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"
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.
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?
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

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

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.

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.

I removed CHAP once I started running into issues. I did restart services, host, and vm.
I ended up blowing the configuration away today as I have a deadline to meet, so I'll
be continuing to use Virt-Manager for now.
I'll be using a test box of mine to work out the kinks of this and will send logs over
at that point.

When setting up the domain storage for the initial ovirt setup script, I used an ISCSI
connection to my NAS as I knew it had to be separated from the other storage domain. ISCSI
to my NAS has not been a problem.
If you have any suggestions, wonderful. If not, I'll send over logs once I can get to
my test setup and we can try to get it to work from that point. I do think Ovirt will be
worth it.
