Resize FC LUN in SD
by Arsène Gschwind 22 Jul '15

22 Jul '15

Hi, I'm trying to online resize a FC LUN in a storagedomain, i could resize the LUN on system level and resize the PV on all hosts in my cluster but after a while oVirt set the LUN to "inactive" . Is there a way to inform vdsm to rescan and update the LUN informations? I've read that this feature will be available in version 3.6 but I'm wondering if it would be possible in version 3.5 using some system commands/calls. Thanks for any hint. Rgds, Arsène

Re: [ovirt-users] oVirt 3.5.3 Host Network Interfaces
by Soeren Malchow 21 Jul '15

Dear Michael, The network scripts look exactly as we did that, and then during setting up the host network we also got the “already enslaved” message which did not cause a problem since it actually was enslaved, afterwards there were proper vdsm generated interface files. Though we have the difference, that the ovirt already showed the bond even when it was not managed by ovirt yet. You can still change the one bonded interface in ovirt and add one additional interface, just drag and drop, put the bridge in and configured the Ips, however, if you want 802.3ad you need to change the switch ports to do 802.3ad as well a little bit after you applied the change, to avoid having to do the switch configuration use “custom” and “mode=5” or “mode=6” Regards Soeren On 07/07/15 01:14, "Prof. Dr. Michael Schefczyk" <michael(a)schefczyk.net> wrote: >Dear Soeren, dear all, > >Thank you very much.

Cannot run specific VM in one node
by Diego Remolina 21 Jul '15

21 Jul '15

Hi, Was wondering if I can get some help with this particular situation. I have two ovirt cluster nodes. I had a VM running in node2 and tried to move it to node1. The move failed and the machine was created and paused in both nodes. I tried stopping migration, shutting down the machine, etc but none of that worked. So I decided to simply look for the process number and I killed it for that VM. After that, I was not able to get the VM to run in any of the nodes, so I rebooted them both. At this point, the vm will *not* start in node2 at all. When I try to start it, it just sits there and if I do: virsh -r list from the command line, the output says the vm state is "shut off". I am able to user Run Once to fire up the VM in node 1, but I cannot migrate it to node2. How can I clear this problematic state for node 2? Thanks, Diego

Setting VmPool type via ovirtsdk
by nicolas＠devels.es 20 Jul '15

20 Jul '15

Hi, I'm defining new VmPools via python code using ovirtSDK along with oVirt v. 3.5.3.1-1. Pool creation seems to work fine, but by default they are created as 'Automatic' and I need them to be 'Manual', however, I can't find out the SDK parameter to do this. Is this currently possible? Thanks. Regards.

Stuck removing DataCenter, Hosts and Volumes
by ml＠ohnewald.net 19 Jul '15

19 Jul '15

Hello List, I have a 2 node replica Gluster Cluster in a Datacenter which i want to remove completely. 1.) I put both nodes in maintenance and removed the DataCenter and the Storage unter the Storage Tab. But now i am stuck removing the Cluster, Hosts and GlusterVolume. a) When i try to remove the Cluster: Error while executing action: Cannot remove Cluster. Host Cluster contains one or more Hosts. b) When i try to remove the hosts: node1: Cannot remove Host. Server having Gluster volume. c) When i try to remove my Volume i get: Error while executing action: Cannot stop Gluster Volume. No up server found in Cluster_II. Any idea how to solve this? Thanks, Mario
