new easy way to open issues for ovirt.org and documentation
by Greg Sheremeta 18 Feb '19

18 Feb '19

Hi, I created some footer links on ovirt.org to make it super easy to open GitHub issues. We often get questions about where to report documentation issues and things like that -- hopefully this eases the pain. When you are visiting any page on ovirt.org and you see a problem or have an idea for enhancement, simply scroll down and click 'Report an issue on GitHub'. [image: Selection_393.png] Full demo (2 minutes): https://www.youtube.com/watch?v=TbORKknLVL4 (and, of course, if you're so inclined, the Edit link starts a PR for you ...) Best wishes, Greg -- GREG SHEREMETA SENIOR SOFTWARE ENGINEER - TEAM LEAD - RHV UX Red Hat NA <https://www.redhat.com/> gshereme(a)redhat.com IRC: gshereme <https://red.ht/sig>

Huge Pages
by Vincent Royer 17 Feb '19

17 Feb '19

How do I know how many huge pages my hosts can support? cat /proc/meminfo | grep Huge AnonHugePages: 17684480 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB [image: image.png] And once I know, I set the kernel parameters here, and reboot the host, correct? [image: image.png] And then I assume I assign them to the VM here? How do I decide how many huge pages and what size a particular VM can benefit from? [image: image.png] Is there a part of the docs I am not finding that covers this?

Re: Ovirt Cluster completely unstable

Just thinking.... Maybe different options where configured to the volumes during update, that could make them unstable ? ie: sharding or something else On Sat, Feb 16, 2019, 13:26 Darryl Scott <dscott(a)umbctraining.com wrote: > Sandro > > > I don't have ovirt-log-collector on my ovirt engine.

oVirt upgrade to specific version
by Leo David 16 Feb '19

16 Feb '19

Hi, I have a running 4.2.7 hci cluster which I would upgrade to 4.2.8. If I do this in the standard manner (yum update in engine vm and then the nodes from engine UI) I assume it will go to 4.3, which I would rather avoid for now. Is there a way for getting it updated strictelly to 4.2.8 ? Thanks, Leo

Ovirt Cluster completely unstable
by dscott＠umbctraining.com 16 Feb '19

16 Feb '19

I'm abandoning my production ovirt cluster due to instability. I have a 7 host cluster running about 300 vms and have been for over a year. It has become unstable over the past three days. I have random hosts both, compute and storage disconnecting. AND many vms disconnecting and becoming unusable. 7 host are 4 compute hosts running Ovirt 4.2.8 and three glusterfs hosts running 3.12.5. I submitted a bugzilla bug and they immediately assigned it to the storage people but have not responded with any meaningful information. I have submitted several logs. I have found some discussion on problems with instability with gluster 3.12.5. I would be willing to upgrade my gluster to a more stable version if that's the culprit. I installed gluster using the ovirt gui and this is the version the ovirt gui installed. Is there an ovirt health monitor available? Where should I be looking to get a resolution the problems I'm facing.

ovirt-4.3 hyperconverged deployment - no option for "disc count" for JBOD
by feral 16 Feb '19

16 Feb '19

Vanilla install of ovirt-node-4.3 (iso). During hyperconverged wizard, there is no option for disc count for JBOD. This results in error during deployment. Disc Count option is available for all other raid levels. -- _____ Fact: 1. Ninjas are mammals. 2. Ninjas fight ALL the time. 3. The purpose of the ninja is to flip out and kill people.

Upgrade from 4.2.7 to 4.3.0 troubles
by mariani.alberto＠libero.it 15 Feb '19

15 Feb '19

Hello All, I'm trying to upgrade a Self Hosted Engine installation from 4.2.7 to 4.3.0. I was able to update the Engine itself, but when I try the general update for both the Engine VM and the Self Hosted Nodes the update fails because the openvswitch-ovn-* packages want a long series of libraries as dependencies, all with the name librte_* Unfortunately, I don't think these exist in CentOs 7, so I'm having no luck in finding them. Am I doing something wrong? Best Regards, Alberto M.
