Hello,

I'm brand new to Ovirt and trying to get my Hosted Engine setup configured with ISCSI storage. I have ~8TB usable storage available on an LVM partition. This storage is on the same server that is hosting the ovirt engine virtual machine. After I use the discovery/sendtargets command via Centos 7 engine vm, it shows the correct IQN. When I use ovirt's storage discovery in GUI, I can see the storage IQN just fine as well, but when I try to connect to it, I get the following:

"Error while executing action: Failed to login to iSCSI node due to authorization failure"

Could you please attach vdsm logs from the host for the relevant time frame?

Is NFS recommended instead when trying to connect the storage from server host to Ovirt Engine VM? There is nothing in this storage domain yet. This is a brand new setup.

NFS consumed in loop-back could be problematic, iSCSI and gluster looks as better options if you want to have everything on a single machine.

One other thing to note...I have iscsi storage working with a NAS for my ISO storage domain. I don't want to use the NAS for the virtual machine storage domain. What's so different about the Ovirt Engine vm?

The hosted-engine VM is a special VM since it's running the engine that manages your system. It should have its own storage domain since we are preventing a few actions there to avoid blocking the engine while it's working so, in order to avoid preventing some flows on regular VMs, the hosted-engine VM and other VMs should be into distinct storage domains.

Any help would be much appreciated. Please let me know If I'm taking the wrong approach here, or I'm trying to do something that this system is not meant to do.

Regards,

KC
