Re: Arbiter brick disk performance
by Strahil 28 Apr '19

28 Apr '19

I think 2 small ssds (raid 1 mdadm) can do the job better as ssds have lower latencies .You can use them both for OS (minimum needed is 60 GB) and the rest will be plenty for an arbiter. By the way, if you plan using gluster snapshots - use thin LVM for the brick.

NVME-oF
by Daniel Menzel 26 Apr '19

26 Apr '19

Hi guys, just out of curiosity: Have there been any attempts yet to use NVMe over Fabrics as Storage-Backend in oVirt? We have used NVMe-oF several times in the past few weeks/month and its an absolutely gorgeous technology - and more than perfect for virtualization.

Re: Ovirt 4.3.2 VM Failover
by Strahil 26 Apr '19

26 Apr '19

I have noticed after full power failiure (all nodes simultaneously - labs don't have UPS yet) one of my VMs was in that state, and I had to restart VDSM in order the engine to notice the crash. Definitely , there is something phishy here... I guess Sahina & Sandro can take a look in your case..

Ovirt 4.3.2 VM Failover
by michael＠wanderingmad.com 26 Apr '19

26 Apr '19

Is there something in the 4.3.x series that has changed when it comes to VM failover? I have the cluster configurated to automatically migrate all server VMs, but whenever One of the nodes goes down, all the VMs that were on that host switch to a ? status and I have to go and click "host has been rebooted" to have them failed over.

All Windows vms report "Actual timezone in guest doesn't match configuration"
by michael＠wanderingmad.com 25 Apr '19

25 Apr '19

All of my windows VMs have a yellow exclamation point with the timezone error. The configuration in ovirt says eastern time, and I've tried changing the VM from eastern time to US eastern time, and error does not go away. This is with the latest ovirt guest tools for windows.

Adding network to VM - What stupid thing have I missed?
by eshwayri＠gmail.com 25 Apr '19

25 Apr '19

When creating a new VM, it looks like I connect it's nic(s) under the "Instantiate VM network interfaces by picking a vNIC profile." setting. The problem I am seeing is that the drop down only has "Empty" and "br-kvm-prod" (my production bridge). I should have two more. Under Networks and vNIC Profiles tabs, I also have a br-kvm-stor and kvm_heart-22 defined which don't appear in that list. Am I missing something I need to do for these additional profiles to also appear in the drop-down? Some of my VMs will need access to the other physical networks.

New disk creation very slow after upgrade to 4.3.3
by Steffen Luitz 25 Apr '19

25 Apr '19

This is on a 3-node hyperconverged environment with glusterfs. After upgrading to oVirt 4.3.3 (from 4.3.2) creating a new disk takes very long (hours for a 100GByte disk, making it essentially impossible to create a new disk image). In the UI the default is "preallocated" but changing it to thin provision does not make any difference. Regardless of this setting, an fallocate process gets started on the SDM host: /usr/bin/python2 /usr/libexec/vdsm/fallocate 107374182400 /rhev/data-center/mnt/glusterSD/s-vmhost2-ovir.t... Using fallocate to create a file directly on the underlying file system is fast. Using it to create a file through the glusterfs fuse mount is very slow. Thanks for any insights. Steffen
