Comment 1 Barak 2015-06-09 08:51:24 EDT

Should we also remove 3.2, 3.1 & 3.0 from the clusterLevels supported ?

> Should we also remove 3.2, 3.1 & 3.0 from the clusterLevels supported ?

Yes.  Remove these.  EL 7 Hosts are only officially supported on cluster level 3.5 and in Tech Preview on 3.4.

Comment 6 Oved Ourfali 2015-06-11 10:37:35 EDT

Based on discussion offline, and comments in the bug, we will do the following in VDSM in EL7:
1. Remove clusterLevels 3.0-3.3
2. set supportedEngines to 3.4 (due to tech-preview) and above.

Comment 8 Max Kovgan 2015-06-28 10:12:27 EDT

ovirt-3.6.0-3 release

Comment 9 Petr Kubica 2015-07-29 10:41:17 EDT

Hi, I tested adding 3.6.0-4 host to engine 3.4.4-1 and it's not working: "installation failed. Network error during communication with the host."
Should it works ?

but when I try add the host to 3.5.3.1-1 engine with cluster compatibility level 3.4 it works.  

I found only this error:
/var/log/messages
journal: vdsm ProtocolDetector.SSLHandshakeDispatcher ERROR Error during handshake: unexpected eof

/var/log/vdsm/vdsm.log:

Comment 10 Yaniv Bronhaim 2015-08-10 13:09:47 EDT

I suggest to open a separate bug on that issue which describes the vdsm and engine versions, os type, the flow you tried to run and contain related log

Comment 11 Petr Kubica 2015-08-31 04:05:11 EDT

Verified in vdsm-4.17.0-1239.git6575e3f.el7.noarch
