That is good to know. So in theory: - crush move osd to a different server bucket - shutdown osd - move physically to another server - no rebalancing needed Should do the job? It won't accept today's rebalance, but it would be good to have a sane way for the future. Cheers, Nico -- Modern, affordable, Swiss Virtual Machines.
