how to check the size of vg00

[Kryno Bosman]

# vgdisplay -v vg00|awk '/Total PE/ {print $3 * 4,"MByte."}'
34720 MByte.
17360 MByte.
17360 MByte.
#

First entry is the total size of vg00. The other two entries are the size of disks in vg00.

Hi Karthick

VG Name /dev/vg00
VG Write Access read/write
VG Status available
Max LV 255
Cur LV 12
Open LV 12
Max PV 16
Cur PV 2
Act PV 2
Max PE per PV 4350
VGDA 4
PE Size (Mbytes) 8
Total PE 8680
Alloc PE 8680
Free PE 0
Total PVG 0
Total Spare PVs 0
Total Spare PVs in use 0

Free PE is 0 means that your vg00 used all available.
The size of VG00 is Total PE *PE Size (Mbytes)=8680*8MB.
Pls assign points to what you think it is usefull for you.

Hi,

To extend the root file system, you can use one of the following method :

1. re-install the OS
2. using Ignite/UX software

It's very easy if you using method #2, just do backup the OS using make_tape_recovery command > verify the backup > boot from the tape > interupt the process > increase the file system

The Ignite/UX is a freeware, can be download from this url :

http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=IGNITEUXB

But since you dont have any free PE on your vg00, you either :

1. need to have a space from other file system OR;
2. add another disk on vg00, so there will be free PE again on your vg00 OR;
3. do a housekeeping on your root file system.

Hope this information can help you.

Cheers,
AW

Best way to increase root file system - with ignite.

That said - it is possible to do it under certain circumstances when you boot into lvm maintenance mode:

On one of my systems, I was able to do this - as lvol3 was unused and lvol4 was root:

Increase /stand:

The procedure listed is as follows -

/stand is only 84 MB on my server, for 11i, needs to be at least 112 MB.

Boot your machine in LVM maintenance mode
(hpux -lm at ISL>)

#
# vgchange -a y /dev/vg00
# lvrmboot -r /dev/vg00
# lvremove /dev/vg00/lvol3
# lvremove /dev/vg00/lvol2
# lvextend -L 256 /dev/vg00/lvol1
# extendfs /dev/vg00/rlvol1
# lvcreate -L 1024 -C y -r n -n lvol2 /dev/vg00
# lvlnboot -b /dev/vg00/lvol1
# lvlnboot -r /dev/vg00/lvol4
# lvlnboot -s /dev/vg00/lvol2
# lvlnboot -d /dev/vg00/lvol2
# lvlnboot -R
# reboot -r

Note: lvol3 is unused, lvol4 is /
