host NonResponsive after trying to update network MTUs
by Edward Berger 31 Jan '19

31 Jan '19

I have a problem host which also is the one I deployed a hyperconverged oVirt node-ng cluster from with the cockpit's hyperconverged installation wizard. When I realized after deploying that I hadn't set the MTUs correctly for the engine-mgmt, associated vlan and eno.2 device and also for my infiniband interface ib0, I went in and tried to set them to new values 9000 and 65520 it got into some kind of hung state. The engine task window shows a task in "executing" and a never ending spinning widget "Handing non responsive Host track00..." I can tried updating the hosts /etc/sysconfig/network-scripts by hand. I've tried every combination of the engines set host in maintenance mode , "sync networks" "refresh host capabilities" activating and rebooting, but I'm still stuck with an unresponsive host. I had another host that also failed but it allowed me to put it into maintenance mode and then remove it from the cluster and "add new" it back and it was happy. This one won't let me remove it because its serving the gluster volume mount point, even though I did give the mount options for the 2nd and 3rd backup volume servers. I'd appreciate any help restoring it to proper working order. I'm attaching the gzip'd engine log.

31 Jan '19

Hello everyone, I have the following script, i ve been looking in ovirt-sdk but i cannot seem to find the proper way of adding an external provider network under ovirt-ovn I manage to add logical networks and vlans but no luck in external provider. Any advice is appreciated network = networks_service.add( network=types.Network( name='ext_net', description='Testing network', data_center=types.DataCenter( name='Default' ), usages=[types.NetworkUsage.VM], external_provider='ovirt-provider-ovn', -->i know this part is wrong what is it supposed to be called? ),

Changing CPU type in oVirt Cluster 4.2
by Juhani Rautiainen 31 Jan '19

31 Jan '19

Hi! I made two node oVirt cluster with self hosted engine. It's running top of oVirt Node 4.2. Hardware is built on AMD Epyc processors. I just noticed that "Clusters"-view warns that I have AMD Opteron G3 as CPU type and it will not supported in the future. Didn't check this during installation so it probably came automatically. But question is how can I change this? I get warning 'Error while executing action: Cannot change Cluster CPU to higher CPU type when there are active Hosts with lower CPU type.'. I saw old thread from 2016 where it was suggested that you change value straight to db. Put that seems bit dangerous. Is there any other way to solve this problem? Thanks, Juhani -- Juhani Rautiainen jrauti(a)iki.fi

VDO volume - storage domain size
by Leo David 31 Jan '19

31 Jan '19

Hello Everyone, I'm I trying to benefit of vdo capabilities, but it seems that I don;t have too much luck with this. I have both created a vdo based gluster volume usign both following methods: - at hyperconverged wizard cluster setup by enabling compression per device - after installation, by creating a new gluster volume and enabling compression In both cases, I end up with a real device size gluster volume/storage domain, although the vdo's appear in node's cockpit UI as being 10 times then physical device. ie: 3 nodes, each having 1 x 900GB ssd device, turns into 9t device vdo device per host, but the storage domain (gluster replica 3 ) ends up as being 900GB . Am I missing something , or maybe doing something wrong? Thank you very much ! Leo Best regards, Leo David

Roles and Permissions and Inheritance
by Brian Wilson 30 Jan '19

30 Jan '19

Is there a way to prevent Roles Assigned to Groups on Objects to only apply to where it is set? Basically looking for a way to do what we had done in VMWare which involved using the do not propagate permission setting. be able Seems to me that right now there is no way to set this so if i give access to something at the top level of a DC those accesses wlll overide if i then explcitly set another role and permission on an object underneath Lets take as a concrete example the ovirtmgmt network. I do not want users in the engine to be able to place VMs on this (but i want the Superusers to be able to still) How can i accomplish this with the way roles and permissions work with Ovirt? thanks! Brian

Ovirt configuration
by matteofedeli97＠gmail.com 30 Jan '19

30 Jan '19

Hi at all, I'm installing and configuring a ovirt system in hyperconverged mode and I have some doubt about storage. server 1: 1TB, 1TB server 2: 1TB, 1TB server 3: 1TB, 1TB With this hdd configuration I want on the first drive install ovirt node, vmstore and engine volume, on the second another volume for data. The first in Replica 3 and the second distribuited... It's possible? During installation of ovirt node in the automatic partitioning should I select both hard disk? In the cockpit wizard in this step, https://www.ovirt.org/images/uarwo42-gdeploy-3.png?1519899774, to recover the device name i use pvdisplay -m?
