Hi,
I started an email thread a couple months ago, and felt like I got some great feedback and suggestions on how to best setup an oVirt cluster. Thanks for your responses thus far.My goal is to take a total of 3-4 servers that I can use for both the storage and the virtualization, and I want both to be highly available.
You guys told me about oVirt Hyperconverged with Gluster, and that seemed like a great option. However, I'm concerned that this may not actually be the best approach. I've spoken with multiple people at Red Hat who I have a relationship with (outside of the context of the project I'm working on here), and all of them have indicated to me that Gluster is being deprecated, and that most of the engineering focus these days is on Ceph. I was also told by a Solutions Architect who has extensive experience with RHV that the hyperconverged clusters he used to build would always give him problems.
Does oVirt support DRBD or Ceph storage? From what I can find, I think that the answer to both of those is, sadly, no.
So now I'm thinking about switching gears, and going with iSCSI instead.
But I'm still trying to think about the best way to replicate the storage, and possibly use multipathing so that it will be HA for the VMs that rely on it.
Has anyone else experienced problems with the Gluster hyperconverged solution?
Am I overthinking this whole thing, and am I being too paranoid?
Is it possible to setup some sort of software-RAID with multiple iSCSI targets?
As an aside, I now have a machine that I was planning to begin doing some testing and practicing with.
Previous to my conversations with the folks at Red Hat, I was planning on doing some initial testing and config with this server before purchasing another 2-3 servers to build the hyperconverged cluster.
