help: Hosted-engine lost data and how to recover vm config to deploy new cluster
by Pandey, Shreyas 15 Dec '23

Hi ovirt team, There are couple of questions I am struggling to get answers for. We have ovirt cluster setup on two servers. 1) The cluster went down and upon troubleshooting we noticed the hosted engine is not able to restart. [root@j3sv7sr01ctr01 ~]# hosted-engine --vm-status The hosted engine configuration has not been retrieved from shared storage yet, please ensure that ovirt-ha-agent service is running. [root@j3sv7sr01ctr01 ~]# ovirt-ha-agent and ovirt-ha-broker both are failing because of storage related issue. The glusterfs volume which is being used by hosted-engine doesnt have the hosted engine related configuration. [root@j3sv7sr01ctr01 ~]# cd /rhev/data-center/mnt/glusterSD/ [root@j3sv7sr01ctr01 glusterSD]# ls 10.52.60.131:_j3sv7sr01datastore3 [root@j3sv7sr01ctr01 glusterSD]# cd 10.52.60.131\:_j3sv7sr01datastore3/ [root@j3sv7sr01ctr01 10.52.60.131:_j3sv7sr01datastore3]# [root@j3sv7sr01ctr01 10.52.60.131:_j3sv7sr01datastore3]# ls -al total 1 drwxr-xr-x 4 vdsm kvm 95 Dec 12 20:26 . drwxr-xr-x 3 vdsm kvm 47 Dec 13 19:16 ..

Is there anyway to recover the cluster from this state? We still have the metadata of the vms as shown below - [root@j3sv7sr01stg01 01a2b8d8-e360-41cc-beea-4080d48f436a]# pwd /mnt/datastore1/vms/6f2c0622-fa3b-48f4-b412-9bd6f20892cb/images/01a2b8d8-e360-41cc-beea-4080d48f436a [root@j3sv7sr01stg01 01a2b8d8-e360-41cc-beea-4080d48f436a]# [root@j3sv7sr01stg01 01a2b8d8-e360-41cc-beea-4080d48f436a]# [root@j3sv7sr01stg01 01a2b8d8-e360-41cc-beea-4080d48f436a]# [root@j3sv7sr01stg01 01a2b8d8-e360-41cc-beea-4080d48f436a]# [root@j3sv7sr01stg01 01a2b8d8-e360-41cc-beea-4080d48f436a]# cd ..

What other options do we have here? Any help would be really important for us. Thanks!

oVirt 4.5.0.8-1.el8 I tried to connect to grafana via the monitoring portal link from the dash and all panels are failing to display any data with varying error messages, but all include 'Origin Not Allowed' I navigated to Data Sources and ran a test on the PostgreSQL connection (localhost) which threw the same Origin Not Allowed error message. Any suggestions?

Move SHE to a LUN on another storage appliance
by Colin Coe 12 Dec '23

12 Dec '23

Hi all I'm decommissioning an old SAN that holds our DEV/TST RHV instance. I'm following https://access.redhat.com/solutions/6529691 (How to move the Hosted-Engine storage to a new storage domain) and I'm on step 9 (Make sure that the self-hosted engine is shut down). hosted-engine --vm-status is reporting: hosted-engine --vm-status | grep -E 'Engine status|Hostname' Engine status : {"vm": "up", "health": "good", "detail": "Up"} Hostname : rhvh01.example.com Engine status : {"vm": "down_unexpected", "health": "bad", "detail": "unknown", "reason": "vm not running on this host"} Hostname : rhvh02.example.com Even though the vm is definitely shut down. The instructions say call Red Hat but its nearly 6PM and we only have standard support for this environment. Any ideas on how to resolve this? I'm not sure if it's a big issue but I don't want to cause myself more problems later. Thanks

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?
