[ceph-users] adding block.db to OSD

Hello, is there anything else needed beside running: ceph-bluestore-tool --path /var/lib/ceph/osd/ceph-${OSD} bluefs-bdev-new-db --dev-target /dev/vgroup/lvdb-1 I did so some weeks ago and currently i'm seeing that all osds originally deployed with --block-db show 10-20% I/O waits while all those got converted using ceph-bluestore-tool show 80-100% I/O waits. Also is there some tuning available to use more of the SSD? The SSD (block-db) is only saturated at 0-2%. Greets, Stefan
