Hi Paul,

The 'reinstall' will attempt to install the latest version of vdsm, it will enroll certificates for the host and more, but if the host was already installed in the system, it will not attempt to re-configure the network.

In your case, there seems to be a mismatch between the repositories (of yum) configured on the host to the cluster level.

In order to support the host within 3.6 cluster, the host should have the 3.6 repo configured (http://resources.ovirt.org/pub/yum-repo/)

Then 'reinstall' will update the latest version of 'vdsm' and will configure it.

Regards,

Moti

Hi,

can anyone explain what this button does?   I have looked in the documentation but have found no reference to it.    Will reinstall only install packages and setting for the host, and leave cluster/storage/networks alone?

I have a cluster version 3.6.2 that will not Activate the host because the message "Host .. is compatible with versions (3.0,3.1,3.2,3.3,3.4,3.5) and cannot join Cluster...".   The host was part of a 3.5 cluster until the upgrade to 3.6.2.

Thanks a million,

Paul
