Status of Ethereum Sync using Geth for Beginners

Question

I am new to ethereum and right now getting the ethereum blockchain using geth with syncmode=fast and cache=5120

It's been quite some time the sync being running (about 24 hours) and still the process has not completed.

I was wondering what the current status is looking at the log, but I am not able to understand much.

Can anyone tell me what the below details signifies? What does each parameter states? Till which block has this synced and other relevant details?

Any help is appreciated!

Answer 1

As long as you see in the logs INFO [xx-xx|xx:xx:xx] Imported new state entries .... the network is syncing.

You can check progress with command eth.syncing(from the geth console), if syncing is on going you must see:

{                         
  "currentBlock": xxxxxxx,  
  "highestBlock": xxxxxxx,  
  "knownStates": xxxxxxx,   
  "pulledStates": xxxxxxx,  
  "startingBlock": xxxxxxx  
} 

When process is complete you'll see INFO [xx-xx|xx:xx:xx] Imported new chain segment ... entries in the log.

Answer 2

It looks you have sync problems slow syncing etc, the easiest way to recover from this slowdown is to remove your blockchain data and restart Ethereum Wallet. Ethereum Wallet will then perform a fast sync which skips over these attack blocks.

WARNING: Make sure you back up your keystore directory so you don't accidentally delete your account information.

Shut down Ethereum Wallet.

Depending on your operating system, you will find the chaindata subdirectory in:

Linux - $HOME/.ethereum/geth
OS/X - $HOME/Library/Ethereum or $HOME/Library/Ethereum/geth
Windows - %APPDATA%/Ethereum

Remove the chaindata directory.

Alternatively, you can run geth removedb to remove the blockchain data.

Start Ethereum Wallet. It should now start fast syncing the blockchain data. Alternatively, run

geth --syncmode "fast" --cache 1024 console 

and then start Ethereum Wallet.

This works for me.
