Increasing Volume group size

[Randy Durden]

Is there anyway to turn off the strict allocation so I can extend this volume?

"you are going to have to recreate (backup, lvremove, lvcreaate, restore)"

Disregard that last answer and see the lvchange command.

Can you give me the format I should use for the lvchange command?

[Pete Randall]

lvchange -C n /dev/vg_audev_backup/audev_backup

I now have it as a non-strict allocation. I used lvchange -s n . For some reason it is not seeing the new 60G sized LUN.
When I run the lvextend now it says

lvextend: Not enough free physical extents available.
Logical volume "/dev/vg_audev_backup/audev_backup" could not be extended.

[Pete Randall]

The "strict" allocation policy, or lack thereof, only applies to mirrored LVs. You need to change the contiguous attribute with the -C switch.

I'm sorry I forgot to post that I did run it with the -C. New lvdisplay below.

--- Logical volumes ---
LV Name /dev/vg_audev_backup/audev_backup
VG Name /dev/vg_audev_backup
LV Permission read/write
LV Status available/syncd
Mirror copies 0
Consistency Recovery MWC
Schedule parallel

Can you post the exact lvextend command you're using?

lvextend -L 60000 /dev/vg_audev_backup/audev_backup
