Hi:
I'm puzzled. We have a storage pool with co-location set on, yet after querying 
the volume usage table it suggest more than one node is stored on a given 
volume. Anyone hazard a guess as to why?

VOLUME_NAME     NODE_NAME       STGPOOL_NAME
000015  EZRSDBMS        NT3590BACK
000015  GIS     NT3590BACK
000015  HQMSTBDC01      NT3590BACK
000015  HQSMSMST01      NT3590BACK
000015  IIISDBMS        NT3590BACK
000015  NYCRESBDC       NT3590BACK
000015  PROXY   NT3590BACK
000015  TKCSCITRIX      NT3590BACK

Query that resulted in the above:

select distinct volume_name,node_name,stgpool_name from volumeusage where not 
stgpool_name='OFFSITEVOLS'

stg pool defs:
