[ovirt-users] [Ovirt 4.0] Multiple cluster and multiple storage possible ?

[Fred Rolland]

Hi,

Storage Domains are DC entities and are not related to clusters.
Every hosts in the DC should be able to access the Storage Domain.
Once the SD is first created on one of the hosts, all the other host are
trying to connect also.

Can you mount manually from host2 ?
It maybe a firewall/network issue.
