vm.conf on one of the node is missing
by knarra 25 Nov '16

25 Nov '16

Hi, I have three nodes with glusterfs as storage domain. For some reason i see that vm.conf from /var/run/ovirt-hosted-engine-ha is missing and due to this on one of my host i see that Hosted Engine HA : Not Active. Once i copy the file from some other node and restart ovirt-ha-broker and ovirt-ha-agent services everything works fine. But then this happens again. Can some please help me identify why this happens. Below is the log i see in ovirt-ha-agent.logs. https://paste.fedoraproject.org/489120/79990345/ Thanks kasturi

hi I apologize if I missed it reading release(repo) note. What are users supposed to do with EPEL repo? I'm asking for hit this: --> Package python-perf.x86_64 0:4.8.7-1.el7.elrepo will be an update --> Finished Dependency Resolution Error: Package: nfs-ganesha-gluster-2.3.0-1.el7.x86_64 (@ovirt-4.0-centos-gluster37) Requires: nfs-ganesha = 2.3.0-1.el7 Removing: nfs-ganesha-2.3.0-1.el7.x86_64 (@ovirt-4.0-centos-gluster37) nfs-ganesha = 2.3.0-1.el7 Updated By: nfs-ganesha-2.3.2-1.el7.x86_64 (epel) nfs-ganesha = 2.3.2-1.el7 and I also wander if there might be more? regards.

If I try to migrate a disk of a running VM to another storage domain it fails with the following message: Operation Cancelled Error while executing action: User is not logged in. Migrating disks of stopped VM's continues to work. Probably a bug ?

Storage questions
by Oscar Segarra 24 Nov '16

24 Nov '16

Hi, I'm planning to deploy a scalable VDI infraestructure where each phisical host can run over 100 VDIs and I'd like to deploy 10 physical hosts (1000 VDIs). In order to avoid performance problems (replicating 1000VDIs changes over gluster network I think can provoque performance problems) I have thought to use local storage for VDI assuming that VDIs cannot be migrated between phisical hosts. ¿Is my worry founded in terms of performance? ¿Is it possible to utilize local SSD storage for VDIs? I'd like to configure a gluster volume for backup on rotational disks (tiered+replica 2+ stripe=2) just to provide HA if a physical host fails. ¿Is it possible to use rsync for backing up VDIs? If not ¿How can I sync/backup the VDIs running on local storage on the gluster shared storage? If a physical host fails ¿How can I start the latest backup of the VDI on the shared gluster? Thanks a lot

Recommended Ovirt Implementation on Active-Active Datacenters (Site 1 and Site2) - Same Cluster
by Rogério Ceni Coelho 24 Nov '16

24 Nov '16

Hi Ovirt Jedi´s !!! First of all, congrats about the product !!! I love Ovirt !!! I am using Ovirt 4.0.4 with 10 hosts and 58 virtual machines on two Active-Active Datacenters using two EMC Vplex + two EMC VNX5500 + eight Dell Blades + 8 Dell PowerEdge M610 and two M620 Servers. Half servers are on Site 1 and Half servers on Site 2. The same with VMs. All Sites work as one and have redundant network, storage, power, etc etc etc ... I want to know what is the best way to set that VM number 1 runs on Site 1 and VM number 2 runs on Site 2 ? On Vmware 5.1 we use DRS Group Manager and on Hyper-V we use Custom Properties on hosts and on VMs. What we use on oVirt without segregate on two different Datacenters or two different clusters ? Thanks in advance.

Hi, I upgraded my engine host from 4.0.2.7 to 4.0.4 and when I attempt to login via a aaa provider I get: java.security.cert.CertificateExpiredException: NotAfter: Fri Nov 04 00:19:18 GMT 2016, What certificate is this referring to? The certificate from the aaa provider expires in 2063. It was fine until the upgrade. Thanks for any help, Cam

GFS2 and OCFS2 for Shared Storage
by Fernando Frediani 23 Nov '16

23 Nov '16

Has anyone managed to use GFS2 or OCFS2 for Shared Block Storage between hosts ? How scalable was it and which of the two work better ? Using traditional CLVM is far from good starting because of the lack of Thinprovision so I'm willing to consider either of the Filesystems. Thanks Fernando
