    Default Had an Error that made me laugh but was serious

    We have a Active/Passive configuration and on Saturday, we had alarms that the replication partner was not reachable. So i click on the console of the primary server and it said "Network card is not accessible do you have some form of power saving enable, I am dazed and confused"

    Ok so the network card had died in the primary server, so i deleted the binding between the servers and created a new bond with spare network cards that where in the servers. Recreated the partnership, recreated replication tasks but they would not start, i cleared the metadata but nothing would work, i even delete and recreated the destination volumes. It just kept saying already part of a replication task. So I built a new server and migrated the data across. What else could I have done to get this working correctly?

    Strange. In up53 we fixed:
    After hosts unbind, DRBD ports are not reset.

    Any chance you have logs from before and after? Compare \drbd\drbd.log2 between versions and machines to see if something is different.

    Just an update, our severs are dell R720 Gen 12 servers I found a document on chanigng bios settings that resolves this issue, basically it changes the server to be better for low latency. We have made the changes and so far all is ok

    Thanks for the update, was the BIOS change related to the power settings?
    All the best,
