Re: HostedEngine VM Paused after power failure

Robert, I understand the sentiment of the difficulty here. The recovery feels brutal but the monolithic nature and the dense ecosystem is understandable for the purpose it serves. I am able to mount the raw disk image for the HostedEngine VM cleanly without any errors and it seems to check out, so I don't believe there is any corruption. Everything looks to operate as expected and then it just seems to snag somewhere through the startup. I suppose I'm just trying to trace down the hiccup to clear it out of the way and let the VM boot up. My knowledge is a bit limited digging in and troubleshooting the components here. Additional snippet: MainThread::INFO::2021-02-09 21:00:07,357::hosted_engine::863::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(_start_engine_vm) stderr: Command VM.getStats with args {'vmID': '74b3c839-c89c-4857-ada0-95715672348a'} failed: (code=1, message=Virtual machine does not exist: {'vmId': '74b3c839-c89c-4857-ada0-95715672348a'}) MainThread::INFO::2021-02-09 21:00:07,357::hosted_engine::875::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(_start_engine_vm) Engine VM started on localhost MainThread::INFO::2021-02-09 21:00:07,389::brokerlink::73::ovirt_hosted_engine_ha.lib.brokerlink.BrokerLink::(notify) Success, was notification of state_transition (EngineStart-EngineStarting) sent? ignored MainThread::INFO::2021-02-09 21:00:07,406::hosted_engine::517::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(_monitoring_loop) Current state EngineStarting (score: 3400) MainThread::INFO::2021-02-09 21:00:17,427::states::740::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(consume) Another host already took over.. *Thank you,* *Ian Easter* On Tue, Feb 9, 2021 at 6:31 PM Robert Tongue <phunyguy(a)neverserio.us> wrote: > I've seen this happen with the VM disk itself becoming corrupt.

Single Node Hyperconverged - Failing Gluster Setup
by jhamiltonactually＠gmail.com 10 Feb '21

10 Feb '21

Ovirt newbie here - using v 4.4.4 Have been trying for days to get this installed on my HP DL380p G6. I have 2 disk 170GB Raid 0 for OS and 6 x 330GB disk Raid 5 for Gluster. DNS all set up (that took some working out), but I just can't fathom out whats (not) happening here. Block size is returned as 512. I've had some help on Reddit where I've been told that Ovirt is seeing my single local disk ass an multipath device, which it is not/??! I think I removed the flag, but it still fails here. So, Gluster install fails quite early through, though it carries on creating all the volumes (with default settings) but then gives me the 'Deployment Failed' message :( Here is where it fails.... Any help gratefully received!

HostedEngine VM Paused after power failure
by Ian Easter 10 Feb '21

10 Feb '21

Hello Users, We have an oVirt (4.4) environment that had 2 hosts in the cluster. We suffered from a power failure that caused the servers to be offline for some time. Once restored, one of the hosts from the cluster lost its OS raid and is not accessible. The other server has the HostedEngine vm on it but in a paused state. I have tried to manually start the vm with the hosted-engine CLI tool but it indicates that HostedEngine is running on another host. Is there any manual intervention I can accomplish here to start the HostedEngine on the second, active host server? *Thank you,* *Ian Easter* *DevOps Engineer* *TelVue Support* https://www.telvue.com/support/

Random Crash
by francesco＠shellrent.com 09 Feb '21

09 Feb '21

Hi all, I'm experiencing random reboot on several oVirt nodes (CentOS 7/8, oVirt 4.3/4.4 as well). Sometimes it happens three times in a day, and the more hosts I'm adding to my pool, the more I noticing. The logs are not helpful: it's like a brute poweroff cause there are no entries at all in the messages, vdsm, secure (I looked all over the logs) from the last "normal" entry (user logged in/off, normal vdsm log ecc.) until the first entry of the boot. kdump is enabled and /var/crash is empty. I used to run Xen on the servers of the same provider and I didn't have all of these frequent reboots, that's why I'm not sure it is a hardware related issue. Any advice on what enables for getting more info about this crash? Thank you for your time, Francesco

Hi oVirt Users, I am trying to test some vfio related stuff on oVirt Node NG 4.4.4 based host. What would be the easiest way to have a 5.x kernel on this node? I don't mind compiling if it needs to. Cheers, Shantur

The he_fqdn proposed for the engine VM resolves on this host - error?
by lejeczek 07 Feb '21

07 Feb '21

hi chaps, a newcomer here. I use cockpit to deploy hosted engine and I get this error/warning message: "The he_fqdn proposed for the engine VM resolves on this host" I should mention that if I remove the IP to which FQDN resolves off that iface(plain eth no vlans) then I get this: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The selected network interface is not valid"} All these errors seem bit too cryptic to me. Could you shed bit light on what is oVirt saying exactly and why it's not happy that way? many thanks, L.

Future of oVirt as RHV is converging with OpenShift
by andrew.prowse＠gmail.com 06 Feb '21

06 Feb '21

What is the future of oVirt with RHV 4.4 being the last RHV release? - see https://access.redhat.com/support/policy/updates/rhev With the release of RHV 4.4 Red Hat continues to invest in and support customers with a production-ready virtualization portfolio. The latest addition to this portfolio is OpenShift with OpenShift Virtualization, which provides continuity and roadmap delivery for the KVM-based virtualization stack currently managed by RHV. Moving forward the RHV management feature set will be converged with OpenShift and OpenShift Virtualization providing customers with requirements for containers and VMs a migration path and a common platform for deploying and managing both.
