Recovering from corrupted hosted-engine
by timothy.dilbert＠bmt.ky 21 Jun '21

Hi Guys, We had a 2-node self-supported RHEV cluster that we used for our development environment. We're in the middle of a migration from RHEV over to VMware - one host has already been converted to VMware and we have actively been running VM migrations over to VMware. During the migration, we had an extended power outage and had to improperly shut down the RHEV host. Since bringing it back up we've not been able to start the hosted-engine. Each time we try to start the hosted engine we're getting the following messages: ## START [root@bmrhev01 ~]# hosted-engine --vm-start VM exists and is down, cleaning up and restarting VM in WaitForLaunch [root@bmrhev01 ~]# hosted-engine --vm-status --== Host bmrhev01 (id: 1) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : bmrhev01 Host ID : 1 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down_unexpected", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 325ff4b3 local_conf_timestamp : 7920 Host timestamp : 7920 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=7920 (Tue Jun 15 14:59:32 2021) host-id=1 score=3400 vm_conf_refresh_time=7920 (Tue Jun 15 14:59:32 2021) conf_on_shared_storage=True maintenance=False state=EngineStarting stopped=False END ## We've tried rebooting a number of times. Restarting various oVirt services. Nothing appears to be resolving the issue. At this point, the only thing I truly care about is migrating the guest VMs over to VMware. There's nothing else in the RHEV environment I care about. I'm happy to settle with any of the following, providing they can salvage the guest VMs: a) Deleting and redeploying the hosted-engine. b) Abandoning the hosted-engine and some how converting the guest VMs over to VMware. I don't have enough experience to know if any of the above is possible or the repercussions of either of them. Any help from anyone would be very helpful. I'm sorry to be a leach, rather than a contributor. I'm seriously in trouble here and a kind heart would be much appreciated. Thanks, Tim.

oVirt + Gluster issues
by suporte＠logicworks.pt 21 Jun '21

21 Jun '21

Hello, running ovirt 4.4.4.7-1.el8 and gluster 8.3. When i performe a restore of Zimbra Collaboration Email with features.shard on, the VM pauses with an unknown storage error. When I performe a restore of Zimbra Collaboration Email with features.shard off, it fills all the gluster storage domain disks. With older versions of gluster and ovirt the same happens. If I use a NFS storage domain it runs OK. -- Jose Ferradeira http://www.logicworks.pt

/var/log has less then 500MB free space left on
by Andrei Verovski 21 Jun '21

21 Jun '21

Hi, I started to get messages that /var/log has less then 500MB free space left on out of 8GB. du -h —max-depthh=1 reveals that openswitch log dir consumes 3.6GB, there are files as old as 2018. Node software was installed on fresh CentOS 7.xx from oVirt admin web console. I cleaned this directory, yet question remain - why logrotate service is not running by default on oVirt node? Or this is not recommended? Thanks in advance. Andrei

Customization of Ovirt VM Portal
by Alessio B. 17 Jun '21

17 Jun '21

Hello to all, please is there a way to customize the VM portal? In my case I need to hide the "VNC console" value from the dropdown list inside of selected VM properties and leave only "VNC Console Browser". The user profile is "UserRole" Thank you very much!

RFC8482 and engine-setup
by Strahil Nikolov 14 Jun '21

14 Jun '21

Hello All, recently I have changed my firewall and DNS server and I have noticed that engine-setup warns with: Failed to resolve engine.localdomain using DNS, it can be resolved only locally. The command used was: 'dig +noall +answer FQDN ANY' It seems that according to RFC8482, ANY is deprecated and DNS can return anything.Once such example is the output of 'dig wikipedia.org ANY' . What are our options now ? I guess we can query for A and AAAA records ? Extra info: https://blog.cloudflare.com/rfc8482-saying-goodbye-to-any/ Best Regards,Strahil Nikolov
