(7). -d|--debug ... Set debug level. Repeat from 1 to 6 times to increase the detail of messages sent to the log file and/or syslog (if configured). --devices PV Devices that the command can use. This option can be re‐ peated or accepts a comma separated list of devices. This overrides the devices file. --devicesfile String A file listing devices that LVM should use. The file must exist in /etc/lvm/devices/ and is managed with the lvmdevices(8) command. This overrides the lvm.conf(5) de‐ vices/devicesfile and devices/use_devicesfile settings. --driverloaded y|n If set to no, the command will not attempt to use device- mapper. For testing and debugging. --foreign Report/display foreign VGs that would otherwise be skipped. See lvmsystemid(7) for more information about foreign VGs. -h|--help Display help text. --ignorelockingfailure Allows a command to continue with read-only metadata opera‐ tions after locking failures. --journal String Record information in the systemd journal. This informa‐ tion is in addition to information enabled by the lvm.conf log/journal setting. command: record information about the command. output: record the default command output. de‐ bug: record full command debugging. --lockopt String Used to pass options for special cases to lvmlockd. See lvmlockd(8) for more information. --logonly Suppress command report and display only log report. --longhelp Display long help text. -m|--maps Display the mapping of physical extents to LVs and logical extents. --noheadings Suppress the headings line that is normally the first line of output. Useful if grepping the output. --nohints Do not use the hints file to locate devices for PVs. A com‐ mand may read more devices to find PVs when hints are not used. The command will still perform standard hint file in‐ validation where appropriate. --nolocking Disable locking. --nosuffix Suppress the suffix on output sizes. Use with --units (ex‐ cept h and H) if processing the output. -o|--options String Comma-separated, ordered list of fields to display in columns. String arg syntax is: [+|-|#]Field1[,Field2 ...] The prefix + will append the specified fields to the de‐ fault fields, - will remove the specified fields from the default fields, and # will compact specified fields (remov‐ ing them when empty for all rows.) Use -o help to view the list of all available fields. Use separate lists of fields to add, remove or compact by repeating the -o option: -o+field1,field2 -o-field3,field4 -o#field5. These lists are evaluated from left to right. Use field name lv_all to view all LV fields, vg_all all VG fields, pv_all all PV fields, pvseg_all all PV segment fields, seg_all all LV segment fields, and pvseg_all all PV segment columns. See the lvm.conf(5) report section for more config options. See lvmreport(7) for more information about reporting. --profile String An alias for --commandprofile or --metadataprofile, depend‐ ing on the command. -q|--quiet ... Suppress output and log messages. Overrides --debug and --verbose. Repeat once to also suppress any prompts with answer 'no'. --readonly Run the command in a special read-only mode which will read on-disk metadata without needing to take any locks. This can be used to peek inside metadata used by a virtual ma‐ chine image while the virtual machine is running. No at‐ tempt will be made to communicate with the device-mapper kernel driver, so this option is unable to report whether or not LVs are actually in use. -S|--select String Select objects for processing and reporting based on speci‐ fied criteria. The criteria syntax is described by --se‐ lect help and lvmreport(7). For reporting commands, one row is displayed for each object matching the criteria. See --options help for selectable object fields. Rows can be displayed with an additional "selected" field (-o se‐ lected) showing 1 if the row matches the selection and 0 otherwise. For non-reporting commands which process LVM entities, the selection is used to choose items to process. --separator String String to use to separate each column. Useful if grepping the output. --shared Report/display shared VGs that would otherwise be skipped when lvmlockd is not being used on the host. See lvmlockd(8) for more information about shared VGs. -s|--short Only display the size of the given PVs. -O|--sort String Comma-separated ordered list of columns to sort by. Re‐ places the default selection. Precede any column with - for a reverse sort on that column. -t|--test Run in test mode. Commands will not update metadata. This is implemented by disabling all metadata writing but never‐ theless returning success to the calling function. This may lead to unusual error messages in multi-stage operations if a tool relies on reading back metadata it believes has changed but hasn't. --unbuffered Produce output immediately without sorting or aligning the columns properly. --units [Number]r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E All sizes are output in these units: human-(r)eadable with '<' rounding indicator, (h)uman-readable, (b)ytes, (s)ec‐ tors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes, (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead of 1024. Custom units can be speci‐ fied, e.g. --units 3M. -v|--verbose ... Set verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and stderr. --version Display version information. -y|--yes Do not prompt for confirmation interactively but always as‐ sume the answer yes. Use with extreme caution. (For auto‐ matic no, see -qq.)
