Thanks for that info, Marcus.
By the way, I wanted to see if I could attach my volume to a VM in the
Stopped State.
The attach logic didn't trigger any exceptions; however, when I started the
VM, I received an Insufficient Capacity exception.
If I detach the volume and then start the VM, the VM starts just fine.
I noticed a problem here (in StoragePoolHostDaoImpl):
@Override
public StoragePoolHostVO findByPoolHost(long poolId, long hostId) {
SearchCriteria<StoragePoolHostVO> sc = PoolHostSearch.create();
sc.setParameters("pool_id", poolId);
sc.setParameters("host_id", hostId);
return findOneIncludingRemovedBy(sc);
}
The findOneIncludingRemovedBy method returns null (the poolId is my storage
pool's ID and the hostId is the expected host ID).
I'm not sure what this method is trying to do.
I looked in the storage_pool_host_ref table (is that the correct table?)
and it only has one row, which maps the local storage pool of the KVM host
to the KVM host (which explains why no match is found for my situation).
Do you understand what this logic is trying to do?
Thanks!
