Description Simone Tiraboschi 2014-09-17 15:50:03 UTC

Description of problem:

I'm using two host: one for the engine, the other as an hypervisor.
Both with latest fedora 19 updates.
I installed the ovirt engine, release 3.5 RC2, on the first host and from the web admin UI I was trying to add the second host.

First attempt generates errors saying that I have to set cluster compatibility level to 3.3; after that I still wasn't able to add my host.
Trying to add it into my cluster I'm getting:
 Status of host f19t12 was set to NonOperational.
 Gluster command [<UNKNOWN>] failed on server f19t12.
 Gluster command [<UNKNOWN>] failed on server f19t12.
 Host f19t12 does not enforce SELinux.

That host instead enforces SELinux

Version-Release number of selected component (if applicable):
3.5 RC2

How reproducible:
100%

Steps to Reproduce:
1. two fedora 19 hosts, install the engine on one of them
2. Downgrade cluster level to 3.3
3. without adding any additional rpms repository on the second host try to add it via the web admin gui

Actual results:
It shows error about SELinux and Gluster.

Expected results:
It correctly adds the host or at least it fails advising the user to upgrade vdsm stuff to the required release

Comment 1 Dan Kenigsberg 2014-09-17 18:22:28 UTC

Would you provide ovirt-host-deploy.log of failed and successful installation? vdsm.log and engine.log are required too, to understand what was deemed wrong.

I tried to reproduce on a fresh environment and is 100% reproducible.
I have 4 distinct case where it doesn't work and just a working one; I'm attaching the required logs.

It looks like this is a libvirt version implication ?

Danken ? Yaniv ?

Comment 10 Dan Kenigsberg 2014-09-21 20:16:43 UTC

Yes, Barak. The libvirt shipped in F19 is not new enough to support clusterLevel 3.4 or 3.5. If someone wants newer feature, he needs to fetch libvirt from virt-preview or upstream.

There's nothing we can do about it, apart of waiting for F19's obsolescence.
