Answer 1

in your migrations you have to specify the gas amount

Answer 2

You're probably overlooking the need to unlock and fund the account you're deploying from.

Have a look over here: truffle deploy: Network state unknown when geth is synced

Hope it helps.

Answer 3

See Ankush answer: https://ethereum.stackexchange.com/a/6310/44800

with command eth.getBlock("latest") you get your gas limit maximum. I have similar problem, and with this info it works when I set my gas (limit) for this maximum. At my case it was 5000000 (higher than truffle default 4712388)

Another way is to reset node gas limit: see: How to increase gas limit in block using geth?

Answer 4

This might be the indication of some mistake in a smart contract that you are trying to deploy. Can you share a code of smart contract that you are trying to deploy? You might need to debug the code line by line to understand the cause of this exception.
