Hello,
We have the following problem and I have no more ideas what could be wrong
. I can no longer reach two of our three hosts in a small cluster at Hetzner via IPv6. In my opinion, everything is set up correctly and it has already worked as it is set up. We have split up a larger cluster, kept two hosts and added another server, the new server is also accessible via IPv6. All of this actually worked until it stopped working...
What could I have missed?
The Hosts:
Hyperion (old)
Mimas (old)
Dione (new)
Facts:
3 Nodes, Proxmox 8.2.2
IPv4 (192.168.100.0/24) Cluster Network via vswitch
we removed seperate nics on the old nodes which we used as a ceph network
- ssh works fine from all nodes to all nodes
- I already renewed all ssh keys
- The web interface shows a ‘Connection error - Timeout’ when I want to edit Dione from Hyperion or Mimas.
- It is possible to edit Hyperion and Mimas from Dione web ui.
- IP forwarding s enabled
- I can't ping the old hosts
- same config does work on Dione
IPv6 is enabled
/etc/network/interfaces
