Geth miner not working

Question

I have created a private network and created accounts. I have made a transaction and now trying to mine the transaction. But when I try to mine, mining is not happening. It shows null:

> miner.start()
null

Answer 1

Hi. miner.start() gives no output. So, when the output is null, it does not mean that mining is not happening. To check if mining is happening or not, you can read the logs:

$ geth --datadir ./path/to.datadir --networkid <network id> console 2>> Eth.log

And then in new terminal run this

$ tail -f Eth.log
