Unable to change cluster compatibility version
by Logan Kuhn 08 Nov '17

08 Nov '17

Hi We've recently upgraded from 4.0.6.3 to 4.1.6 and we've upgraded all of our clusters except one to 4.1 without issue. The one we are having trouble with is the big important one (of course). The error we get in the interface is: Error while executing action: Cannot change cluster version since following VMs are previewing snapshots: mail-archive1 The log error is a little verbose seeming, so it's attached. I'm not really sure what it means or how to fix it.... Logan

Messed up upgrade to 4.2. Solution badly needed.
by Marcin Jessa 08 Nov '17

08 Nov '17

Hi guys. I have VM with hosted engine and a two node setup. When beta came out I was “OH! New shiny tech! Let’s try it!”. You all know the feeling. Unfortunately the upgrade process did not go as expected. I created a backup of my 4.1 installation and started to upgrade the VM. All went well. I then migrated all the running VMs to my second node put the cluster in global maintenance mode and updated one of the nodes. Then I run hosted-engine —upgrade-appliance on the node but it fails: [ ERROR ] Failed to execute stage 'Environment customization': exceptions must be old-style classes or derived from BaseException, not str The log file says: 2017-11-03 13:12:48,259+0100 DEBUG otopi.context context._executeMethod:143 method exception Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/otopi/context.py", line 133, in _executeMethod method['method']() File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/gr-he-upgradeappliance/engine/misc.py", line 180, in _check_spm 'Unable to find this host in the engine, ' TypeError: exceptions must be old-style classes or derived from BaseException, not str 2017-11-03 13:12:48,259+0100 ERROR otopi.context context._executeMethod:152 Failed to execute stage 'Environment customization': exceptions must be old-style classes or derived from BaseException, not str 2017-11-03 13:12:48,260+0100 DEBUG otopi.context context.dumpEnvironment:821 ENVIRONMENT DUMP - BEGIN 2017-11-03 13:12:48,260+0100 DEBUG otopi.context context.dumpEnvironment:831 ENV BASE/error=bool:'True' 2017-11-03 13:12:48,260+0100 DEBUG otopi.context context.dumpEnvironment:831 ENV BASE/exceptionInfo=list:'[(<type 'exceptions.TypeError'>, TypeError('exceptions must be old-style classes or derived from BaseException, not str',), <traceback object at 0x41d8128>)]' 2017-11-03 13:12:48,261+0100 DEBUG otopi.context context.dumpEnvironment:835 ENVIRONMENT DUMP - END I can login to the hosted engine but the nodes are down, the VMs are down and the storage is not connected. Can you please advice what to do now? Is there a way to upgrade my setup? Should I disconnect my second node, which is also upgraded to 4.2 now and try to install hosted engine from scratch? Anything else I can do to save my VMs? Cheers Marcin.

ovirtmgmt network

This is a multi-part message in MIME format. --------------4ED07EBEEF5FDCFA459DA49E Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Hi, I have a question about ovirtmgmt network. When deploying Hosted-Engine it creates ovirtmgmt bridge on top of main nic of the host. This means the HE will be connected to the same network as the main Host connection. Is it possible to separate those subnet, let say I would have something like Host: IP: 10.0.a.b (VLAN a untagged) The host has an IP address on that interface GW: 10.0.a.gw Then i would have a tagged VLAN on top of that interface : IF2 : 10.0.c.x (VLAN c tagged) The host has no IP address on that interface GW: 10.0.c.gw Would it be possible to have the HE connected on IF2, if Yes how do we deploy such a setup?

Advise needed: building cheap HA oVirt cluster with just 2 physical servers
by Artem Tambovskiy 08 Nov '17

08 Nov '17

Looking for a design advise on oVirt provisioning. I'm running a PoC lab on single bare-metal host (suddenly it was setup with just Local Storage domain) and no I'd like to rebuild the setup by making a cluster of 2 physical servers, no external storage array available. That are the options here? is there any options to build cheap HA cluster with just 2 servers? Thanks in advance! Artem

Use [7] for more details on how to enable it. This release is available now for: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later This release supports Hypervisor Hosts running: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later * oVirt Node 4.1 See the release notes draft [3] for installation / upgrade instructions and a list of new features and bugs fixed.

New post on ovirt.org: Setting up multiple networks is going to be much faster in oVirt 4.2
by John Marks 07 Nov '17

07 Nov '17

Hello! Just a quick heads up that there is a new post on the oVirt blog: Setting up multiple networks is going to be much faster in oVirt 4.2 <https://ovirt.org/blog/2017/11/setting-up-multiple-networks-is-going-to-be-…> In a nutshell: In oVirt 4.2 setting up networks is going to be much faster, and consequently, more networks can be set up before the Engine's VDS timeout. Read the blog post. <https://ovirt.org/blog/2017/11/setting-up-multiple-networks-is-going-to-be-…> See you on the oVirt blog!
