How to convert Strict/Distributed volumes to normal.
Some times the HP engineers will create the volumes with strict / distributed instead of doing striping in the volume manager. We may not have enough disks to extend the volumes, in that case we can remove the strict allocation and make the volume as normal volume.
To turn off the Distributed allocation policy:
# lvchange -D n /dev/vg02/lvol1
That can be done online. After that you should be able to do your lvextend.
Change the allocation policy of a logical volume to nonstrict:
#lvchange -s n /dev/vg01/lvol7
