Re: [ovirt-users] Trouble Connecting ISCSI Storage to Hosted Engine

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*
