NAME

vgdisplay - display information about LVM volume groups

SYNOPSIS

/usr/sbin/vgdisplay

[-F][-v][vg_name...]

/usr/sbin/vgdisplay

[-F][-v

][-V vg_vers | vg_name ...]

Remarks

If a combination of volume groups version 1.0 and 2.0 or higher arguments are supplied, the arguments

may not be processed in the order they are listed on the command line.

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. If the volume group version

is speciﬁed, vgdisplay displays names and corresponding information for all volume groups belonging

to the speciﬁed volume group version.

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.

-V vg_vers Display volume group information for all volume groups corresponding to the volume

group version vg_vers .

-F Produce a compact listing of ﬁelds described in Compact Listing (-F Option) . The out-

put 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. If the volume group is activated using -l option of the

vgchange command, its state is displayed as

available/inactive.

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.

Cur Snapshot LV Current number of snapshot logical volumes in the volume group.

Note that this is is only displayed for volume group 2.2 or higher. See

lvm(7) for information about snap logical volumes.

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.

DESCRIPTION The vgdisplay command displays information about volume groups.

vgdisplay(1M) vgdisplay(1M) VGDA Number of Volume Group Descriptor Areas within the volume group. PE Size Size of each physical extent in Megabytes. Unshare Unit Size Size of the unshare unit, in kilobytes. Note that this field is only displayed for volume group version 2.2 or higher. 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.
PAGE 3
vgdisplay(1M) vgdisplay(1M) Information about logical volumes belonging to vg_name : LV Name The block device path name of a logical volume in the volume group. LV Status State of the logical volume: available/stale Logical volume available but contains physical extents that are not current. available/syncd Logical volume available with no stale extents.

vgdisplay(1M) vgdisplay(1M) LV Size (Megabytes) Size of the logical volume. Current LE Number of logical extents in the logical volume. Allocated PE Number of physical extents used by the logical volume. Pre-allocated LE Number of pre-allocated logical extents in the logical volume. Current pre-allocated LE Number of logical extents that are pre-allocated, currently in the logical volume. Unshared LE Number of logical extents that are allocated (unshared) in the logical volume.
PAGE 5
vgdisplay(1M) Free PE vgdisplay(1M) Number of free physical extents on the physical volume. Current pre-allocated PE Number of pre-allocated physical extents on the physical volume. Note that this field is only displayed for volume group version 2.2 or higher. Spared from PV If the physical volume represents an active spare, this field will show the name of the failed physical volume whose data now resides on this spare.
