Even we tried to increase with 1 PE, it is not extending.

lvextend -L  150016 /dev/vgprod1/sldapplv /dev/dsk/c10t0d0 /dev/dsk/c10t0d1 /dev/dsk/c10t0d2 /dev/dsk/c10t0d3 /dev/dsk/c12t0d0 /dev/dsk/c12t0d1 /dev/dsk/c12t0d2 /dev/dsk/c12t0d3

lvextend: Not enough free physical extents available.

Logical volume "/dev/vgprod1/sldapplv" could not be extended.

On Host abcd:

/etc/lvmpvg file is of 0 byte, which is not contaning any entry of PVG group

On Failover host xyz:

/etc/lvmpvg contains entry of few PVG group, but not of above all disk.

Please suggest where would be the mistake?

[Torsten.]

Because the allocation is pvg-strict I would first create a lvmpvg file that matches the current configuration, then do

lvextend -L  150016 /dev/vgprod1/sldapplv

Hi Torsten,

I had created the lvmpvg file on hostA and extended the Logical Volume, do I still need to created the relavant lvmpvg file entry on HostB.

[Torsten. · Accepted solution]

No need, but good practice.

[Patrick Wallek]

If you don't care about the PVG-strict allocation that can be changed with the 'lvchange' command and the '-s' option.

lvchange -s y /dev/vgprod1/sldapplv

will change it so it is just a 'strict' allocation policy rather than PVG-strict.

I agree that since it was PVG-strict the best solution is to create the /etc/lvmpvg file.

[Torsten.]

but since this is distributed AND mirrored, you should NOT change anything!
