How to mount/use a shareable disk
by Jayme Fall 09 Nov '17

09 Nov '17

I’m playing around with shared disks in ovirt to allow a couple of vm’s to access the same data. I created a new disk that is shareable and attached it to one of my CentOS vms but I don’t understand how to actually make use of the shared disk. It does not show up as a mounted disk on the Centos VM. How do I actually use this shared disk from within my VM, or am I mis-understanding its purpose? Thanks!

can't migrate Windows 2012R2 VM
by Matthias Leopold 09 Nov '17

09 Nov '17

Hi, i'm experiencing reproducible problems migrating Windows 2012R2 VMs in oVirt 4.1 environments. I can't migrate two different Windows 2012R2 VMs in two different oVirt environments. engine.log in this situation is the same in both cases, i'm attaching it. lines like "Failed to destroy VM 'd4ddd4d1-2de4-4ace-900d-76552cadefb0' because VM does not exist, ignoring" "VM 'd4ddd4d1-2de4-4ace-900d-76552cadefb0'(ovirt-test03_win2012) was unexpectedly detected as 'Down' on VDS 'xxx'" don't sound too confidence-inspiring. Windows 2008 and Windows 2016 VMs can be migrated with no problem. - oVirt version is 4.1.6 - VirtIO drivers and oVirt guest agent in windows guest were installed from oVirt-toolsSetup-4.1-5.fc24.iso (one VM is using VirtIO devices, other VM isn't) - oVirt cluster migration settings are default in a 4.1 install (migration policy: legacy, i also tried: minimal downtime, post copy migration, no avail...) thx for any advice matthias

Hosted Engine installation + GlusterFS cluster
by Artem Tambovskiy 09 Nov '17

09 Nov '17

Another yet attempt to get a help on hosted-engine deployment with glusterfs cluster. I already spend a day trying to get bring such a setup to work with no luck. The hosted engine being successfully deployed but I can't activate the host, the storage domain for the host is missing and I can't even add it. So either something went wrong during deployment or my glusterfs cluster doesn't configured properly. That are the prerequisites for this? - glusterfs cluster of 3 nodes with replica 3 volume - Any specific volume configs? - how many volumes should I prepare for hosted engine deployment? Any other thoughts? Regards, Artem

Re: [ovirt-users] glusterFS is not independent?
by Johan Bernhardsson 09 Nov '17

Gluster would be to overcomplicate this if you only want local storage on both to be reachable over the network. Simplest way is to setup an nf server on both nodes and create a storage domain for each. Gluster is a way to secure your data and replicate them over several nodes. so that if one node goes down or explodes you always have the data replicated to other nodes. Running a single brick gluster volume is not recomended. /JohanOn Thu, 2017-11-09 at 11:57 +0100, Jon bae wrote: > Thank you for your answer! > > I don't understand way I have to put them in replicate mode.

glusterFS is not independent?
by Jon bae 09 Nov '17

09 Nov '17

Hello, I'm very new to oVirt and glusterFS, so maybe I got something wrong... I have the oVirt engine installed on a separate server and I have also two physical nodes. On every node I configure glusterFS, the volume is in distribution mode and have only one brick, from is one node. Both volumes I also add to its own storage domain. The idea was, that both storage domains are independent from each other, that I can turn of one node and only turn it on, when I need it. But now I have the problem, that when I turn of on node, both storage domains goes down. and the volume shows the the brick is not available. Is there a way to fix this? Regards Jonathan
