I am running Windows Seven Enterprise: wondering if someone can advise me on the following. I had Ethereum Wallet on C:\ with only 12 GB free. I moved the Ethereum folder to E:\ and tried to setup the blockchaindir on E:\Ethereum Wallet using geth.exe --fast --cache=1024 datadir=E:\Etherdata

The proces starts downloading and shows the following error/warning: enter image description here but seems to continue happily

and then quits / hard stop after like 2 minutes without any clear warning at the following screen: enter image description here

Any advice is greatly appreciated, thanks!

Cant you just create a link and point your windows directory to the one in E drive

Steps

  • Believe by default Ethereum directory is present here C:\Users...\AppData\Roaming\Ethereum
  • Rename the C drive Ethereum directory to something else lets say Ethereum-Backup

  • Open the command prompt in admin mode

  • cd C:\Users...\AppData\Roaming

  • mklink /D Ethereum E:\Ethereum

  • Start geth client

  • If everything works fine you can take the decision to remove the Ethereum-Backup directory

Second Part

You can check the size of which chaindata folder as listed below is getting updated or not. You can check the latest file modified date. I believe you might be in the main network (i.e. homestead) due to which it is taking long time to sync.

Also check which folder size is increasing.

Main Network Data Folder C:\Users...\AppData\Roaming\Ethereum\geth\chaindata

Test Network Data Folder C:\Users...\AppData\Roaming\Ethereum\testnet\geth\chaindata

You can always start the getch client with a new genesis config file

geth init genesis.json

By the way if your intention is to practice Ethereum then you can use Testrpc. Testrpc basically simulates Ethereum block chain. You don't have to wait long for your deployments or synching issues. In addition Parity has developed a new testnet named Kovan which in similar lines much stable and good for developers.

  • Thank you @Susmit. I am trying this now as we speak , created the symbolic link, that seemed to work, Geth is running now too, does it matter when I fire up Ethereum Wallet at this point? Thanks!! PS: What I dont get, i just fired up Ethereum wallet in parallel with Geth still synching/running, and it still seems that Ethereum wallet is starting a separate synch process....am I missing something here? – EthereumNoob Mar 18 '17 at 23:01
  • Glad it helped. Is it possible that mist is hitting main network and direct instance of geth hitting testnet? Secondly have you confirmed from your task manager that you have two instances of geth running when you start mist? – Susmit Mar 19 '17 at 4:25
  • Checked Taskmanager: Geth only seems to be running once (btw, since I started it, it still running hasnt stopped yet). I dont know how to tell if Mist is htting main and direct geth is hitting test (sure dont hope so, its been running for 18 hours or so now) – EthereumNoob Mar 19 '17 at 17:27
  • Folder seems to be filled with 13 GB only so far...(does this mean it will run until the 90GB is completed? ) and how will the Ethereum Wallet know where to look for the data? – EthereumNoob Mar 19 '17 at 17:41
  • So that does mean that only single instance of geth is running and mist has not started a new geth instance. What is the command you used to start geth. Did you apply --testnet as that is used to run the Ropsten testnet. In Mist app under Develop->Network menu you can see what network is selected. Also next to the Send menu it should list the network name on which it is running. In testnet I think it should be at max 16 or 17 GB of data. – Susmit Mar 19 '17 at 18:03
