Lvextend error

jmckinzie — Fri, 01 Jun 2007 13:36:50 GMT

I am receiving this error when trying to extend my lv.

# lvextend -m 1 /dev/vg_ora2/db newhit

LVM: Unable to map all the LEs to unique PEs.
lvextend: The LVM device driver could not extend the logical volume.

I have the new SAN disks added to the VG and I have successfully mirrored two other lvols.

Any ideas?

-TIA

What is newhit? Is it a PV or something else. It is not clear so could you provide more details.

thanks

i am using pvg strict mirroring as to not allow mirroring to devices that reside on the same controller.

New hit is the name of the physical volume group that I assignmed to my new disks.

Thanks,

Hi Jody:

For 11.11, patch PHKL_35970 addresses this defect.

THis is on hp-ux 11.00.

Why will it work for the other lvols?
Do you know how to fix it for 11.00?

The fix would be to take out some PVs out of the newhit PVG so that the total number of PEs within that PVG falls to below 64K.

Is there a way to fix this in 11.00?

Hi Jody:

I didn't see any 11.0 patches. More importantly, 11.0 fell out-of-support in December 2006, so I think that you are going to have to adjust your configuration accordingly (i.e. without the help of any patch(es)).

I am confused....
How do i fix this? i am already mirroring two other lvols using pvg-strict.

Can i remove disks from pvg without reducing the vg?

So, the disk would still be on the other lvols?

created pvg strict volume group by figuring out the correct syntax.
