VDSM ConnectStorageServerVDS failed
by JC Clark 25 Jun '17

Dear All, Is there a reason that a perfectly well working Ovirt 4.1 Engine after a power failure, would not allow the hosts to activate because of "VDSM ConnectStorageServerVDS failed". All firewalls are down, I have reinstalled the host, upgraded everything (host and engine), deleted and reinstalled hosts, I can ssh to all from all. Any clues?? Thanks ahead of time.. -- Warm Regards, JC Clark IT Director Mount Carmel School Saipan, CNMI

by Matt . 24 Jun '17

Hi guys, When you want to move your hosted_engine storage you can copy stuff over but you still need to change the image which contains all config files. Is there some documentation about how to do so ? Thanks, Matt

Info on live snapshot and agent interaction
by Gianluca Cecchi 23 Jun '17

23 Jun '17

Hello, supposing to have a Linux VM with ovirt-guest-agent installed, during a live snapshot operation it should be freeze of filesystems. Where to find confirmation of correct/successful interaction? /var/log/messages or agent log or other kind of files? Are there any limitations on filesystems that support freeze? Is it fsfreeze the command executed at VM OS level or any other low level command? Thanks, Gianluca

Frustration defines the deployment of Hosted Engine
by Vinícius Ferrão 23 Jun '17

23 Jun '17

Hello oVirt folks. I’m a traitor of the Xen movement and was looking for some good alternatives for XenServer hypervisors. I was aware of KVM for a long time but I was missing a more professional and appliance feeling of the product, and oVirt appears to deliver exactly what I’m looking for. Don’t get me wrong, I’m not saying that Xen is not good, I’m looking for equal or better alternatives, but I’m starting to get frustrated with oVirt. Firstly I’ve tried to install the oVirt Node on a VM in VMware Fusion on my notebook, it was a no go. For whatever reasons I don’t know vdsmd.service and libvirtd failed to start. I make sure that I was running with EPT support enabled to achieve nested virtualization, but as I said: it was a no go. So I’ve decommissioned a XenServer machine that was in production just to try oVirt. The hardware is not new, but’s it’s very capable: Dual Xeon E5506 with 48GB of system RAM, but I can’t get the hosted engine to work, it always insults my hardware: --- Hosted Engine deployment failed: this system is not reliable, please check the issue,fix and redeploy. It’s definitely a problem on the storage subsystem, the error is just random, at this moment I’ve got: [ ERROR ] Failed to execute stage 'Misc configuration': [-32605] No response for JSON-RPC StorageDomain.detach request. But on other tries it came up with something like this: No response for JSON-RPC Volume.getSize request. I was thinking that the problem was on the NFSv3 server on our FreeNAS box, so I’ve changed to an iSCSI backend, but the problem continues. This happens at the very end of the ovirt-hosted-engine-setup command, which leads me to believe that’s an oVirt issue. The OVA was already copied and deployed to the storage: [ INFO ] Starting vdsmd [ INFO ] Creating Volume Group [ INFO ] Creating Storage Domain [ INFO ] Creating Storage Pool [ INFO ] Connecting Storage Pool [ INFO ] Verifying sanlock lockspace initialization [ INFO ] Creating Image for 'hosted-engine.lockspace' ...

And the log file is too verborragic (hoping this word exists) to look for errors. Any guidance? Thanks, V.

Hello I'm trying to update the BIOS firmware on a Dell PowerEdge with CentOS (just upgraded to 7.3) running oVirt 4.0 and it fails with an error mount: /dev/sdb is already mounted or /tmp/SECUPD busy The problem is acknoleged by Red Hat and there is a solution for it https://access.redhat.com/solutions/2671581 but well, I have no RH subscriptions :( Has anyone here encountered the same problem with CentOS and oVirt? Any hint? Thanks! -- Davide

is arbiter configuration needed?
by Erekle Magradze 23 Jun '17

23 Jun '17

Hello, I am using glusterfs as the storage backend for the VM images, volumes for oVirt consist of three bricks, is it still necessary to configure the arbiter to be on the safe side? or since the number of bricks is odd it will be done out of the box? Thanks in advance Cheers Erekle
