NAME

pvdisplay − Displays information about one or more physical volumes within a volume group

SYNOPSIS

/usr/sbin/pvdisplay [−v] PhysicalVolumePath ... 

DESCRIPTION

The pvdisplay command displays information about the physical volume(s) specified with the PhysicalVolumePath parameter.  If you use the −v (verbose) flag, the program displays a map of the logical extents that correspond to the physical extents of each physical volume. 

If you use the pvdisplay command without any flags, the program displays the characteristics of each physical volume that you specified with the PhysicalVolumePath parameter, namely:

PV NameThe name of the physical volume

VG NameThe name of the volume group

PV StatusThe state of the physical volume: available or unavailable

AllocatableThe allocation permission for the physical volume

VGDAThe number of volume group descriptors on the physical volume

Cur LVThe number of logical volumes using the physical volume

PE SizeThe size of physical extents on the volume

Total PEThe total number of physical extents on the physical volume

Free PEThe number of free physical extents on the physical volume

Allocated PE
The number of physical extents on the physical volume that are allocated to logical volumes

Stale PEThe number of physical extents on the physical volume that are not current

FLAGS

−vLists additional information for each logical volume and for each physical extent on the physical volume.  Distribution of physical volume: lists the logical volumes that have extents allocated on PhysicalVolumePath:

LV NameThe name of the logical volume which has extents allocated on PhysicalVolumePath. 

LE of LVThe number of logical extents within the logical volume that are contained on this physical volume. 

PE for LVThe number of physical extents within the logical volume that are contained on this physical volume. 

Physical extents:  displays the following information for each physical extent:

PEThe physical extent number. 

StatusThe state of the physical extent: free, current, or stale. 

LVThe name of the logical volume to which the extent is allocated. 

LEThe index of the logical extent to which the physical extent is allocated.
