<div>Hello oVirt Community,</div>
<div> </div>
<div>This may be my first time writing in. Although, I’ve been reviewing and playing with oVirt for the past 3 years. My name is Robert Langley and I work for a local Government in Southern California. My agency (with me as the primary/lead IT person) has been
using VMWare vSphere to host our server environment for 6 years. I have a few different reasons I want to jump the VMWare ship and I’ve been pleased with the progression oVirt has been making. I do not care to jump from VMWare to Microsoft’s Hyper-V, so this
had lead me to look into Xen for a while, then dropped anchor with oVirt. I’m determined to see this implementation through.</div>
<div> </div>
<div>I have moved over from the test (workstation class) environment, where I was really just getting familiar with the commands and UI, and now I am working on implementation with server class hardware.</div>
<div>I have the engine up and running. I’ll get into more specifics below.</div>
<div>I’m running into an issue where I have not been able to add my Gluster hosts or add the Storage Domain (I had tried adding the storage domain first).</div>
<div>For my new oVirt and GlusterFS hosts I have the following:</div>
<ul style="margin:0;padding-left:36pt;">
<li>I want to first mention that I do have a DNS server for the separated/private networks and those are configured and working properly (forward & reverse).</li></ul>
<div>Dell PE R830 and I would like this to be a failover server housed in a separate building where we have an Emergency Operations Center and Datacenter (server room).</div>
<ul style="margin:0;padding-left:43pt;">
<li>Has bonded gigabit (2 port) network that is connected to our main network & internet, configured to be used for ovirtmgnt. Name = gsaov08.ent…</li></ul>
<ul style="margin:0;padding-left:79pt;">
<li>As far as all the various names, oVirt Hosted Engine Deployment complained that the Main network name was seen on more than one interface, or something to that effect.</li><li>I did originally have DNS for the separated/private networks configured for forwarding DNS from our main network DNS servers. Which has been removed and the Hosted Engine Deployment stopped complaining at that point. I was going to use the forwarding DNS
for another private network I use for some management traffic, but that is not as important or an absolute need either.</li></ul>
<ul style="margin:0;padding-left:43pt;">
<li>Has 2<font size="1"><span style="font-size:7.3pt;"><sup>nd</sup></span></font> bonded gigabit (4 port) network (separate/private) for engine storage. Name = gsaov08e.engine.local</li><li>Has 3<font size="1"><span style="font-size:7.3pt;"><sup>rd</sup></span></font> bonded 10G (2 port) network (separate/private) for VM Guest storage. Name = gsaov08s.stor.local</li><li>Will have a 4<font size="1"><span style="font-size:7.3pt;"><sup>th</sup></span></font> network (separate/private) configured for security related devices that are managed by a couple of our VM guests.</li></ul>
<div style="padding-left:25pt;">As far as storage in this same server.</div>
<ul style="margin:0;padding-left:43pt;">
<li>I have split up the local storage to be hosted by GlusterFS and this host is a peer with the other two dedicated GlusterFS storage servers. That is for the failover piece.</li></ul>
<ul style="margin:0;padding-left:79pt;">
<li>Engine volume (currently being used for the Hosted Engine) and setup as a replica 3 with the two dedicated GlusterFS storage servers.</li><li>VM Guest “Data” volume. The volume is created, configured and started. Setup as a replica 3 with the two dedicated GlusterFS storage servers.</li></ul>
<div style="text-indent:36pt;">So far, this is the only host I have hosting the engine. Now, onto the other host I am about to run Hosted-Engine -Deploy on.</div>
<div>Dell PE R730 – It has the same network setup as the R830. Storage is a bit different. I would like to run another VM Guest GlusterFS volume from here, along with 2 other hosts I have. They are currently serving as the vSphere ESX hosts and have the same
total size of storage to create another replica 3.</div>
<div> </div>
<div>The Dedicated GlusterFS Hosts are custom AMD Opteron G2 builds with ASUS server motherboards. Strictly designed to be dedicated storage servers.</div>
<ul style="margin:0;padding-left:43pt;">
<li>I’m using the onboard NICs to connect to my management network only for the purpose of getting updates. So, internet is served to these hosts via a NAT router. Since I figured they don’t otherwise need access to our main network. The primary names = gsa-stor1
& gsa-stor2</li><li>They both have a bonded (4 port) gigabit network for the Engine storage network. Names = gsa-stor1e.engine.local & gsa-stor2e.engine.local</li><li>They both have a bonded (2 port) 10G network for the VM Guest storage network. Names = gsa-stor2s.stor.local & gsa-stor2s.stor.local</li></ul>
<div style="padding-left:25pt;">As far as storage in these servers.</div>
<ul style="margin:0;padding-left:43pt;">
<li>It is the same as the R830, as these servers are the peers to the R830.</li></ul>
<div style="padding-left:43pt;"> </div>
<div>First, I added an ISO Storage Domain (NFS). That was successful. Next, I was trying to add the GlusterFS VM Guest Data Storage Domain. I receive an Operation Canceled: Error while executing action AddGlusterFsStorageDomain: Error creating a storage domain.</div>
<div>When I try to add the Gluster hosts as hosts in the oVirt Manager, I get a message stating that SSH has failed, verify that the host is reachable (IP address, routable address etc.) You may refer to the engine.log file for further details.</div>
<div>I can otherwise communicate with the hosts and the engine.log does not appear to have specifics to this particular failure. But, there are other clues that I don’t understand. So, I can follow up with the engine log. It contains “WARN” entries. They seem
to be because I do not have the hosts, for the engine volume, added to the cluster.</div>
<div>Oh, one thing I should mention, I did select the option to enable the Gluster service in the default cluster. So, both virt and Gluster are enabled. After I did so, I wasn’t so sure that was a good thing or not. It seems that documentation is outdated
on whether that is now supported. I noticed from screenshots that the selection used to be radio buttons and now they are check boxes. I did read the release notes for 4.0.1, which seem to talk as though support for both in a cluster has been added.</div>
<div> </div>
<div>Thank you for any help that can be extended.</div>
