So it looks like I'm going to move to a new datacenter. I went into somewhere cheap on a month-to-month contract earlier this year, and they've been a pain to deal with. At the same time, I've grown a lot faster than expected, so I've decided to move into a better, more reputable datacenter sooner rather than later.
I currently have HCI with 3 servers. Within the cluster, I can tolerate a host "failure", so I can run on 2 servers. I have a 4th server that I haven't really been doing anything yet, but I think will be a good asset to me as I move, to keep things to a minimum. One of my production nodes, as well as my 4th server don't have the right storage, so if/when I move things, I'll need to configure Gluster to run on a single node for a time.
I'd like to ask about best practices here.
Before I move any hardware, I'm thinking about removing 1 of my 3 production servers from the existing HCI cluster, and installing a NEW hyperconverged single node onto this production server with Gluster storage. Then, add my 4th server to that new oVirt environment. Once I did that, I'm wondering if I could clone 100% of the VMs from the 1 environment over to the other.
Once that was done, I could move one of my oVirt clusters to the new datacenter, update DNS for the virtual servers, run a final rsync, and I'm done -- then I would just move the other two servers, do a fresh install of oVirt, and add them to the new cluster.
Is this possible?
Is there a better way to do this move?
Thanks,
David
