If you really are using NVMe for WAL, but not BlockDB, you are shooting yourself in the foot. Ceph will have created a small filesystem for a RocksDB holding metadata- so you are writing to raw disk, then seeking for a write space on FS, then back to raw, then back to write metadata, etc etc.

BlueFS and RocksDB BlueStore achieves its first goal,fast metadata operations, by storing metadata in RocksDB. BlueStore achieves its second goal of no consistency overhead with two changes. First, it writes data directly to raw disk, resulting in one cache flush [10] for data write, as opposed to WebRed Hat recommends that the RocksDB logical volume be no less than 4% of the block size with object, file and mixed workloads. Red Hat supports 1% of the BlueStore block size with RocksDB and OpenStack block workloads. For example, if the block size is 1 TB for an object workload, then at a minimum, create a 40 GB RocksDB logical volume. piosenki nuty litery
