Migrate Hosted-Engine to different cluster
by Michaal R 12 Dec '23

12 Dec '23

I know this question pops up on a regular with this forum, but my best search engine manipulation turned up only to back up the engine configuration to a shared storage, then restore it on the other cluster using hosted-engine --deploy --restore-from-file=backup.tar.gz. While this is workable (it's by no means the end of the world for me), I wanted to ask if a different or better way has been or will be implemented. Here's why: I am trying to move to oVirt from ESXi (the latter has outgrown its usefulness to me and has become increasingly more difficult to maintain for my purposes, as VMware is intent on pushing newer CPU technologies with each new version, leaving perfectly good systems with perfectly good processors and hardware out in the cold. On top of that, VMware won't let you easily do vGPU or GPU passthrough without significant risk to the system stability.). I started with a VM on the ESXi host as a proof-of-concept for setting up and configuring oVirt to run the hosted engine and a couple of VMs. This worked after some great work from the members here on the forum (shout out to Tomas and Arik!). This initial cluster is an Intel CPU based cluster, as the server its VM is running on is an R720. This is the server I need to migrate off of (I have a plan). So I set up in VMware Workstation on my PC a second host in its own cluster (as that machine is an AMD CPU machine). Now, I know I can't live migr ate between clusters to begin with, but I was hoping there was an easier way to move the hosted-engine to the shared NAS storage, put the hosted-engine in maintenance mode, shut it down, change a variable or three with the --set-shared-config option (if that applies), run some script on the other host that starts the hosted-engine on that host in that cluster, bringing it out of maintenance mode automatically once up and verified stable. I understand that process COULD be slower and more fraught with danger than just simply backing up the config to shared storage and deploying on the AMD host with the restored config, but on the off-chance it ISN'T I wanted to explore that possibility. Besides, it would be a nice feature of the hosted-engine and oVirt as a whole if you could eventually right-click the hosted-engine VM in the portal and click "Move to new cluster...", which would automate that entire process for you. All that said, I'm working on one last problematic VM import before I start the arduous process of pulling everything off of ESXi and reformatting the R720 for oVirt. Hopefully that goes smoother than my start with oVirt. :)

ovirt node NonResponsive
by carlos.mendes＠mgo.cv 12 Dec '23

12 Dec '23

Hello, I have ovirt with two nodes and one that are NonResponsive and and cant manage them because they are in Unknown state. It seems that nodes lost connection for a while with their gateway. The node (ovirt2) however is having consistent problems. The follow sequence of events is reproducible and is causing the host to enter a "NonOperational" state on the cluster: What is the proper way of restoring management? I have a two-node cluster with the ovirt manager running standlone on the virtual maachine CentOS-Stream-9 and the ovirt node running the most recent oVirt Node 4.5.4 software. I can then re-activate ovirt2, which appears as green for approximately 5 minutes and then repeats all of the above issues. What can I do to troubleshoot this?

Hello oVirt folks, is there any way to install oVirt node next with sw raid (mirror) I have two disks and i would like to use them for redundancy. I know there is way to migrate from single disk to raid, https://access.redhat.com/solutions/4194011 it worked for me with RHEL8 and Centos 8 earlier, but now with Ovirt Node NG 4.5.5 it doesn't work for me. after restart, I see EFI record I can boot, but it doesn't see any raid array. thank you for any help here. jirka
