[ovirt-users] Hosted engine on iscsi storage

[Darran Carey]

Hi All,

I am trying to install the hosted engine on an iscsi target but get the 
following error:

[root at virt-host01 ~]# hosted-engine --deploy
...
           --== STORAGE CONFIGURATION ==--

           During customization use CTRL-D to abort.

The relevant excerpt from the log file is:

This is on CentOS 7 with ovirt 3.6.
selinux is disabled.

I can mount the iscsi target fine using iscsiadm or the Dell Equallogic 
Host Integration Toolkit commands.

I think the first problem is the call to self.cli.getDeviceList in 
blockd.py is returning an empty list, but I don't know what that 
function is actually doing.

Has anyone experienced similar behaviour or has any suggestions as to 
what I should check next?

Thanks,
Darran.
