Wildo / Hemant; Current recommendations (since at least luminous) say that a block.db device should be at least 4% of the block device. For a 6 TB drive, this would be 240 GB, not 60 GB.

That should work in allmost all configurations. 220GB is more then you need for the DB as well. It's doesn't hurt, but it's not needed. For each 6TB drive you need about ~60GB of space for the DB.
