Advise needed: building cheap HA oVirt cluster with just 2 physical servers
Looking for a design advise on oVirt provisioning. I'm running a PoC lab on single bare-metal host (suddenly it was setup with just Local Storage domain) and no I'd like to rebuild the setup by making a cluster of 2 physical servers, no external storage array available. That are the options here? is there any options to build cheap HA cluster with just 2 servers? Thanks in advance! Artem

If you have no external storage and few nodes, I think your best option for storage is gluster , and the minimum number of nodes you will need for HA is 3 (the third gluster node can be metadata-only, but you still need that third node to give you quorum, avoid split-brains and have something that you can call "HA" with a straight face.

Thanks Eduardo! I think I can find a third server to build a glusterFS storage. So the first step will be to install a self-hosted engine on the new server and start building a glusterFS storage. IS there any easy way to migrate existing 5 VM's running on the second bare-metal oVirt host, right? I found a little bit tricky moving oVirt backups between the hosts (at least I failed to replicate the existing VM's on the second server).

You´ll need to build the Gluster storage first, as you´ll want to install the Hosted Engine _in_ the HA Gluster storage, right? /K

Hi, you should take a look at the hyper converged way of installing oVirt. We have a cockpit wizard that does almost everything for you: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying_Hy...

Hi, cockpit is enabled by default when you use ovirt-node. You will probably have to install the necessary cockpit packages yourself on pure CentOS - you will need cockpit and ovirt + gdeploy cockpit plugins (sadly I do not recall the exact package names). With regards to arbiter and the wizard.. I really do not know, but I will alert my colleagues who might have more detailed knowledge of the gluster part. Denis, Sahina: can you please help me here?

Hi, Can anyone share their experience on deploying hosted-engine with GlusterFS cluster? I managed to setup a GlusterFS cluster and started to deploy hosted engine. At first stage I was beaten by firewall rules - the deployment process interrupted at GlusterFS config stage. After fixing the rules I got engine up and running, but the host is non-operational state still. Logged in to Web UI -> and see 2 action points: "Gluster command failed on server" and Gluster status is disconnected for this server" This is a bit strange, since the cluster was properly detected during deployment and deployment script was supposed to configure the cluster. --== STORAGE CONFIGURATION ==-- Please specify the storage you would like to use (glusterfs, iscsi, fc, nfs3, nfs4)[nfs3]: glusterfs [ INFO ] Please note that Replica 3 support is required for the shared storage. Please specify the full shared storage connection path to use (example: host:/path): xxxx.xxxxx.xx:/oVirt [ INFO ] GlusterFS replica 3 Volume detected Do you want to configure this host and its cluster for gluster? (Yes, No) [No]: Yes [ INFO ] GlusterFS replica 3 Volume detected Any ideas how to fix this? Thanks in advance! Regards, Artem On Fri, Nov 3, 2017 at 2:28 PM, Martin Sivak <msivak@redhat.com> wrote:

cockpit is enabled by default when you use ovirt-node. You will probably have to install the necessary cockpit packages yourself on pure CentOS - you will need cockpit and ovirt + gdeploy cockpit plugins (sadly I do not recall the exact package names).
With regards to arbiter and the wizard.. I really do not know, but I will alert my colleagues who might have more detailed knowledge of the gluster part.
Denis, Sahina: can you please help me here?
Best regards
Martin Sivak
Thanks for an article, Martin! Any chance to configure a third cost to act as GlusterFS Arbitr only using this wizard?
And stupid question - how to make this wizard up and running? I've everything installed and nothing is runnin on port 9090 :)

Hi,
you should take a look at the hyper converged way of installing oVirt. We have a cockpit wizard that does almost everything for you:
hyperconverged/chap-Deploying_Hyperconverged/
It uses three hosts and collocates the VMs together with Gluster
storage.

Thanks Eduardo!
I think I can find a third server to build a glusterFS storage. So the first step will be to install a self-hosted engine on the new server and
start
building a glusterFS storage. IS there any easy way to migrate existing 5 VM's running on the second bare-metal oVirt host, right? I found a little bit tricky moving oVirt backups between the hosts (at least I failed to replicate the existing VM's on the second server).
