Ok.  The oVirt Node installation sets up partitions to use the entire disk.  (Documentation recommends using the default layout.)  The Cockpit HE deployment tries to use gluster, but on a different disk (non-existent).  Do you recommend that I not use the default partitioning when installing oVirt Node; instead, I should set aside a partition for gluster (not formatting, etc)?

Thanks,
Mike

Mike,

Keep it simple. It has to be a bare, plain disk.
Do not format or put a file system on the disk or the gluster install will fail.

I installed oVirt node for oVirt v4.3.4 on a single server (default
partitioning).  I know a single node is not best practice, but fits our
current need.

Now, I am trying to deploy the hosted engine, but getting the error
"Device /dev/sdb not found" (full output below).  /dev/sdb does not
exist.  Changing to /dev/sda fails (as I would expect) with "Creating
physical volume '/dev/sda' failed".  There is only one logical disk on
this server (RAID), which is /dev/sda.

The process does not seem correct to me.  Why would the wizard try to
build gluster volumes on bare partitions rather than in a file system
like root?  What do we need to do to deploy the HE?

I used Cockpit and "Hyperconverged : Configure Gluster storage and oVirt
hosted engine".  Since it is a single node, I selected "Run Gluster
Wizard For Single Node".
