I have run geth --fast --cache=1024 for a week and I think I am almost complete: etherscan.io shows:

LAST BLOCK 4005552

and my eth.syncing shows:

{
  currentBlock: 4005449,
  highestBlock: 4005553,
  knownStates: 1157252,
  pulledStates: 1141319,
  startingBlock: 4005266
}

But geth --fast never change to normal and keep on getting new state only:

INFO [07-11|09:20:49] Imported new state entries count=3 flushed=4 elapsed=0s processed=1273621 pending=10500 retry=2 duplicate=1200 unexpected=2461

What should I do? Can I just stop and run normal geth without --fast flag? Or can I try mining already?

  • To my understanding the fast flag only counts when you start syncing. Once there's data in the geth folder the flag is ignored.

  • In my understanding, as long as it does not download any block (which --fast do) then it can continue to download in fast mode, but after a block is downloaded it will be disabled. The docs said that after geth --fast download the header near the highest block then it will change to normal geth and start downloading block normally (disabled fast automatically). This event is the one that never happened with mine

I wrote a tiny python script to overview the process. It's here https://github.com/hayorov/ethereum-sync-mertics

My output:

I had exactly such problem and finally found that source of problem is my system time! I simply solved the problem with enabling network time synchronization on my ubuntu with following command, and then restarting geth.

timedatectl set-ntp true
