See lvm.conf(5) for more infor‐\nmation about profiles.\n\n--config String\nConfig settings for the command. These override lvm.conf settings.  The String arg\nuses the same format as lvm.conf, or may use section/field syntax.  See lvm.conf(5)\nfor more information about config.\n\n--configreport log|vg|lv|pv|pvseg|seg\nSee lvmreport(7).\n\n#### -d --debug\n\nSet debug level. Repeat from 1 to 6 times to increase the detail of messages sent to\nthe log file and/or syslog (if configured).\n\n--driverloaded y|n\nIf set to no, the command will not attempt to use device-mapper.  For testing and de‐\nbugging.\n\n#### --foreign\n\nReport/display foreign VGs that would otherwise be skipped.  See lvmsystemid(7) for\nmore information about foreign VGs.\n\n#### -h --help\n\nDisplay help text.\n\n#### --ignorelockingfailure\n\nAllows a command to continue with read-only metadata operations after locking fail‐\nures.\n\n--lockopt String\nUsed to pass options for special cases to lvmlockd.  See lvmlockd(8) for more informa‐\ntion.\n\n#### --logonly\n\nSuppress command report and display only log report.\n\n#### --longhelp\n\nDisplay long help text.\n\n#### --nameprefixes\n\nAdd an \"LVM2\" prefix plus the field name to the output. Useful with --noheadings to\nproduce a list of field=value pairs that can be used to set environment variables (for\nexample, in udev rules).\n\n#### --noheadings\n\nSuppress the headings line that is normally the first line of output.  Useful if grep‐\nping the output.\n\n#### --nolocking\n\nDisable locking.\n\n#### --nosuffix\n\nSuppress the suffix on output sizes. Use with --units (except h and H) if processing\nthe output.\n\n#### -o --options\n\nComma-separated, ordered list of fields to display in columns.  String arg syntax is:\n[+|-|#]Field1[,Field2 ...]  The prefix + will append the specified fields to the de‐\nfault fields, - will remove the specified fields from the default fields, and # will\ncompact specified fields (removing them when empty for all rows.)  Use -o help to view\nthe list of all available fields.  Use separate lists of fields to add, remove or com‐\npact by repeating the -o option: -o+field1,field2 -o-field3,field4 -o#field5.  These\nlists are evaluated from left to right.  Use field name lvall to view all LV fields,\nvgall all VG fields, pvall all PV fields, pvsegall all PV segment fields, segall\nall LV segment fields, and pvsegall all PV segment columns.  See the lvm.conf report\nsection for more config options.  See lvmreport(7) for more information about report‐\ning.\n\n--profile String\nAn alias for --commandprofile or --metadataprofile, depending on the command.\n\n#### -q --quiet\n\nSuppress output and log messages. Overrides --debug and --verbose.  Repeat once to\nalso suppress any prompts with answer 'no'.\n\n#### --readonly\n\nRun the command in a special read-only mode which will read on-disk metadata without\nneeding to take any locks. This can be used to peek inside metadata used by a virtual\nmachine image while the virtual machine is running. No attempt will be made to commu‐\nnicate with the device-mapper kernel driver, so this option is unable to report\nwhether or not LVs are actually in use.\n\n--reportformat basic|json\nOverrides current output format for reports which is defined globally by the re‐\nport/outputformat setting in lvm.conf.  basic is the original format with columns and\nrows.  If there is more than one report per command, each report is prefixed with the\nreport name for identification. json produces report output in JSON format. See lvmre‐‐\nport(7) for more information.\n\n#### --rows\n\nOutput columns as rows.\n\n#### --segments\n\nProduces one line of output for each contiguous allocation of space on each PV, show‐\ning the start (pvsegstart) and length (pvsegsize) in units of physical extents.\n\n#### -S --select\n\nSelect objects for processing and reporting based on specified criteria.  The criteria\nsyntax is described by --select help and lvmreport(7).  For reporting commands, one\nrow is displayed for each object matching the criteria.  See --options help for se‐\nlectable object fields.  Rows can be displayed with an additional \"selected\" field (-o\nselected) showing 1 if the row matches the selection and 0 otherwise.  For non-report‐\ning commands which process LVM entities, the selection is used to choose items to\nprocess.\n\n--separator String\nString to use to separate each column. Useful if grepping the output.\n\n#### --shared\n\nReport/display shared VGs that would otherwise be skipped when lvmlockd is not being\nused on the host.  See lvmlockd(8) for more information about shared VGs.\n\n#### -O --sort\n\nComma-separated ordered list of columns to sort by. Replaces the default selection.\nPrecede any column with - for a reverse sort on that column.\n\n#### -t --test\n\nRun in test mode. Commands will not update metadata.  This is implemented by disabling\nall metadata writing but nevertheless returning success to the calling function. This\nmay lead to unusual error messages in multi-stage operations if a tool relies on read‐\ning back metadata it believes has changed but hasn't.\n\n#### --unbuffered\n\nProduce output immediately without sorting or aligning the columns properly.\n\n--units r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E\nAll sizes are output in these units: human-(r)eadable with '<' rounding indicator,\n(h)uman-readable, (b)ytes, (s)ectors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)er‐\nabytes, (p)etabytes, (e)xabytes.  Capitalise to use multiples of 1000 (S.I.) instead\nof 1024.  Custom units can be specified, e.g. --units 3M.\n\n#### --unquoted\n\nWhen used with --nameprefixes, output values in the field=value pairs are not quoted.\n\n#### -v --verbose\n\nSet verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to\nstdout and stderr.\n\n#### --version\n\nDisplay version information.\n\n#### -y --yes\n\nDo not prompt for confirmation interactively but always assume the answer yes. Use\nwith extreme caution.  (For automatic no, see -qq.)\n\n### VARIABLES\n\nPV\nPhysical Volume name, a device path under /dev.  For commands  managing  physical  ex‐\ntents,  a PV positional arg generally accepts a suffix indicating a range (or multiple\nranges) of physical extents (PEs). When the first PE is omitted, it  defaults  to  the\nstart  of  the  device, and when the last PE is omitted it defaults to end.  Start and\nend range (inclusive): PV[:PE-PE]...   Start  and  length  range  (counting  from  0):\nPV[:PE+PE]...\n\nTag\nTag name.  See lvm(8) for information about tag names and using tags in place of a VG,\nLV or PV.\n\nString\nSee the option description for information about the string content.\n\nSize[UNIT]\nSize is an input number that accepts an optional unit.  Input units are always treated\nas base two values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024.\nThe default input unit is specified by letter, followed  by  |UNIT.   UNIT  represents\nother  possible  input  units:  bBsSkKmMgGtTpPeE.  b|B is bytes, s|S is sectors of 512\nbytes, 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\nshould  not  be  confused  with the output control --units, where capital letters mean\nmultiple of 1000.)\n\n### ENVIRONMENT VARIABLES\n\nSee lvm(8) for information about environment variables used by lvm.  For example, LVMVGNAME\ncan generally be substituted for a required VG parameter.\n\n### NOTES\n\nThe pvattr bits are:\n\n1  (d)uplicate, (a)llocatable, (u)sed\n\n2  e(x)ported\n\n3  (m)issing\n\n### SEE ALSO\n\nlvm(8) lvm.conf(5) lvmconfig(8)\n\npvchange(8)  pvck(8)  pvcreate(8)  pvdisplay(8) pvmove(8) pvremove(8) pvresize(8) pvs(8) pvs‐‐\ncan(8)\n\nvgcfgbackup(8) vgcfgrestore(8) vgchange(8) vgck(8) vgcreate(8) vgconvert(8) vgdisplay(8)  vg‐‐\nexport(8)  vgextend(8) vgimport(8) vgimportclone(8) vgmerge(8) vgmknodes(8) vgreduce(8) vgre‐‐\nmove(8) vgrename(8) vgs(8) vgscan(8) vgsplit(8)\n\nlvcreate(8) lvchange(8) lvconvert(8) lvdisplay(8) lvextend(8) lvreduce(8)  lvremove(8)  lvre‐‐\nname(8) lvresize(8) lvs(8) lvscan(8)\n\nlvm-fullreport(8) lvm-lvpoll(8) lvm2-activation-generator(8) blkdeactivate(8) lvmdump(8)\n\ndmeventd(8) lvmpolld(8) lvmlockd(8) lvmlockctl(8) cmirrord(8) lvmdbusd(8)\n\nlvmsystemid(7) lvmreport(7) lvmraid(7) lvmthin(7) lvmcache(7)\n\n\n\nRed Hat, Inc.
