Can you set one of the Hypervisours into maintenance and use the "reinstall" option from the UI ?

Re: Migration of self Hosted Engine from iSCSI to Gluster/NFS
by Strahil Nikolov 28 Jun '20

As you will migrate from block-based storage to file-based storage, I think that you should use the backup & restore procedure.

engine failure
by eevans＠digitaldatatechs.com 28 Jun '20

28 Jun '20

The last update for 4.3 has caused my engine server to fail. I cannot find the original repos for the 4.3 install that work with out missing dependencies. I am using Centos 7 that is up to date. Can someone forward the URL for 4.3.10.1 repo installs or info so I can reinstall and hopefully restore my stand alone engine? My vm's are still running but I cannot manage anything . Please help and it is appreciated.

Does a slow Web proxy (can't run the update-check) ruin HA scores? (Solved, ...but really?)
by thomas＠hoberg.net 27 Jun '20

27 Jun '20

Running a couple of oVirt clusters on left-over hardware in an R&D niche of the data center. Lots of switches/proxies still at 100Mbit and just checking for updates via 'yum update' can take awhile, even time out 2 times of out 3. The network between the nodes is 10Gbit though, faster than any other part of the hardware, including some SSDs and RAIDs: Cluster communication should be excellent, even if everything goes through a single port. After moving some servers to a new IP range, where there are even more hops to the proxy, I am shocked to see the three HCI nodes in one cluster almost permanently report bad HA scores, which of course becomes a real issue, when it hits all three. The entire cluster really starts to 'wobble'.... Trying to find the reason for that bad score and there is nothing obvious: Machines have been running just fine, very light loads, no downtimes, reboots etc. But looking at the events recorded on hosts, something like "Failed to check for available updates on host <name> with message 'Failed to run check-update of host '<host>'. Error: null'." does come up pretty often. Moreover, when I then have all three servers run the update check on the GUI, I can find myself locked-out of the oVirt GUI and once I get back in, all non-active HostedEngine hosts are suddenly back in the 'low HS score' state. So I have this inkling impression, that the ability (or not) to run the update check is counting into the HA score, which ... IMHO would be quite mad. It would have production clusters go haywire, just because an external internet connection is interrupted... Any feedback on this? P.S. Only minutes later, after noticing the ha-scores reported by hosted-engine --vm-status were really in the low 2000s range overall, I did a quick Google and found this: ovirt-ha-agent - host score penaltieshttps://github.com/oVirt/ovirt-hosted-engine-ha/blob/master/ovirt_… NOTE: These values must be the same for all hosts in the HA cluster!base-score=3400 gateway-score-penalty=1600 not-uptodate-config-penalty=1000 //not 'knowing if there are updates' is not the same as 'knowing it missing critical patches' mgmt-bridge-score-penalty=600 free-memory-score-penalty=400 cpu-load-score-penalty=1000 engine-retry-score-penalty=50 cpu-load-penalty-min=0.4 cpu-load-penalty-max=0.9 So now I know how to fix it for me, but I'd consider this pretty much a bug: When the update check fails, that implies really only that the update check could not go through. It doesn't mean the cluster is fundamentally unhealthy. Now I understand how that negative feedback is next to impossible inside RedHat's network, where update servers are local. But having a cluster HA score being based on something 'just now happening' on the other far edges of the Internet... seems a very bad design decision. Please comment and/or tell me how and where I should file this as a bug.

NFS import storage domain permissions error
by Joop 27 Jun '20

27 Jun '20

Hi All, I've got an error when I try to import a storage domain from a Synology NAS that used to be a 4.3.10 oVirt installation but no matter what I try I can't get it to import. I keep getting a permission denied error while with the same settings it worked for the previous version oVirt.

Had a look at the source of vdsm/storage/* but I'm not a python programmer. A couple of other 4.4 oVirt installs don't have this problem and I used the same usb stick with Centos-8.2 for those as for this one. Followed the same install instructions, same versions of packages as far as I can see. Beats me I'm tempted to reinstall Centos7 and oVirt4.3.10 just to see what happens, but I'm hoping someone can point me to something that I must have overlooked. Regards, Joop

How to suspend a stateless VM
by pascal＠butterflyit.com 26 Jun '20

26 Jun '20

Currently from the ovirt web interface it is not possible to suspend a stateless VM. However I have a need for it for example when I want to free idle VM (or migrate them to a different cluster) and still not lose the current status of the VM. Thanks

How to change the hosted engine configuration manually?
by Ricardo Alonso 26 Jun '20

26 Jun '20

After an update in the cluster configuration, the hosted engine ended up with an invalid configuration (bios x machine type) and it's not coming up. I need to return the bios to legacy mode, but I'm not finding a way to correct the xml generated to turn the machine back on. The storage domain is iSCSI. Any help would be appreciate. (reinstall isn't an option).
