Hi, I am playing with Ceph Luminous and getting confused information around usage of WalDB vs RocksDB.
I have 2TB NVMe drive which I want to use for Wal/Rocks DB and have 5 2TB SSD's for OSD. I am planning to create 5 30GB partitions for RocksDB on NVMe drive, do I need to create partitions of WalDB also on NVMe drive or does RocksDB does same work as WalDB plus having metadata on it? So my question is do I really need to use WalDB along with RocksDB or having RocksDB only is fine? Thanks, Pardhiv K
