[Users] proper way to move nfs data storage domain?
by David Smith 21 Mar '14

21 Mar '14

Two examples; 1) I need to move the nfs data domain to a new server, whats the best way? 2) I think this applies the same as above, if I need to rename the nfs server hostname, whats the best way? I managed to "export/import" the export and iso domains and have them up and running on the new server, however, since you can't import a data domain, i'm wondering whats the best method for this. thanks

[Users] Clone from Snapshot
by Tejesh M 20 Mar '14

20 Mar '14

Hi, I'm trying to clone a VM from snapshot with the below code. but it is not cloning.. org.ovirt.engine.sdk.decorators.VM vm2 = api.getVMs().get("testVM"); VM cloneVM = new VM(); cloneVM.setName("MyClonedViaAPI"); VMSnapshot snap3 = new VMSnapshot(null); snap3 = vm2.getSnapshots().get(UUID.fromString("7799ce3f-a007-415a-84c5-df323e8f440d")); Action act = new Action(); act.setClone(true); act.setVm(cloneVM); snap3.restore(act); Actually, my original goal is to Clone VM directly from another VM instead of cloning from snapshot. Can you help me? -- Thanks & Regards Tejesh

[Users] Changing IP address of NFS storage server
by René Koch 20 Mar '14

20 Mar '14

Hi, I have an old oVirt 3.2 setup and I have to change the ip address of the data storage domain (NFS). Even if I shut down all vms I can't detach the data storage domain and reimport it as vms and templates are configured in oVirt which have their disk on this storage domain. Is there a way to change the ip? Maybe using the database? Would this be possible in 3.3 or 3.4? Thanks a lot for tips! -- Best Regards René Koch Senior Solution Architect ============================================ LIS-Linuxland GmbH Brünner Straße 163, A-1210 Vienna Phone: +43 1 236 91 60 Mobile: +43 660 / 512 21 31 E-Mail: rkoch(a)linuxland.at ============================================

[Users] Ovirt 3.3.3 to 3.3.4 upgrade issues Centos 6
by Gary Lloyd 20 Mar '14

20 Mar '14

I have tested an upgrade from engine 3.3.3 to 3.3.4 under centos 6. It seems that the vdsm nodes are now showing as non-operational and the only way I have been able to cure this was to: - Upgrade the vdsm version on a node to 4.13.3-4 - install vdsm-gluster - start glusterd service We are only currently using ISCSI. I cannot get a node running vdsm-4.13.3-3 to show as being operational under engine 3.3.4 Has anyone been able to get 3.3.4 functioning with previous version vdsm nodes ? This issue may hinder our progress when it comes time to upgrade our production engine / nodes when putting hosts into maintenance mode and performing migrations etc. Thanks *Gary Lloyd* ---------------------------------- IT Services Keele University -----------------------------------

The vm/hosts statistics are gathered and provided by VDSM. Anyway I would leave this part out at the moment. The virt-sparsify command is a long running task and in the current architecture it can be only an SPM task. There is some ongoing work to remove the pool and the SPM (making virt-sparsify operable by any host) but I wouldn't block on that. > I am also not very clear about the Shared Storage component in the > architecture.

If the Storage solution is necessarily a NAS > instance, then virt-sparsify on NFS mount is the only option. The storage connections are already managed by vdsm and the volume chains are maintained transparently in /rhev/data-center/... There are few differences between image files on NFS/Gluster and images stored on LVs but with regard to how to reach them it is transparent (similar path). > Right now, I am in the process of setting up oVirt on my system, and > getting more familiar with the architecture.

Depending on the amount of time that you can dedicate to this project it seems that you could tackle both the vdsm and ovirt-engine parts. -- Federico

I tried oVirt Node - 3.0.4 - 1.0.2014012912 but had problems with VDSM comp= atibility (VDSM version (4.14) and cannot join cluster - cluster is compat= ible with VDSM versions [4.13, 4.9, 4.11, 4.12, 4.10].) I now see this ment= ioned in https://bugzilla.redhat.com/show_bug.cgi?id=3D1067096#c0 I did try upgrading Engine to 3.3.4-1.el6 but still see the same VDSM 4.14 = problem. I also tried building the iso (as per http://www.ovirt.org/Node_Building) a= nd could see that it was downloading the qemu-kvm-rhev (which I think is ne= eded to enable the live snapshot functionality). However I got stuck adding= the vdsm plugin as the iso was being built with the 3.4.0.57rhs versions o= f the glusterfs packages whereas the plugin was dependant on glusterfs 3.4= .0-8. I already have a working Engine (3.3.2-1.el6) and Node (3.0.1 - 1.0.2.el6) = test configuration but would very much like to be able to add the live snap= shot functionality.
