hi,

refer to this doc on LVM commands:

http://docs.hp.com/en/B2355-60127/lvm.7.html

for vgdisplay:

http://docs.hp.com/en/B2355-60127/vgdisplay.1M.html

for pvdisplay:

http://docs.hp.com/en/B2355-60127/pvdisplay.1M.html

"man pvdisplay" and "man vgdisplay" will give u similar reply.


regards.
(p.s. please remember to assign points.)

Hi,

PE = Physical Extent

It is the minimum unit in which the disk has been divided into.

MAX_PV is the Maximum no. of Physical Volumes allowed in that Volume group. This can be defined at the time of creating the VG.

Free PV

This paratemeter should be Free PE instead and is the no. of Free Physical extents on the disk. FreePE multiplied by the PE size will give you the total free space on the disk.

HTH,
Devender

Hello,

As the name suggests, pvdisplay is used get information about Physical Volumes and vgdisplay is used for getting "Volume Group" information.

# man lvdiaplay and vgdisplay should give information about PE and PV.

Cur LV 1 (current lvols in VG)
Open LV 1 (open lvols ie lvols in use)
Max PV 32 (max physical
volumes that can be configured in the VG)
Cur PV 2 (current PV's in the VG)
Act PV 2 (currently active physical volumes in VG)
Max PE per PV 1078 (max physical extents per physical volumes)
VGDA 4 (Volume group data area there are 4)
PE Size (Mbytes) 8 (physical extent size this is the smallest physical partition on disk)
Total PE 2156 (total physical extents in the VG)
Alloc PE 2000 (physical extents allocated ie as parts of lvols)
