I have 1 480GB SSD and 7 2TB HDDs. 7 LVs are created on SSD, each is about 64GB, for 7 OSDs. Since it's shared by DB and WAL, DB will take 30GB and WAL will take the rest 34GB. Is that correct? Is that size of DB and WAL good for 2TB HDD (block store and object store cases)? Could you share a bit more about the intention of such limit? Thanks!
