[lalit patadiya]

I am trying to install bitcored on my server and it'll install and working f9 with testnet, now I want to  move server with livenet for that one I have made changes all the required changes and execute the below command

> bitcored

and it'll start sync but after 91%, meanwhile somehow my internet connection is gone and the process stopped, also I have to restart my system again try to resume the process at that time it'll giving an error like below :

[2018-06-15T08:37:21.554Z] info: Starting bitcoin process

Do you want to rebuild the block database now?

It seems you files are somehow corrupted.
Did you actually try to rebuild the database? Or did you just hit CTRL+C to cancel each time?

[lalit patadiya]

Yes i have rebuild the database using -reindex=1 then it'll start the process again from 0.0 to 84% then stop the process with the same error

You may have to resync the blockchain.
-reindex wipes the chainstate and block index and rebuilds them.

But it seems like you have corrupt block files. The best option probably would be to sync from scratch.

Did you check wether your hardware does work as intended? Do you have the blockchain stored on an external hard drive (those are more error-prone) ?

[lalit patadiya]

Actually, I have store my all the data on my GoDaddy server, if I am starting again from scratch then it'll take again 8-9 days for 100% sync

[bob123]

Did you already try to delete the latest few downloaded block files and run --reindex afterwards? It may be worth a try.
They are usually located in ~/.bitcoin/blocks/ (linux) or %APPDATA%\Bitcoin\blocks (windows).

[lalit patadiya]

But I think --reindex will start from scratch right?

[bob123]

--reindex will wipe and rebuild the chainstate and block index.
It does not repair broken block files. You will need to resync and redownload those corrupted block files.

--reindex just reads the files you already have stored on the disk. It will only download blocks that it does not already have.

You will need to manually remove the corrupted block files to force it to redownload them.

Does any one has idea ?

bitcore ( https://thebitcoincore.org/ ) is not bitcoin

[lalit patadiya]

"You will need to manually remove the corrupted block files to force it to redownload them."

I did but it's not working it'll give the same error again.

I did but it's not working it'll give the same error again.

If you are certain that you removed the correct block, an idea would be to look into your antivirus logs, maybe it "disinfected" something in that file (?).

Does your VPS (hosting) plan comes with an unlimited bandwidth and storage space?
I don't know how big the current <Bitcored?>'s node is, so the problem might be the current size of your node on GoDaddy's server.
Or it may be non-compliant to their terms and conditions and they set a cap on your storage space.

We don't limit the amount of storage and bandwidth your site can use as long as it complies with our Hosting Agreement. Should your website bandwidth or storage usage present a risk to the stability, performance or uptime of our servers, we will notify you via email and you may be required to upgrade to a Virtual Private Server or Dedicated (Private) Server, or we may restrict the resources your website is using.
