PVS(8) System Manager's Manual PVS(8) NAME pvs - Display information about physical volumes SYNOPSIS pvs [ option_args ] [ position_args ] DESCRIPTION pvs produces formatted output about PVs. USAGE pvs [ -a|--all ] [ -o|--options String ] [ -S|--select String ] [ -O|--sort String ] [ --segments ] [ --aligned ] [ --binary ] [ --configreport log|vg|lv|pv|pvseg|seg ] [ --foreign ] [ --ignorelockingfailure ] [ --logonly ] [ --nameprefixes ] [ --noheadings ] [ --nosuffix ] [ --readonly ] [ --reportformat basic|json ] [ --rows ] [ --separator String ] [ --shared ] [ --unbuffered ] [ --units r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E ] [ --unquoted ] [ COMMON_OPTIONS ] [ PV|Tag ... ] Common options for lvm: [ -d|--debug ] [ -h|--help ] [ -q|--quiet ] [ -t|--test ] [ -v|--verbose ] [ -y|--yes ] [ --commandprofile String ] [ --config String ] [ --driverloaded y|n ] [ --lockopt String ] [ --longhelp ] [ --nolocking ] [ --profile String ] [ --version ] OPTIONS --aligned Use with --separator to align the output columns -a|--all Show information about devices that have not been initialized 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 de‐ notes that the value could not be determined). --commandprofile String The command profile to use for command configuration. See lvm.conf(5) for more infor‐ mation about profiles. --config String Config settings for the command. These override lvm.conf settings. The String arg uses the same format as lvm.conf, 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). --driverloaded y|n If set to no, the command will not attempt to use device-mapper. For testing and de‐ bugging. --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 operations after locking fail‐ ures. --lockopt String Used to pass options for special cases to lvmlockd. See lvmlockd(8) for more informa‐ tion. --logonly Suppress command report and display only log report. --longhelp Display long help text. --nameprefixes Add an "LVM2_" prefix plus the field name to the output. Useful with --noheadings to produce a list of field=value pairs that can be used to set environment variables (for example, in udev rules). --noheadings Suppress the headings line that is normally the first line of output. Useful if grep‐ ping the output. --nolocking Disable locking. --nosuffix Suppress the suffix on output sizes. Use with --units (except 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 (removing 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 com‐ pact 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 report section for more config options. See lvmreport(7) for more information about report‐ ing. --profile String An alias for --commandprofile or --metadataprofile, depending 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 machine image while the virtual machine is running. No attempt will be made to commu‐ nicate with the device-mapper kernel driver, so this option is unable to report whether or not LVs are actually in use. --reportformat basic|json Overrides current output format for reports which is defined globally by the re‐ port/output_format setting in lvm.conf. basic is the original format with columns and rows. If there is more than one report per command, each report is prefixed with the report name for identification. json produces report output in JSON format. See lvmre‐‐ port(7) for more information. --rows Output columns as rows. --segments Produces one line of output for each contiguous allocation of space on each PV, show‐ ing the start (pvseg_start) and length (pvseg_size) in units of physical extents. -S|--select String Select objects for processing and reporting based on specified criteria. The criteria syntax is described by --select help and lvmreport(7). For reporting commands, one row is displayed for each object matching the criteria. See --options help for se‐ lectable object fields. Rows can be displayed with an additional "selected" field (-o selected) showing 1 if the row matches the selection and 0 otherwise. For non-report‐ ing 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. -O|--sort String Comma-separated ordered list of columns to sort by. Replaces 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 nevertheless returning success to the calling function. This may lead to unusual error messages in multi-stage operations if a tool relies on read‐ ing back metadata it believes has changed but hasn't. --unbuffered Produce output immediately without sorting or aligning the columns properly. --units 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)ectors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)er‐ abytes, (p)etabytes, (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead of 1024. Custom units can be specified, e.g. --units 3M. --unquoted When used with --nameprefixes, output values in the field=value pairs are not quoted. -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 assume the answer yes. Use with extreme caution. (For automatic no, see -qq.) VARIABLES PV Physical Volume name, a device path under /dev. For commands managing physical ex‐ tents, a PV positional arg generally accepts a suffix indicating a range (or multiple ranges) of physical extents (PEs). When the first PE is omitted, it defaults to the start of the device, and when the last PE is omitted it defaults to end. Start and end range (inclusive): PV[:PE-PE]... Start and length range (counting from 0): PV[:PE+PE]... Tag Tag name. See lvm(8) for information about tag names and using tags in place of a VG, LV or PV. String See the option description for information about the string content. Size[UNIT] Size is an input number that accepts an optional unit. Input units are always treated as base two values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024. The default input unit is specified by letter, followed by |UNIT. UNIT represents other possible input units: bBsSkKmMgGtTpPeE. b|B is bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB, p|P is PiB, e|E is EiB. (This should not be confused with the output control --units, where capital letters mean multiple of 1000.) ENVIRONMENT VARIABLES See lvm(8) for information about environment variables used by lvm. For example, LVM_VG_NAME can generally be substituted for a required VG parameter. NOTES The pv_attr bits are: 1 (d)uplicate, (a)llocatable, (u)sed 2 e(x)ported 3 (m)issing SEE ALSO lvm(8) lvm.conf(5) lvmconfig(8) pvchange(8) pvck(8) pvcreate(8) pvdisplay(8) pvmove(8) pvremove(8) pvresize(8) pvs(8) pvs‐‐ can(8) vgcfgbackup(8) vgcfgrestore(8) vgchange(8) vgck(8) vgcreate(8) vgconvert(8) vgdisplay(8) vg‐‐ export(8) vgextend(8) vgimport(8) vgimportclone(8) vgmerge(8) vgmknodes(8) vgreduce(8) vgre‐‐ move(8) vgrename(8) vgs(8) vgscan(8) vgsplit(8) lvcreate(8) lvchange(8) lvconvert(8) lvdisplay(8) lvextend(8) lvreduce(8) lvremove(8) lvre‐‐ name(8) lvresize(8) lvs(8) lvscan(8) lvm-fullreport(8) lvm-lvpoll(8) lvm2-activation-generator(8) blkdeactivate(8) lvmdump(8) dmeventd(8) lvmpolld(8) lvmlockd(8) lvmlockctl(8) cmirrord(8) lvmdbusd(8) lvmsystemid(7) lvmreport(7) lvmraid(7) lvmthin(7) lvmcache(7) Red Hat, Inc.
