How to check if a VG is contiguous or not

[dictum9]

I am trying to extend an LV in a VG from 800GB to 1000GB, I need about 200GB.

I have 1000GB free yet the error says "not enough physical extents".

I suspect this may be due to the data allocation policy - contiguous or not.

1) How do I check the data allocatoin policy of a particular volume group?

2) How do I create a new volume group with non-contiguous data allocation poliicy?

3) Can I bypass data allocatio policy by specifically  listing the disks I am adding when doing the lvextend? Usually I've run lvextend without specifiying the disks but I understand you can explicitly list the disks you want to extend to and will that override the error I am getting?

this is on 11.31 with vg1.0

try

lvdisplay -v
for the lvol in question
