high number of IOPS from ovirt hosts
by Andrea Fagiani 14 Feb '17

14 Feb '17

Hi, We've got a 8-host cluster running oVirt 4.1; each host is connected via iscsi to a EQL 4100 storage (2x). Most of the VMs use barely any IOPS, however on our storage controller we've noticed a constant steam of reads, about 2000 IOPS; any idea what might cause the ovirt hosts to hammer on the storage so much? Looking at iotop, it seems that systemd-udevd is being activated every few seconds (and its IO% is usually fairly high) so I assume this might be somehow related. Thanks, Andrea

questions about migrating to self-hosted engine from bare-metal
by cmc 14 Feb '17

14 Feb '17

Hi, I want to migrate from a bare-metal engine to a self-hosted one. I'm following the guide at: http://www.ovirt.org/documentation/self-hosted/chap-Migrating_from_Bare_Met… I've created a new VM with el 7.3 on the existing cluster, and used an NFS share as storage on another VM, (which does not fill up). It gets most of the way through and then mentions failing to execute 'closing_ip', and fails to start the VM: [ INFO ] Creating Image for 'hosted-engine.lockspace' ... [ INFO ] Image for 'hosted-engine.lockspace' created successfully [ INFO ] Creating Image for 'hosted-engine.metadata' ... [ INFO ] Image for 'hosted-engine.metadata' created successfully [ INFO ] Creating VM Image [ INFO ] Extracting disk image from OVF archive (could take a few minutes depending on archive size) [ INFO ] Validating pre-allocated volume size [ INFO ] Uploading volume to data domain (could take a few minutes depending on archive size) [ INFO ] Image successfully imported from OVF [ INFO ] Destroying Storage Pool [ INFO ] Start monitoring domain [ INFO ] Configuring VM [ INFO ] Updating hosted-engine configuration [ INFO ] Stage: Transaction commit [ INFO ] Stage: Closing up The following network ports should be opened: tcp:5900 tcp:5901 tcp:9090 udp:5900 udp:5901 An example of the required configuration for iptables can be found at: /etc/ovirt-hosted-engine/iptables.example In order to configure firewalld, copy the files from /etc/ovirt-hosted-engine/firewalld to /etc/firewalld/services and execute the following commands: firewall-cmd -service hosted-cockpit firewall-cmd -service hosted-console [ INFO ] Creating VM [ ERROR ] Failed to execute stage 'Closing up': The VM is not powering up: please check VDSM logs [ INFO ] Stage: Clean up [ INFO ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20170213142939.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Hosted Engine deployment failed: this system is not reliable, please check the issue,fix and redeploy Log file is located at /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20170213141937-0wgc31.log In the vdsm log, it appears to be complaining about the volume not existing, but I can see it (it is on NFS) I've attached the vdsm.log and answers.conf Any help appreciated. Thanks, Cam

Updated Invitation: Deep Dive: Ansible modules for oVirt @ Tue Feb 14, 2017 4pm - 5pm (CET) (users@ovirt.org)
by omachace＠redhat.com 14 Feb '17

14 Feb '17

This event has been changed. Title: Deep Dive: Ansible modules for oVirt In this presentation will do a short introduction to Ansible. Then we will focus how to use Ansible with oVirt. Ansible 2.3 ships many oVirt modules, which can help you orchestrate your oVirt infrastructure. We will show a demo how to use them. Ansible 2.3 also ships dynamic inventory for oVirt, we will show how to use it as well.

Bandiwdth limit on a Virtual Machine
by Fernando Frediani 14 Feb '17

14 Feb '17

Hello. Is there any limitation of bandwidth for a Virtual Machine per default ? I have a host with a bonding of 3 x 1Gb and the VM is connected to that bonding. On the Engine interface on the VM status I see "Network" and it has a percentage and a tiny graph. What that percentage is related to ? 1Gb ? 3Gb ? 10Gb ? Is there anything that has to be done in order the VM can achieve speeds over 1Gbps ? Fernando

Ovirt not seeing cinder usage
by Jordan Conway 13 Feb '17

13 Feb '17

Hello, Is it normal to not see the usage of a ceph backed cinder storage domain? If not, can someone point me in the right direction to see what I should be troubleshooting, I don't see anything obvious in vdsm/engine logs. This is what I see on the general tab of the storage domain: Size:[N/A] Available:[N/A] Used:[N/A] Allocated: 690 GB Over Allocation Ratio: 0% Warning Low Space Indicator: 0% (0 GB) Critical Space Action Blocker: < 1 GB Thank you, Jordan Conway

Upgrading oVirt-Node-NG from 4.0.3 to 4.0.6
by Thomas Kendall 13 Feb '17

13 Feb '17

We recently migrated from 3.6 to 4.0, but I'm a little confused about how to keep the nodes up to date. I see the auto-updates come through for my 4.0.3 nodes, but they don't seem to upgrade them to the newer 4.0.x releases. Is there a way to do this upgrade? I have two nodes that were installed with 4.0.3, and I would like to bring them up to the same version as everything else. For reference, the 4.0.3 nodes were built off the 4.0-2016083011 iso, and the 4.0.6 nodes were built off the 4.0-2017011712 iso. Thanks, Thomas

Current state of UI brick management when using dedicated interfaces for ovirtmgmt & gluster?
by Doug Ingham 13 Feb '17

13 Feb '17

Hey Guys, I currently use dedicated interfaces & hostnames to separate gluster traffic on my "hyperconverged" hosts. For example, the first node uses "v0" for its management interface & "s0" for its gluster interface. With this setup, I notice that all functions under the "Volumes" tab work, however I'm unable to import storage domains with "Use managed gluster", and hosts' bricks aren't listed under the "Hosts" tab. My engine log is also full of entries such as this... 2017-02-10 03:25:07,155-03 WARN [org.ovirt.engine.core.vdsbroker.gluster.GlusterVolumesListReturn] (DefaultQuartzScheduler3) [78aef637] Could not add brick 's0:/gluster/data-novo/brick' to volume 'bded65c7-e79e-4bc9-9630-36a69ad2e684' - server uuid 'a9d062c6-7d01-404f-ab0c-3ed468e60c91' not found in cluster '00000002-0002-0002-0002-00000000017a' 2017-02-10 03:25:09,157-03 WARN [org.ovirt.engine.core.vdsbroker.gluster.GlusterVolumesHealInfoReturn] (DefaultQuartzScheduler10) [6828f9a7] Could not fetch heal info for brick 's0:/gluster/data-novo/brick' - server uuid 'a9d062c6-7d01-404f-ab0c-3ed468e60c91' not found I'm wondering whether the different hostnames used to configure each of the interfaces is casuing the confusion? So...is there something wrong, or is this still an unsupported configuration? Cheers, -- Doug

Issue with Moving Disks
by Bryan Sockel 13 Feb '17

13 Feb '17

Hi, I attempted to move a few disks from a glusterFS to an ISCSI file system. I have number of errors during the process, and it looks like a few of the disk moves are hung. They are hung at various percentages. in the events, it says moving Disk X from A to B, validation completes but i copying volume returns with an error. Is there a way to kill the move process so i can have access back to the VM's? Thanks
