Description of problem: add 3.2 vdsm to 3.3 engine to DC with 3.3 compatibility mode. the host becane non operational. remove button was disabled. Maintanece buttom was enabled. I pressed to put host into maintenance it stayed in preparing for maintenance and didn't move to maintence state. Version-Release number of selected component (if applicable): rhevm-3.3.0-0.33.beta1.el6ev.noarch
I was unable to reproduce this on oVirt master and RHEVM is23.1. Here are steps: 1) Create 3.3 DC and Cluster 2) Add 3.3 host (vdsm from is23.1) 3) Setup NFS storage on DC 4) Everything is OK 5) Add 3.2 host (vdsm from sf21.1) 6) After installation 3.2 host became NonResponsive 7) Move 3.2 host to Maintenance -> host successfully moved to Maintenance
