Putting a VG\ninto an unusable, offline state can be useful when doing things like moving a VG's disks to\nanother system. Exporting a VG provides some protection from its LVs being accidentally\nused, or being used by an automated system before it's ready.\n\nA VG cannot be exported until all of its LVs are inactive.\n\nLVM commands will ignore an exported VG or report an error if a command tries to use it.\n\nFor an exported VG, the vgs command will display attribute, and the pvs command will display\nattribute. Both vgs and pvs will display report field.\n\nvgexport clears the VG system ID, and vgimport sets the VG system ID to match the host run‐\nning vgimport (if the host has a system ID).\n\n### USAGE\n\nExport specified VGs.\n\nvgexport VG|Tag|Select ...\n[ -S|--select String ]\n[ COMMONOPTIONS ]\n\nExport all VGs.\n\nvgexport -a|--all\n[ COMMONOPTIONS ]\n\nCommon options for command:\n[ --reportformat basic|json ]\n\nCommon options for lvm:\n[ -d|--debug ]\n[ -h|--help ]\n[ -q|--quiet ]\n[ -t|--test ]\n[ -v|--verbose ]\n[ -y|--yes ]\n[ --commandprofile String ]\n[ --config String ]\n[ --driverloaded y|n ]\n[ --lockopt String ]\n[ --longhelp ]\n[ --nolocking ]\n[ --profile String ]\n[ --version ]\n\n### OPTIONS\n\n#### -a --all\n\n--commandprofile String\nThe command profile to use for command configuration. 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#### -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#### -h --help\n\nDisplay help text.\n\n--lockopt String\nUsed to pass options for special cases to lvmlockd. See lvmlockd(8) for more informa‐\ntion.\n\n#### --longhelp\n\nDisplay long help text.\n\n#### --nolocking\n\nDisable locking.\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--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#### -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#### -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#### -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\nVG\nVolume Group name. See lvm(8) for valid names.\n\nTag\nTag name. See lvm(8) for information about tag names and using tags in place of a VG,\nLV or PV.\n\nSelect\nSelect indicates that a required positional parameter can be omitted if the --select\noption is used. No arg appears in this position.\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### 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.
