Hi all, I am attempting to prevent bluestore rocksdb Level 3/4 spillover with a 150GB logical volume for the db/wal. I am thinking of setting max_bytes_for_level_base to about 1.3G (1342177280). This should let Level 3 fill up the 150GB logical volume. I don't expect to ever actually need L4. Another option would be to set max_bytes_for_level_base to 128m. This db/wal device is a fast SSD. OSD is HDD. Any opinions on whether it would be better to increase max_bytes_for_level_base to over 1G or decrease it to 128m? thanks, Frank
