Is teamd supported on 4.3?
by Valentin Bajrami 14 May '19

14 May '19

Hello guys, Next week, I'm planning to deploy ovirt-node 4.3 on a few hosts. I've been running bonds for the past years but I'd like to know if teaming (teamd) is also supported with this version. My current package version(s): OS Version: | RHEL - 7 - 6.1810.2.el7.centos OS Description: | oVirt Node 4.3.1 Kernel Version: | 3.10.0 - 957.5.1.el7.x86_64 KVM Version: | 2.12.0 - 18.el7_6.3.1 LIBVIRT Version: | libvirt-4.5.0-10.el7_6.4 VDSM Version: | vdsm-4.30.9-1.el7 SPICE Version: | 0.14.0 - 6.el7_6.1 GlusterFS Version: | glusterfs-5.3-2.el7 CEPH Version: | librbd1-10.2.5-4.el7 Open vSwitch Version: | openvswitch-2.10.1-3.el7 Kernel Features: | PTI: 1, IBRS: 0, RETP: 1 VNC Encryption: | Disabled Is anyone running teamd on this version ? Thanks in advance -- Kind regards / Met vriendelijke groet, Valentin Bajrami Target Holding

botched 3.6 -> 4.0/1/2 upgrade, how to recover
by Axel.Thimm＠01lgc.com 14 May '19

14 May '19

Hello, an old 3.6 self-hosted one-system installation was half upgraded to 4.0 and I took on the task to continue upgrading it. I managed to setup a new engine and upgraded step by step until 4.2 where the host needs to be upgraded. During that time the host was "non-responsive", but I though that this had to do with the upgrade process. Upon trying to upgrade the host the setup broke to pieces. I tried to downgrade everything and restart the old engine to no avail. I now try the way forward to try to start the new engine or create a complete new one, I don;t care much about the old engine's inherited information - all I need to to resurrect the VMs again. At the end of the day the setup is supposed to migrate to a three system hyperconverged setup anyway. How should I proceed to get a working state that fires up the VMs? Is it safe to install a hosted engine from scratch and reattach the domain? Probably the VM configuration will be lost and I will have to puzzle together the disks. I still have the 3.6 engine's backup file, if that is of any help. Should I perhaps recreate a 4.0 engine with that file and try to continue from there? I guess all information on which VMs are attached to which images etc are in the DB of the engine, so I either have to get this info off the 3.6 backup or wire them up again by inspection. BTW this is not a pure ovirt, but an RHV with self-evaluation support, but I believe that any pure ovirt solution will apply. Many thanks in advance.

I'm using teaming and I don't see issues. Just cannot control the teaming device.

A "memory" issue when trying to start VM on oVirt 4.3
by Vrgotic, Marko 14 May '19

14 May '19

Dear oVirt, We are running 4.3.3 oVirt with SHE on three CentOS nodes for HA – with NFS storage. We also have two Local Storage DCs managed by same SHE. [cid:image001.png@01D50A59.F4276FD0] The issue we are reporting was present on 4.3.2 as well. The memory usage on both hosts (third one is in maintenance mode) does not go above 45%: [cid:image002.png@01D50A59.F4276FD0] I have also attached the UI Dashboard screenshot. However, when trying to start one VM: [cid:image003.png@01D50A59.F4276FD0] Engine reports that there is not enough memory and writes the following in the engine.log: 2019-05-14 11:23:10,809Z INFO [org.ovirt.engine.core.bll.RunVmCommand] (default task-14) [63aa9817-80fd-4b18-8c86-26c910a2954a] Lock Acquired to object 'EngineLock:{exclusiveLocks='[13b2299f-b4b4-48e4-b2f9-09450eff235d=VM]', sharedLocks=''}' 2019-05-14 11:23:10,819Z INFO [org.ovirt.engine.core.vdsbroker.IsVmDuringInitiatingVDSCommand] (default task-14) [63aa9817-80fd-4b18-8c86-26c910a2954a] START, IsVmDuringInitiatingVDSCommand( IsVmDuringInitiatingVDSCommandParameters:{vmId='13b2299f-b4b4-48e4-b2f9-09450eff235d'}), log id: 5f80129f 2019-05-14 11:23:10,819Z INFO [org.ovirt.engine.core.vdsbroker.IsVmDuringInitiatingVDSCommand] (default task-14) [63aa9817-80fd-4b18-8c86-26c910a2954a] FINISH, IsVmDuringInitiatingVDSCommand, return: false, log id: 5f80129f 2019-05-14 11:23:10,833Z INFO [org.ovirt.engine.core.bll.scheduling.SchedulingManager] (default task-14) [63aa9817-80fd-4b18-8c86-26c910a2954a] Candidate host 'ovirt-staging-hv-01' ('d81b296a-f3b2-49ea-9b4d-04c90f3508e9') was filtered out by 'VAR__FILTERTYPE__INTERNAL' filter 'Memory' (correlation id: null) 2019-05-14 11:23:10,833Z INFO [org.ovirt.engine.core.bll.scheduling.SchedulingManager] (default task-14) [63aa9817-80fd-4b18-8c86-26c910a2954a] Candidate host 'ovirt-staging-hv-02' ('f4fdeccd-4cf4-4ed7-9eb1-d98ac65c4ce6') was filtered out by 'VAR__FILTERTYPE__INTERNAL' filter 'Memory' (correlation id: null) 2019-05-14 11:23:10,838Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-14) [63aa9817-80fd-4b18-8c86-26c910a2954a] EVENT_ID: USER_FAILED_RUN_VM(54), Failed to run VM csm2-216-d due to a failed validation: [Cannot run VM.

Re: Gluster volume heals and after 5 seconds has /dom_md/ids dirty again
by Strahil 14 May '19

I have just noticed this behaviour. I stopped and redesigned my brick (addded vdo layer) and after the heal (1000+ entries got sync) the dom_ids need healing. Running 'gluster volume heal volume_name full' heals the file and 1 min later it happens again. I will try to do a rolling reboot and see if the issues got fixes.

The heal entries will disappear for a few seconds and then /dom_md/ids will pop up again. The __DIRECT_IO_TEST__ will join later. The split-brain info has no entries. Is this some kind of hidden split brain? Maybe there is data on node01 brick which got not synced to the other two nodes? I can only speculate. Gluster docs say: this should heal. But it doesn't. I have two other volumes. Those are fine. One of them containing 3 VMs that are running. I also tried to shut down the engine, so no-one was using the volume. Then heal. Same effect. Those two files will always show up. But none other.

Gluster volume heals and after 5 seconds has /dom_md/ids dirty again

I restored my engine to a gluster volume named :/engine on a three node hyperconverged oVirt 4.3.3.1 cluster. Before restoring I was checking the status of the volumes. They were clean. No heal entries. All peers connected. gluster volume status looked good. Then I restored. This went well. The engine is up. But the engine gluster volume shows entries on node02 and node03. The engine was installed to node01. I have to deploy the engine to the other two hosts to reach full HA, but I bet maintenance is not possible until the volume is healed.

Re: oVirt Open Source Backup solution?

Another option is to create a snapshot, backup the snapahot and merge the disks (delete the snapshot actually). Sadly that option doesn't work with Databases, as you might inyerrupt a transaction and leave the DB in inconsistent state.

I am having hard time installing OVIrt. Gluster deployment for the single node sometimes work, but host engine deployment never works. Any one has suggestion on which release of OVirt to use as a beginner.
