[ovirt-users] Re: Q: Hybrid GlusterFS / local storage setup?

Hi Gilboa, I think that storage domains need to be accessible from all nodes in the cluster - and as yours will be using local storage and yet be in a 2-node cluster that will be hard. My guess is that you can try the following cheat:  Create a single brick gluster volume and do some

Hi, I would start with  https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_using_the_cockpit_web_interface/ . It might have some issues as 4.4 is quite fresh and dynamic, but you just need to ping the community for help over the e-mail. Best Regards, Strahil Nikolov

[ovirt-users] Re: How to make oVirt + GlusterFS bulletproof

strict-o-direct just allows the app to define if direct I/O is needed and yes, that could be a reason for your data loss. The good thing is that the feature is part of the virt group and there is a "Optimize for Virt" button somewhere in the UI . Yet, I prefer the manual approach of building

[ovirt-users] Re: oVirt SHE smart-automated backup

I don't see any reasons to be worried about. Yet, you can create your own Cluster scheduling policy and ensure one node is always available as a stand-by which you can just put into maintenance during backups , or to hold your VMs when other hosts are in maintenance. Best Regards, Strahil

Hi David, i admit that I have some cases with Gluster Hyperconverged, but having in mind that I'm always on the bleeding edge (I'm a little bit behind on my oVirt now) with 1 Gluster version ahead of the default for oVirt -> I think it's acceptable. It doesn't matter which storage

I guess you can experiment a little bit. Have you tried to 'inject' a task before the failing one to add the options you need via 'blockinfile' or 'lineinfile'. I think the simplest way is to add a 'pause' task , that will give you enough time to: - Find the IP of the local engine vm - ssh to

[ovirt-users] Re: Gluster Volume Type Distributed

Yes it is. You can still install and setup Gluster all by yourself (lots of manual steps) and then use that as a storage. Yet, replica 1 and replica 3 (or replica 3 arbiter 1) are the only supported in Ovirt. Best Regards, Strahil Nikolov  В четвъртък, 27 август 2020 г., 18:28:55

Actually ISO domain is not necessary. You can moutn it via FUSE to a system and either use the python script ( It was mentioned several times in the mailing list) or the API/UI to upload your ISOs to a data storage domain. I think it is about time to get rid of the deprecated ISO domain. Best
