Hi.
I'm facing a strange problem whith a 2 node cluster. I was working on a host (setting a password for vnc), when i suddenly lost connection to web ui. After this i cannot auth on node 2 of the cluster (web ui). If i do ssh node2 i can login using that credentials. I observed that i if i login on node1 (ssh) i can do ssh on node2 whithout passwd, but when i try from node2 to node1 is saying WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!. So i think sync is broken..
What should i do. The servers are in production.

Ok i have some updates.
I removed the offending key from known_hosts, and i could login between nodes. From web interface on node2 i still couldn't login.
From node1 i observed that when i clicked on node 2 it said cannot connect to localhost on port 85. Looking on node2 I saw that pvedaemon was stoped. After i restarted pvedaemon everything started working. I could login on node1 or node2 and it looks ok, but in syslog on node2 I see this:
Jan 18 22:57:20 pmx2 pmxcfs[265135]: [status] crit: cpg_send_message failed: 9
I previously restarted cman and pve-cluster.
How could i fix this?
Tx.

You usually see hat only a few times when pve-cluster runs before cman starts.

Yes you were right. I restarted pve-cluster and the errors message stopped showing.

Thank you for your help.

Ps. Is there a order in which we should restart services? cman, pve-cluster, pve-daemon... ?
