  11. (Only) Windows bad diskperformance on PVE 5/Ceph Bluestore

    I am running a PVE 5-Cluster with Ceph bluestore OSDs. They are only HDD OSDs and connected over 2x1GBit bonds. Don't get me wrong here, it isn't productive yet and I don't expect any fancy performance out of this setup. I am highly impressed with the performance of it under Linux-KVMs and when...
