Hi, our Ceph 14.2.3 cluster so far runs smooth with replicated and EC pools, but since a couple of days one of the dedicated replication nodes consumes up to 99% swap and stays at that level. The other two replicated nodes use +- 50 - 60% of swap. All the 24 NVMe OSDs per node are BlueStore with default settings, 128GB RAM. The vm.swappiness is set to 10. Do you have any suggestions how to handle/reduce the swap usage? Thanks for feedback and regards . Götz
