ovirt 4.1 hosted engine hyper converged on glusterfs 3.8.10 : "engine" storage domain alway complain about "unsynced" elements
by yayo (j) 08 Sep '17

Hi all, We have an ovirt cluster hyperconverged with hosted engine on 3 full replicated node . This cluster have 2 gluster volume: - data: volume for the Data (Master) Domain (For vm) - engine: volume fro the hosted_storage Domain (for hosted engine) We have this problem: "engine" gluster volume have always unsynced elements and we cant' fix the problem, on command line we have tried to use the "heal" command but elements remain always unsynced .... Below the heal command "status": [root@node01 ~]# gluster volume heal engine info Brick node01:/gluster/engine/brick /.shard/8aa74564-6740-403e-ad51-f56d9ca5d7a7.48 /.shard/8aa74564-6740-403e-ad51-f56d9ca5d7a7.64 /.shard/8aa74564-6740-403e-ad51-f56d9ca5d7a7.60 /.shard/8aa74564-6740-403e-ad51-f56d9ca5d7a7.2 /.shard/8aa74564-6740-403e-ad51-f56d9ca5d7a7.68 /8f215dd2-8531-4a4f-b6ed-ea789dd8821b/images/19d71267-52a4-42a3-bb1e-e3145361c0c2/7a215635-02f3-47db-80db-8b689c6a8f01 /8f215dd2-8531-4a4f-b6ed-ea789dd8821b/images/88d41053-a257-4272-9e2e-2f3de0743b81/6573ed08-d3ed-4d12-9227-2c95941e1ad6 /.shard/8aa74564-6740-403e-ad51-f56d9ca5d7a7.61 /.shard/8aa74564-6740-403e-ad51-f56d9ca5d7a7.1 /8f215dd2-8531-4a4f-b6ed-ea789dd8821b/dom_md/ids /.shard/8aa74564-6740-403e-ad51-f56d9ca5d7a7.20 /__DIRECT_IO_TEST__ Status: Connected Number of entries: 12 Brick node02:/gluster/engine/brick /8f215dd2-8531-4a4f-b6ed-ea789dd8821b/images/19d71267-52a4-42a3-bb1e-e3145361c0c2/7a215635-02f3-47db-80db-8b689c6a8f01 <gfid:9a601373-bbaa-44d8-b396-f0b9b12c026f> /8f215dd2-8531-4a4f-b6ed-ea789dd8821b/dom_md/ids <gfid:1e309376-c62e-424f-9857-f9a0c3a729bf> <gfid:e3565b50-1495-4e5b-ae88-3bceca47b7d9> <gfid:4e33ac33-dddb-4e29-b4a3-51770b81166a> /__DIRECT_IO_TEST__ <gfid:67606789-1f34-4c15-86b8-c0d05b07f187> <gfid:9ef88647-cfe6-4a35-a38c-a5173c9e8fc0> /8f215dd2-8531-4a4f-b6ed-ea789dd8821b/images/88d41053-a257-4272-9e2e-2f3de0743b81/6573ed08-d3ed-4d12-9227-2c95941e1ad6 <gfid:9ad720b2-507d-4830-8294-ec8adee6d384> <gfid:d9853e5d-a2bf-4cee-8b39-7781a98033cf> Status: Connected Number of entries: 12 Brick node04:/gluster/engine/brick Status: Connected Number of entries: 0 running the "gluster volume heal engine" don't solve the problem... Some extra info: We have recently changed the gluster from: 2 (full repliacated) + 1 arbiter to 3 full replicated cluster but i don't know this is the problem... The "data" volume is good and healty and have no unsynced entry. Ovirt refuse to put the node02 and node01 in "maintenance mode" and complains about "unsynced elements" How can I fix this? Thank you

imageio: Error setting ImageProxyAddress's value. No such entry with version general.

oVirt 4.1.4 - engine-setup of imageio proxy on a host, at the end it requires: engine-config -s ImageProxyAddress=xxxxxxxx:54323 But on engine: Error setting ImageProxyAddress's value. No such entry with version general. Any ideas thanks! -- Richard Chan

oVIRT Node / Network Manager / oVirt 4.1
by Devin Acosta 14 Aug '17

14 Aug '17

I noticed that for some reason when I am running oVirt node on my hosts and disabled NetworkManager it appears that it kept turning itself back on, and my understanding is that Network Manager should be disabled. I had to force remove Network Manager in order to get it to stay disabled. I have been seeing strangeness with my VM's where they disconnect, and where hosted-engine keeps trying to non-stop migrate to another host. Just wanted to first confirm about Network Manager and oVirt Node image. -- Devin Acosta Red Hat Certified Architect

Problemas with ovirtmgmt network used to connect VMs
by FERNANDO FREDIANI 08 Aug '17

08 Aug '17

Has anyone had problem when using the ovirtmgmt bridge to connect VMs ? I am still facing a bizarre problem where some VMs connected to this bridge stop passing traffic. Checking the problem further I see its mac address stops being learned by the bridge and the problem is resolved only with a VM reboot. When I last saw the problem I run brctl showmacs ovirtmgmt and it shows me the VM's mac adress with agening timer 200.19. After the VM reboot I see the same mac with agening timer 0.00. I don't see it in another environment where the ovirtmgmt is not used for VMs. Does anyone have any clue about this type of behavior ? Fernando

supervdsmd IOError to /dev/stdout
by Richard Chan 03 Aug '17

03 Aug '17

After an upgrade to 4.0 I have a single host that cannot start supervdsmd because of IOError on /dev/stdout. All other hosts upgraded correctly. In the systemd unit I have to hack StandardOutput=null. Any thing I have overlooked? The hosts are all identical and it is just this one that has this weird behaviour. -- Richard Chan

sanlock ids file broken after server crash
by Johan Bernhardsson 02 Aug '17

02 Aug '17

Hello, The ids file for sanlock is broken on one setup. The first host id in the file is wrong. >From the logfile i have: verify_leader 1 wrong space name 0924ff77-ef51-435b-b90d-50bfbf2e�ke7 0924ff77-ef51-435b-b90d-50bfbf2e8de7 /rhev/data-center/mnt/glusterSD/ Note the broken char in the space name. This also apears. And it seams as the hostid too is broken in the ids file: leader4 sn 0924ff77-ef51-435b-b90d-50bfbf2e�ke7 rn ��7afa5-3a91-415b- a04c-221d3e060163.vbgkvm01.a ts 4351980 cs eefa4dd7 Note the broken chars there as well. If i check the ids file with less or strings the first row where my vbgkvm01 host are. That has broken chars. Can this be repaired in some way without taking down all the virtual machines on that storage? /Johan

VDSM Command failed: Heartbeat Exceeded
by Neil 02 Aug '17

02 Aug '17

Hi guys, Please could someone assist me, my DC seems to be trying to re-negotiate SPM and apparently it's failing. I tried to delete an old autogenerated snapshot and shortly after that the issue seemed to start, however after about an hour, the snapshot said successfully deleted, and then SPM negotiated again albeit for a short period before it started trying to re-negotiate again. Last week I upgraded from ovirt 3.5 to 3.6, I also upgraded one of my 4 hosts using the 3.6 repo to the latest available from that repo and did a yum update too. I have 4 nodes and my ovirt engine is a KVM guest on another physical machine on the network. I'm using an FC SAN with ATTO HBA's and recently we've started seeing some degraded IO. The SAN appears to be alright and the disks all seem to check out, but we are having rather slow IOPS at the moment, which we trying to track down. ovirt engine CentOS release 6.9 (Final) ebay-cors-filter-1.0.1-0.1.ovirt.el6.noarch ovirt-engine-3.6.7.5-1.el6.noarch ovirt-engine-backend-3.6.7.5-1.el6.noarch ovirt-engine-cli-3.6.2.0-1.el6.noarch ovirt-engine-dbscripts-3.6.7.5-1.el6.noarch ovirt-engine-extension-aaa-jdbc-1.0.7-1.el6.noarch ovirt-engine-extensions-api-impl-3.6.7.5-1.el6.noarch ovirt-engine-jboss-as-7.1.1-1.el6.x86_64 ovirt-engine-lib-3.6.7.5-1.el6.noarch ovirt-engine-restapi-3.6.7.5-1.el6.noarch ovirt-engine-sdk-python-3.6.7.0-1.el6.noarch ovirt-engine-setup-3.6.7.5-1.el6.noarch ovirt-engine-setup-base-3.6.7.5-1.el6.noarch ovirt-engine-setup-plugin-ovirt-engine-3.6.7.5-1.el6.noarch ovirt-engine-setup-plugin-ovirt-engine-common-3.6.7.5-1.el6.noarch ovirt-engine-setup-plugin-vmconsole-proxy-helper-3.6.7.5-1.el6.noarch ovirt-engine-setup-plugin-websocket-proxy-3.6.7.5-1.el6.noarch ovirt-engine-tools-3.6.7.5-1.el6.noarch ovirt-engine-tools-backup-3.6.7.5-1.el6.noarch ovirt-engine-userportal-3.6.7.5-1.el6.noarch ovirt-engine-vmconsole-proxy-helper-3.6.7.5-1.el6.noarch ovirt-engine-webadmin-portal-3.6.7.5-1.el6.noarch ovirt-engine-websocket-proxy-3.6.7.5-1.el6.noarch ovirt-engine-wildfly-8.2.1-1.el6.x86_64 ovirt-engine-wildfly-overlay-8.0.5-1.el6.noarch ovirt-host-deploy-1.4.1-1.el6.noarch ovirt-host-deploy-java-1.4.1-1.el6.noarch ovirt-image-uploader-3.6.0-1.el6.noarch ovirt-iso-uploader-3.6.0-1.el6.noarch ovirt-release34-1.0.3-1.noarch ovirt-release35-006-1.noarch ovirt-release36-3.6.7-1.noarch ovirt-setup-lib-1.0.1-1.el6.noarch ovirt-vmconsole-1.0.2-1.el6.noarch ovirt-vmconsole-proxy-1.0.2-1.el6.noarch node01 (CentOS 6.9) vdsm-4.16.30-0.el6.x86_64 vdsm-cli-4.16.30-0.el6.noarch vdsm-jsonrpc-4.16.30-0.el6.noarch vdsm-python-4.16.30-0.el6.noarch vdsm-python-zombiereaper-4.16.30-0.el6.noarch vdsm-xmlrpc-4.16.30-0.el6.noarch vdsm-yajsonrpc-4.16.30-0.el6.noarch gpxe-roms-qemu-0.9.7-6.16.el6.noarch qemu-img-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-tools-0.12.1.2-2.479.el6_7.2.x86_64 libvirt-0.10.2-62.el6.x86_64 libvirt-client-0.10.2-62.el6.x86_64 libvirt-lock-sanlock-0.10.2-62.el6.x86_64 libvirt-python-0.10.2-62.el6.x86_64 node01 was upgraded out of desperation after I tried changing my DC and cluster version to 3.6, but then found that none of my hosts could be activated out of maintenance due to an incompatibility with 3.6 (I'm still not sure why as searching seemed to indicate Centos 6.x was compatible. I then had to remove all 4 hosts, and change the cluster version back to 3.5 and then re-add them. When I tried changing the cluster version to 3.6 I did get a complaint about using the "legacy protocol" so on each host under Advanced, I changed them to use the JSON protocol, and this seemed to resolve it, however once changing the DC/Cluster back to 3.5 the option to change the protocol back to Legacy is no longer shown. node02 (Centos 6.7) vdsm-4.16.30-0.el6.x86_64 vdsm-cli-4.16.30-0.el6.noarch vdsm-jsonrpc-4.16.30-0.el6.noarch vdsm-python-4.16.30-0.el6.noarch vdsm-python-zombiereaper-4.16.30-0.el6.noarch vdsm-xmlrpc-4.16.30-0.el6.noarch vdsm-yajsonrpc-4.16.30-0.el6.noarch gpxe-roms-qemu-0.9.7-6.14.el6.noarch qemu-img-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-tools-0.12.1.2-2.479.el6_7.2.x86_64 libvirt-0.10.2-54.el6_7.6.x86_64 libvirt-client-0.10.2-54.el6_7.6.x86_64 libvirt-lock-sanlock-0.10.2-54.el6_7.6.x86_64 libvirt-python-0.10.2-54.el6_7.6.x86_64 node03 CentOS 6.7 vdsm-4.16.30-0.el6.x86_64 vdsm-cli-4.16.30-0.el6.noarch vdsm-jsonrpc-4.16.30-0.el6.noarch vdsm-python-4.16.30-0.el6.noarch vdsm-python-zombiereaper-4.16.30-0.el6.noarch vdsm-xmlrpc-4.16.30-0.el6.noarch vdsm-yajsonrpc-4.16.30-0.el6.noarch gpxe-roms-qemu-0.9.7-6.14.el6.noarch qemu-img-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-tools-0.12.1.2-2.479.el6_7.2.x86_64 libvirt-0.10.2-54.el6_7.6.x86_64 libvirt-client-0.10.2-54.el6_7.6.x86_64 libvirt-lock-sanlock-0.10.2-54.el6_7.6.x86_64 libvirt-python-0.10.2-54.el6_7.6.x86_64 node04 (Centos 6.7) vdsm-4.16.20-1.git3a90f62.el6.x86_64 vdsm-cli-4.16.20-1.git3a90f62.el6.noarch vdsm-jsonrpc-4.16.20-1.git3a90f62.el6.noarch vdsm-python-4.16.20-1.git3a90f62.el6.noarch vdsm-python-zombiereaper-4.16.20-1.git3a90f62.el6.noarch vdsm-xmlrpc-4.16.20-1.git3a90f62.el6.noarch vdsm-yajsonrpc-4.16.20-1.git3a90f62.el6.noarch gpxe-roms-qemu-0.9.7-6.15.el6.noarch qemu-img-0.12.1.2-2.491.el6_8.1.x86_64 qemu-kvm-0.12.1.2-2.491.el6_8.1.x86_64 qemu-kvm-tools-0.12.1.2-2.503.el6_9.3.x86_64 libvirt-0.10.2-60.el6.x86_64 libvirt-client-0.10.2-60.el6.x86_64 libvirt-lock-sanlock-0.10.2-60.el6.x86_64 libvirt-python-0.10.2-60.el6.x86_64 I'm seeing a rather confusing error in the /var/log/messages on all 4 hosts as follows....

We are in the process of expanding the SAN Array too, but we trying to get to the bottom of the bad IOPS at the moment before adding on addition overhead. Ping tests between hosts and engine all look alright, so I don't suspect network issues. I know this is very vague, everything is currently operational, however as you can see in the attached logs, I'm getting lots of ERROR messages. Any help or guidance is greatly appreciated. Thanks. Regards. Neil Wilson.

oVirt and Foreman
by Davide Ferrari 02 Aug '17

02 Aug '17

Hello list is anybody successfully using oVirt + Foreman for VM creation + provisioning? I'm using Foremn (latest version, 1.15.2) with latest oVirt version (4.1.3) but I'm encountering several problem, especially related to disks. For example: - cannot create a VM with multiple disks though Foreman CLI (hammer) - if I create a multidisk VM from Foreman, the second disk always gets the "bootable" flag and not the primary image, making the VMs not bootable at all. Any other Foreman user sharing the pain here? Foramn's list is not so useful so I'm trying to ask here. How do you programmatically create virtual machines with oVirt and Foreman? Should I switch do directly using oVirt API? Thanks in advance Davide

Deploying training lab
by Andy Michielsen 01 Aug '17

01 Aug '17

Hello all, Don't know if this is the right place to ask this but I would like to set up a trainingslab with oVirt. I have deployed an engine and a host with local storage and want to run 1 server and 5 desktops off it. But the desktops will be used on thin clients or old laptops with some minimal os installation running spice client or a webbrowser. I was wondering if anyone can give me pointer in how to set up a minimal laptop which only need to run an spice client. Kind regards.
