live snapshot merge missing after vdsm update

--_000_DBXPR06MB544F4ED5888DED7D2252803C3300DBXPR06MB544eurprd_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi all, 1 of our older clusters in use, consists of 2 nodes contain Fedora 20, with= the virt-preview repository enabled. The Engine itself is installed on a dedicated server (CentOS 6) and is stil= l on version 3.5.1.1-1.el6. During some maintenance a couple of days ago on the Fedora 20 nodes, also = the installed vdsm package was updated by the engineer working on the nodes= . We went from version 'vdsm-4.16.10-8.gitc937927.fc20' to 'vdsm-4.16.26-0.fc= 20'. This morning I wanted to remove some old snapshots on running vm's, only to= find out that the delete button is once again greyed out. I also created a new snapshot on a running vm to test if it would only happ= en on snapshots that were already there before the update, but the delete b= utton would still remain greyed out. Only turning off the vm allows me to use the delete button. When looking at the nodes within the cluster, they both still have Live Sna= pshot Support on Active. Before the vdsm update, the live merge functionality worked perfectly. Anybody experienced something similar? Could It be because the Engine is still running on 3.5.1? We are also running 2 clusters with F21 nodes that have the same vdsm versi= on nummer installed and they don't have an issue at all; connected to the s= ame engine.

oVirt Engine redundant ?

13 Oct '15

--=_b5ae4dd5edb7f3efcaaf1d71e197ef06 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII Hello I got a question regarding the redundancy of oVirt Engine; where we can control everything through the GUI; aka the vCenter. Initially; my setup was on a single server; installed following the doc AllinOne. Then after; i figured out that i would need redundancy; so i installed a second node. my question is about the vCenter; is it possible to start it on the second node when the first node is down or in maintenance ? how to ensure it is replicated ? i see there is a postgres DB on first node; but not on second node. I'm a bit worried. So, is it possible to have a dormant/slave ovirt ENGINE (oVirt web GUI ) ; and if yes, could you point me to the related documentation as i didn't find it. Maybe, it is possible to run it in a VM ? is it a good idea ? and is it still possible to migrate ?

Best practice
by Fernando Fuentes 12 Oct '15

12 Oct '15

Is there a best practice when upgrading from ovirt 3.4 to 3.5? I upgraded my development server which is a self hosted server and I just did a regular update without putting anything under maintenance... Though my vm's where turned off. The migration from krb/ldap to AAA went smoothly and so far is running like a champ. I am about to do the same to our production cluster and was wondering if I must put all Hosts under maintenance before I do the upgrade? Thanks in advance for all/any tips from the mailing list!

upgrade path from Ovirt 3.5x to 3.6x
by Andrea Ghelardi 12 Oct '15

12 Oct '15

Hallo, I needed a quick confirmation on this subject. Our environment is Ovirt 3.511 (yes, I’ll upgrade soon, I know) running on a Centos 6.6 hosted engine VM on a cluster of Centos 6.6 physical servers. Since Ovirt 3.6x will be compatible with Centos 7 hypervisor only, how I’m supposed to upgrade hosted engine, VM and HOSTs? i.e. readme tells us the well known procedure (put hosted eng in maintenance, upgrade, etc) but I will eventually end in a scenario where my hosted engine 3.6 will run on centos 7 VM running (on) a lot of centos 6.6 servers... Please tell me I have not to create a totally different datacenter and export -> import all VMs... Thank you! Andrea Ghelardi

ovirt repos dependencies
by Nathanaël Blanchet 12 Oct '15

12 Oct '15

Hello, I tried to install a single host with a custom repo synced by my own from official ovirt, gluster repos etc... (with katello). But installation always fail because otopi can't locate gluster packages, while those packages are available and can be yum installed on the host. So, what does otopi require more than gluster repo for a successfull installation? This limitation prevents from anyone to install a host from an other repo than official ones (in my case, using a katello subscription) -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

ovirt repository in the foreman host provisionning process
by Nathanaël Blanchet 12 Oct '15

12 Oct '15

Hello, In the foreman host provisionning process, should the "yum localinstall http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm" be automatically executed in the same way as it is in a traditional way? it seems that whithout those repos, vdsm installation fails, even if the host had been previously registered with katello to a local ovirt repository. Could you please help me on that point? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr
