[ovirt-users] Re: Major problems after upgrading 2 (of 4) Red Hat hosts to 4.4.10
Thank you very much. Over the course of troubleshooting, I did wind up updating (and rebooting) the engine. The issue "magically" resolved itself a few hours after I sent this email with the two Gluster nodes. They became operational again, and thus, I wound up having enough compute power to bring everything back online. That said, the compute-only node is still not operational. I'll take a look at the "gluster pool list" command. Thank you for that.

Check the situation with the gluster storage.Also, you can check if the compute-only node is added to the gluster trsuted storage pool:gluster pool list (should show localhost -+ 2 more). Also, consider upgrading the engine. Most probably the engine cannot connect to the vdsm and vdsm-gluster and this makes the whole situation worse.

[ovirt-users] New oVirt setup with OVN : Hypervisor with LACP bond : queries
Hello team, Thank you for all the wonderful work you've been doing. I'm starting out new with oVirt and OVN. So please excuse me if the questions are too naive. We intend to do a POC to check if we can migrate VMs off our current VMware to oVirt. The intention is to migrate the VMs with the same IP into oVirt. We've setup oVirt with three hypervisors. All of them have four ethernet adapters. We have SDN implemented in our network and LACP bonds are created at the switch level. So we've created two bonds, bond0 and bond1 in each hypervisor. bond0 has the logical networks with vlan tagging created like bond0.101, bond0.102 etc. As a part of the POC we also want to explore OVN as well to check if we can implement a zero trust security policy. Here are the questions now :) 1. We would like to migrate VMs with the current IP into oVirt. Is it possible to achieve this? I've been reading notes and pages that mention about extending the physical network into OVN. But it's a bit confusing on how to implement it. How do we connect OVN to the physical network? Does the fact that we have a SDN make it easier to get this done? I am still reading the ovn-architecture page. It is mentioned that the gateway is the component that extends a tunnel-based logical network into a physical network. 2. We have the IP for the hypervisor assigned on a logical network(ovirtmgmt) in bond0. I read in https://lists.ovirt.org/archives/list/users@ovirt.org/thread/CIE6MZ47GRCEX4Z6GWRLFSERCEODADJY/ that oVirt does not care about how the IP is configured when creating the tunnels. 3. Once we have OVN setup, ovn logical networks created and VMs created/migrated, how do we establish the zero trust policy? From what I've read there are ACLs and security groups. Any pointers on where to explore more about implementing it. If you've read till here, thank you for your patience.

[ovirt-users] Major problems after upgrading 2 (of 4) Red Hat hosts to 4.4.10
I have a Hyperconverged cluster with 4 hosts. Gluster is replicated across 2 hosts, and a 3rd host is an arbiter node. The 4th host is compute only. I updated the compute-only node, as well as the arbiter node, early this morning. I didn't touch either of the actual storage nodes.That said, I forgot to upgrade the engine. oVirt Manager thinks that all but 1 of the hosts in the cluster are unhealthy. However, all 4 hosts are online. oVirt Manager (Engine) also keeps deactivating at least 1, if not 2 of the 3 (total) bricks behind each volume. Even though the Engine thinks that only 1 host is healthy, VMs are clearly running on some of the other hosts. However, in troubleshooting, some of the customer VMs were turned off, and oVirt is refusing to start those VMs, because it only recognizes that 1 of the hosts is healthy -- and that host's resources are maxed out. This afternoon, I went ahead and upgraded (and rebooted) the Engine VM, so it is now up-to-date. Unfortunately, that didn't resolve the issue. So I took one of the "unhealthy" hosts which didn't have any VMs on it (which was the host that is our compute-only server hosting no gluster data), and I used oVirt to "reinstall" the oVirt software. That didn't resolve the issue for that host. How can I troubleshoot this? I need: - To figure out why oVirt keeps trying to deactivate volumes - From the command line, `gluster peer status` show all nodes connected, and all volumes appear to be healthy - More importantly, I need to get these VMs that are currently down back online. Is there a way to somehow force oVirt to launch the VMs on the "unhealthy" nodes? What logs should I be looking at? Any help would be greatly appreciated .

[ovirt-users] Re: mdadm vs. JBOD
Using the wizzard is utilizing the Gluster Andible roles.I would highly recommend using it, unless you know what you are doing (for example storage alignment when using Hardware raid). Keep in mind that the DHT xlator (the logic in distributed volumes) is shard aware, so your shards are spread between subvolumes and additional performance can be gained.So using replicated-distributed volumes have their benefits. If you decide to avoid the software raid, use only replica3 volumes as with SSDs/NVMEs usually the failures are not physical, but logical (maximum writes reached -> predictive failure -> total failure). Also, consider mounting via noatime/relatime and context="system_u:object_r:glusterd_brick_t:s0" for your gluster bricks.
