For what I saw the issue is not related to the storage but to the network.
ovirt-hosted-engine-setup uses the jsonrpc client, instead the code
from ovirt-hosted-engine-ha still uses the xmlrpc client somewhere and
this happens also when the setup asks to create the lockspace volume.
It seams that in your case the xmlrpc client could not connect vdsm on
the localhost.
It could be somehow related to:
https://bugzilla.redhat.com/1358530

Can you please try executing
 sudo vdsClient -s 0 getVdsCaps
on that host?
