How to remove the previous BlockChain data?

I am learning to develop chaincode and when testing it, when i killed the peer and restarted the blockchain, the blockchain did not start. I thought this could be because there already exists data about previous blockchain. Am i right? How to remove blockchain data?

One of the reasons preventing the blockchain to restart could be the previous blockchain data. The blockchain data is stored in the /var/hyperledger/production/db folder. Delete the file and try restarting the blockchain.
