    hi,

    i have 3 identical servers with integrated dual 10g sfp+ eth and dual 1g eth
    [Supermicro X10SDV-2C-TP8F]
    - the 1g nics are connected to redundant switches (frontend)
    - the 10g nics are connected direct (backend ceph)
    I tryed the configuration, shown in the video, but after restarting the nodes the network is broken
    [https://www.proxmox.com/de/training/video-tutorials/item/install-ceph-server-on-proxmox-ve]
    Just doing the steps [01:30 - 02:35], bonding only the 2 10g nics and restart the node results to the same problem.
    And even just setting up a static ip on one 10g nic cuts back all others nics on that server.
    As a result no incomming or outgoing connections on any nic are possible.
    ---
    Installation with the 5.2.1 iso and successfully updated via apt-get update && apt-get dist-upgrade
    I found out, that the ixgbe driver [5.1.0-k] is a little older than the igb [5.3.5.18] version, but i'm not experienced enough to compile it into the kernel. (error: code model kernel does not support PIC mode)
    Using ’ixgbe allow_unsupported_sfp=1’ or ’ixgbe allow_unsupported_sfp=1,1’ doesn't fix the problem, too.

    problem solved, after using a different subnet for 10g.
