The error with peer banning is happening because a block that it read is probably corrupted and that block is marked as invalid. Then Bitcoin Core will try to continue to sync from its peers, but those peers are sending it the block that it had marked invalid so it will ban those peers. Eventually it will ban everyone it could get a connection to. To fix the peers banning problem, stop Bitcoin Core, delete the file named peers.dat, and start Bitcoin Core again.

I suspect that you have a hard drive failure. You have experienced what appears to be two cases of corrupt blocks on your hard drive. I suggest that you run hardware diagnostics to see if it finds anything wrong with your hard drive. You should stop running Bitcoin Core for now as it won't be doing anything if it can't sync the blockchain.

It could be faulty RAM too. I had my blockchain files to corrupt often before I realized that one of the RAM slots had errors (not the actual RAM stick in my case, but the actual slot in the motherboard caused some ram sticks to show up errors on Memtest). So I recommend op to run Memtest in a live CD to discard ram stick/slot problems too.
It's going to be a pretty slow process tho, he has 32GB.. I only got 8.. but I imagine with his stronger computer he will test faster, my CPU is from 2008 :p

No idea why. I changed nothing I had not changed before. Bitcoin Core just work this time. Quick and without error.

The Armory doesn't start normal, but I can start off line. I've pointed it to the core and it does nothing. So there will be some gymnastics to get it's wallet read and funds ready to move.

I just haven't had time since I've only a month or so left till the Phx heat kicks in. I'll work on it then. I did get my Frankin Miner going that putts out Ethereum at 50Mhz and only 250W. It's now in the shop ready for the heat test.

Is this sorted now?

Have you any idea what may have caused the problem with the earlier downloads?

It sync'd and now I'm coping in to my NAS just in case the Armory reset blows it up.. Then it's time to choose a plan of action with my balance.

Yep, my 66Tbird only seats two kind of comfortable. It's like an airplane cockpit inside. Heavy car that doesn't act like a car till 90mph. Then it floats like dream stops like a ocean liner. It's 460 is setup modern for 600hp with stupid amounts of torque so if you don't know any better it's a blast to drive. I've found god in it enough times that it scares me now. I've just made up my mind I'm going to sell it. None of my family would give it the respect it needs to keep them alive. A GTO would be better. Those GM A bodies were great. I loved my Cutlass.

Why would it work this time so smoothly and not the other half dozen times I've tried since December?

Could be a number of things, but if it was always hanging at around the same place, it sounds as if it's a disk error.

Glad it looks as if it's working anyway.

Only room for 2 in that T'bird - I could turn it into a camper van.

I nearly bought a softtop Pontiac GTO when I was in California. I wish I had, as they have shot up in value, but it would have cost too much to get it back to England.

It's 96% and moving strong. I mean it's counting them right down at a consistent pace. Going up on the 99% stop and wait point.

BTW, only room for two to party in the 66 Tbird. I could buy a tank of gas and some Sonic food with the .05btc at this rate. The car is so expensive to drive a 8 mpg and I live were kids will key a nice car just because. It stays in storage till I find an heir that will care for it proper.

You know - we expect to party in the T'bird when your node is sync'd and working.

Still roll along at 58% and 68Gb download, or so it says.

I still feel that if you have the disk space, and you can go online to sync' your blockchain at least once every two or three days, that you are better off running a core node. It gives you more flexibility and control. Using an online wallet is effectively the same as using a fiat bank, and Bitcoin was designed to escape from their controls.

What are my options to easily convert my btc into eth? Doing the p2p thing just isn't something I'm having faith in.

Honestly, just export your private keys from Armory... you don't even need Bitcoin Core installed, let alone synced, to be able to do this

- Wallet Properties
- Backup This Wallet
- See other backup options
- Select "Export Key Lists" option (top left)
- Click "Export Key Lists" button (bottom)
- Select the following: "Address String", "Private Key (Plain Base58)", "Include Unused (Address Pool)" and "Omit spaces in key data"

All your addresses and private keys will be displayed in the text box. You can then copy/paste or save as required.

Then you can either import/sweep into a lightweight wallet like Electrum (https://electrum.org/#download) and convert to ETH by depositing on an exchange or using changelly or whatever (note: fees will apply)

Usual disclaimer about being careful with private keys applies

That's good to know. Just start Armory offline is what I was told previously. I'll give that a try tomorrow.

The restart of the core download 24 hours is still moving along at 42% which has slowed but way head of previous attemps.

No, thank you for letting us share your pain.

It's actually a really interesting thread for me. Especially as I am looking at ways to reduce my synchronisation time, and I'm about to decide on the upgrade of my notebook machine.

Thank you for the replies. I'm going to digest it a while.

Out of desperation, or just plain ignorance I deleted the last three block files because they were smaller that the typical. Then deleted the peers. Hit the -reindex batch file (I've done this enough to make one) and this morning it's at 30%. That's twice the rate it has been progressing and more like the way it did years ago.

This time if or when it fails I'll have a full debug file to show.

Thank you for not giving up on me.

I understand the sequence in a standard core download. You install the core software, and then either you give it an empty directory for the blockchain, or you give it a preloaded directory for it to check and synchronise. Once it has done that, does it create the wallet, or is that done in the initial core installation?

If the directory does not contain anything named wallet.dat, the client will automatically create the wallet file at start up.

Quote from: Jet Cash on March 28, 2018, 05:06:58 AM

If you have downloaded 99% of the blockchain, would it not be possible to copy the created directory onto an external SSD ( or an SD card), and take it to another computer to install a new version of core, and give it the copied blockchain to see how it handles it?

If it has downloaded 99%, and then is failing each time, then the fault must lie in whatever operations core does when it completes the download. Were it to be a faulty block, then the additions to the blockchain between downloads would reduce the percentage.

It's possible and thats essentially what the OP is doing now. If anything, I would suspect that the SSD has some issues with it and its not with the computer or the synchronization itself.

At what stage do you give it an Armory wallet? Can you perform a standard installation, and add the armory wallet afterwards?

Yes. Armory just needs the data from Bitcoin Core to run. As long as you can point armory to the synchronized blockchain, it would take a few minutes to read the blockchain and create its own database.

I'm quite interested in this problem, and I would be grateful if someone could run through the sequence of events. I've never used an armory wallet.

No peers, no traffic, no cpu usage, nothing, Been a few days now.

All the computer tests show good. SSD is and has been error free. ( It's solid, lol)

You may have another problem with your computer if you're getting corrupted blocks and get blocked by others. There is a reason to this.

Quote from: 66tbird on March 27, 2018, 09:46:40 PM

I'm at a loss. I'm tired of researching. I've tried everything I've read to save the blockchain I've downloaded at least twice. Amory is dead too (as in no traffic, no cpu usage, nothing). I've reloaded the system clean once and after ten days the second download also hung at 99%. I started this wallet recovery in December.

If Bitcoin Core is able to read your wallet, you've access to your private key(s). Export these keys using Debug Console (dumpprivkey - A private key in wallet format starts by 5 or L or K, depending the public key is compressed or not) and use Electrum as suggested to sweep coins from your old address by one managed by Electrum (Wallet/Private Key/Sweep). Electrum is able to run without download the whole chain, using API calls to remote nodes.

You can also use a online wallet allowing to import private keys.

Did you delete the faulty blocks?

Here is my past cropping up again - have you checked the cable connections for the hard drive? Make sure there isn't any magnetic interference around as well. I'm clutching at straws, but you never know.

Thank you for the advice. I've done the peers delete and I've got peers again but they quickly vanish. Nothing much else is moving.

Ran the tests on my SSD (Samsung 950 pro 1Gb) and it's had no errors.

P2P the file maybe the answer
