Hi, Does virt-v2v command work with glusterfs storage domain. I have an OVA image and that needs to be imported to glusterfs storage domain. Please provide some pointers to this. Thanks and Regards, Ram

oVirt Node 4.1.2 offering RC update?
by Vinícius Ferrão 11 Jul '17

11 Jul '17

Hello, I’ve noted a strange thing on oVirt. On the Hosted Engine an update was offered and I was a bit confused, since I’m running the latest oVirt Node release. To check if 4.1.3 was already released I issued an “yum update” on the command line and for my surprise an RC release was offered. This not seems to be right: ====================================================================================================================== Package Arch Version Repository Size ====================================================================================================================== Installing: ovirt-node-ng-image-update noarch 4.1.3-0.3.rc3.20170622082156.git47b4302.el7.centos ovirt-4.1 544 M replacing ovirt-node-ng-image-update-placeholder.noarch 4.1.2-1.el7.centos Updating: ovirt-engine-appliance noarch 4.1-20170622.1.el7.centos ovirt-4.1 967 M Transaction Summary ====================================================================================================================== Install 1 Package Upgrade 1 Package Total download size: 1.5 G Is this ok [y/d/N]: N Is this normal behavior? This isn’t really good, since it can lead to stable to unstable moves on production. If this is normal, how can we avoid it? Thanks, V.

Well the stack trace is in the oVirt code, so I guess it's an oVirt problem. Adding ovirt-users mailing list.

SQL : last time halted?
by Nicolas Ecarnot 09 Jul '17

Hello, I'm trying to find a way to clean up the VMs list of my DCs. I think some of my users have created VM they're not using anymore, but it's difficult to sort them out. In some cases, I can shutdown some of them and wait. Is there somewhere stored in the db tables the date of the last VM exctinction? Thank you. -- Nicolas ECARNOT

Very poor GlusterFS performance
by Chris Boot 09 Jul '17

09 Jul '17

Hi folks, I have 3x servers in a "hyper-converged" oVirt 4.1.2 + GlusterFS 3.10 configuration. My VMs run off a replica 3 arbiter 1 volume comprised of 6 bricks, which themselves live on two SSDs in each of the servers (one brick per SSD). The bricks are XFS on LVM thin volumes straight onto the SSDs. Connectivity is 10G Ethernet. Performance within the VMs is pretty terrible. I experience very low throughput and random IO is really bad: it feels like a latency issue. On my oVirt nodes the SSDs are not generally very busy. The 10G network seems to run without errors (iperf3 gives bandwidth measurements of >= 9.20 Gbits/sec between the three servers). To put this into perspective: I was getting better behaviour from NFS4 on a gigabit connection than I am with GlusterFS on 10G: that doesn't feel right at all. My volume configuration looks like this: Volume Name: vmssd Type: Distributed-Replicate Volume ID: d5a5ddd1-a140-4e0d-b514-701cfe464853 Status: Started Snapshot Count: 0 Number of Bricks: 2 x (2 + 1) = 6 Transport-type: tcp Bricks: Brick1: ovirt3:/gluster/ssd0_vmssd/brick Brick2: ovirt1:/gluster/ssd0_vmssd/brick Brick3: ovirt2:/gluster/ssd0_vmssd/brick (arbiter) Brick4: ovirt3:/gluster/ssd1_vmssd/brick Brick5: ovirt1:/gluster/ssd1_vmssd/brick Brick6: ovirt2:/gluster/ssd1_vmssd/brick (arbiter) Options Reconfigured: nfs.disable: on transport.address-family: inet6 performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.stat-prefetch: off performance.low-prio-threads: 32 network.remote-dio: off cluster.eager-lock: enable cluster.quorum-type: auto cluster.server-quorum-type: server cluster.data-self-heal-algorithm: full cluster.locking-scheme: granular cluster.shd-max-threads: 8 cluster.shd-wait-qlength: 10000 features.shard: on user.cifs: off storage.owner-uid: 36 storage.owner-gid: 36 features.shard-block-size: 128MB performance.strict-o-direct: on network.ping-timeout: 30 cluster.granular-entry-heal: enable I would really appreciate some guidance on this to try to improve things because at this rate I will need to reconsider using GlusterFS altogether.
