vgextend problem

Massimo_48 — Wed, 13 Oct 2004 09:39:58 GMT

Hi all,

I've a HP-UX 11i.
I've created a VG for OVPI installation.
when I've tried to execute the mirror between the first disk and another disk, I've this message:
vgextend /dev/vgovpi /dev/dsk/c4t3d0
vgextend: Couldn't install the physical volume "/dev/dsk/c4t3d0".
File too large

disk size 73 Gb
I've configred two filesystem on first disk
- 6Gb
- 61Gb

Any suggestion?

Thanks in advance

Hi,

run vgdisplay vg00 and check PE Size,
I think that you have to low value of PE Size.

Hi Massimo,

Did you run 'pvcreate' on this disk?.

Did you do a pvcreate.

pvcreate -f /dev/dsk/c4t3d0

then do

vgextend -f vg_name pv_name

Hope this helps

Hello Massimo,

run a vgdisplay vgovpi, and the look the PE size and the max PE per PV, maybe your vgovpi was created with disks smaller than the one you are triyng to include and it's too big for your vgovpi.

Regards

P.S: the solution is to create a nes vg and move all your data to this new vg.

hi,

vgovpi can handle only disk < 70004MB.
A 73GB disk cannot be used completely in the VG.

Thierry.

Yes seems there is a problem. You can use a 68GB drive and not 73GB.

You will wither have to form a new VG with this PV.
Do the backup of old VG to this new VG. might be using fbackup & frecover.
or cpio.
Then remove the old VG, and join the disk of old VG to new one. Or you may like to do the installation again if it is not time consuming and complicated.

Hope this helps
Thanks
Prashant

And why is -B?..

Just run 'pvcreate /dev/rdsk/c4t3d0'. Use '-f' if it gives you any problem.

Hi,

I think that you have to:
- configure new vg containing disk c4t3d0 but with greater PE size
- create lvols 1 i 2
- shutdown application
- copy data from vgovpi lvols to new lvols
- modify /etc/fstab with new vg name
- check aplication
- remove vgovpi
- extend new vg with disk of vgovpi
- mirror lvols

Regardless of the size of the disk, lvm 'should' allow you to add to the volume group after running pvcreate. Since your vg will only see a disk size of 68gb, lvm should be able to extend the disk in but give a warning that some disk space will be wasted (~5gb). I would try creating a new volume group with the 73gb disk. If that's successful, open a call with HP support to see if there's any known issues or patches which address the problem you're experiencing.

Best Regards,
Eric
