vgdisplay - display attributes of volume groups SYNOPSIS
vgdisplay [-A|--activevolumegroups] [-c|--colon|-s|--short|-v|--verbose] [-d|--debug] [-h|--help] [--ignorelockingfailure] [--nosuffix] [-P|--partial] [--unitshHbBsSkKmMgGtTpPeE] [--version] [VolumeGroupName[VolumeGroupName...]] vgdisplay --columns | -C [--aligned][-d|--debug][-h|-?|--help] [--ignorelockingfailure][--noheadings][--nosuffix] [-o|--options[+]Field[,Field]] [-O|--sort[+|-]Key1[,[+|-]Key2[,...]]] [-P|--partial] [--separatorSeparator] [--unbuffered] [--unitshHbB- sSkKmMgGtTpPeE] [-v|--verbose] [--version] [VolumeGroupName[VolumeGroupName...]] DESCRIPTION
vgdisplay allows you to see the attributes of VolumeGroupName (or all volume groups if none is given) with it's physical and logical vol- umes and their sizes etc. vgs (8) is an alternative that provides the same information in the style of ps (1). OPTIONS
See lvm for common options and vgs for options given with --columns. -A, --activevolumegroups Only select the active volume groups. -c, --colon Generate colon separated output for easier parsing in scripts or programs. N.B. vgs (8) provides considerably more control over the output. The values are: 1 volume group name 2 volume group access 3 volume group status 4 internal volume group number 5 maximum number of logical volumes 6 current number of logical volumes 7 open count of all logical volumes in this volume group 8 maximum logical volume size 9 maximum number of physical volumes 10 current number of physical volumes 11 actual number of physical volumes 12 size of volume group in kilobytes 13 physical extent size 14 total number of physical extents for this volume group 15 allocated number of physical extents for this volume group 16 free number of physical extents for this volume group 17 uuid of volume group -s, --short Give a short listing showing the existence of volume groups. -v, --verbose Display verbose information containing long listings of physical and logical volumes. If given twice, also display verbose runtime information of vgdisplay's activities. --version Display version and exit successfully. --columns|-C Display output in columns, the equivalent of vgs. Options listed are the same as options given in vgs (8). SEE ALSO
