i reinstall the whole cluster. i broken the cluster this way:
1. create cluster on "server a" with one node "server a"
2. delnode "server a" from cluster (i know this is strage - but i just try it if it is possible - it is possible)
-> remove worked - at the fist look
-> pvecm n shows "server a" - it is not removed correctly
3. addnode "server b" to the cluster
-> pvecm n shows only "server b" in the list ("server a" entry is disappeard)
4. try to add "server a" again to the cluster - dont work!
i just playing with the new cluster feature. after this "misconfiguration" i create the cluster the right way and it works well - but i must create a link for /etc/vz/conf to /etc/pve/nodes/xxx/openvz/ manual. openvz ct are running well - but the memory usage is a bit crazy - i know full openvz support is not ready atm - but here the screenshot. if you need the confs, just post a comment - else the thread is closed.
