  1. Web interface not working, and /etc/pve not mounting

    Hi, We have a cluster of 9 nodes with a ceph pool for vm storage, lately we stopped to have access to the web UI, but we still have ssh access to the servers, and all the VMs are still running fine. We've tried to debug the problem with no luck, the only thing that we were sure about is that...
  2. [SOLVED] node disconnect from cluster when in vlan

    Hi, When I put the ip of the node directly in the physical interface or in the vmbrX everything works fine, but when I pass this ip to vmbr.100 (see below) I lose the connection with the other nodes in the cluster and when I restart the node (despite the web interface loading ) I can't log into...

  4. One way only replication.

  6. Found a bug with using IPv6-based clustering; also a hostname error

    Hey all. There seems to be two bugs regarding clustering setup and IPv6 addresses... 1. If you decide to use custom fe80:: addresses on a vlan/other interface, it may default to the primary network interface regardless (i.e. vmbr0 vs vlan###). 2. If you use a routed address, and it has a :: in...
