NAME
vgdisplay - display information about LVM volume groups
SYNOPSIS
/usr/sbin/vgdisplay
[-F][-v][vg_name...]
DESCRIPTION
The
vgdisplay command displays information about volume groups. For each vg_name specified,
vgdisplay displays information for that volume group only. If no vg_name is specified,
vgdisplay
displays names and corresponding information for all defined volume groups.
The volume group must be activated (see vgchange(1M)) before it can be displayed.
Options and Arguments
vgdisplay recognizes the following options and arguments:
vg_name The path name of the volume group, for example,
/dev/vg00.
-F Produce a compact listing of fields described in Compact Listing (-F Option). The output is
a list of colon separated fields formatted as key
=value[,value...].
-v For each volume group, display additional information about logical volumes, physical
volumes, and physical volume groups.
Display Without -v Option
If you omit the -v option, only the following information is displayed:
--- Volume groups ---
VG Name
The path name of the volume group.
VG Write Access Current access mode and quiesce mode of the volume group. The access
mode is either read/write or read-only. If the volume group is
quiesced, the quiesce mode is displayed on the same line. The quiesce
mode is either read/write-quiesced
or write-quiesced.
VG Status State of the volume group: always available, as after a
vgchange -a y command, since deactivated volume groups are not
displayed.
Max LV Maximum number of logical volumes allowed in the volume group.
Cur LV Current number of logical volumes in the volume group.
Open LV Number of logical volumes currently open in the volume group.
Max PV Maximum number of physical volumes allowed in the volume group.
Cur PV Current number of physical volumes in the volume group.
Act PV Number of physical volumes that are currently active.
Max PE per PV Maximum number (limit) of physical extents that can be allocated from
any of the physical volumes in the volume group.
VGDA Number of Volume Group Descriptor Areas within the volume group.
PE Size Size of each physical extent in Megabytes.
Total PE Total number of physical extents within the volume group: the sum of
the number of physical extents belonging to each available physical
volume in the volume group. (This does not include physical extents
belonging to stand-by spare physical volumes; presence of these is only
possible if you are using mirrored disks -- see below).
Alloc PE Number of physical extents currently allocated to logical volumes.
Free PE Number of physical extents not allocated (not including physical extents
belonging to stand-by spares).
Total PVG Total number of physical volume groups within the volume group.
