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:
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?
Best regards

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.
Best regards

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).

For HA you will need some kind of storage available to all the

nodes in the cluster. 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

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.

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!
