Moving the blocks

[flyup]

I'm creating a new bitcoin-qt installation on a Linux Mint/ubuntu virtual machine.

I've tried moving the blocks folder over without success

Code:

bitcoin-qt -reindex 

will begin reindexing on the disk and then it fails around week 40

What am I doing wrong?

This is the failure:

Code:

bitcoin-qt -reindex
bitcoin-qt: main.cpp:1761: bool ConnectBlock(CBlock&, CValidationState&, CBlockIndex*, CCoinsViewCache&, bool): Assertion `hashPrevBlock == view.GetBestBlock()' failed.
Aborted

Which Bitcoin Core version are you using?

[flyup]

core version 9.3.0

I've tried re-indexing with and without a network connection.

I've tried moving over the chainstate folder

I've tried moving every file/folder over except wallet.dat

Reindexing still fails -

I've tried it now on 9.4.0 too.

Why am I having such difficulty moving the blockchain?

It seems like I did this a few months ago without an issue.

It does seem odd you are having the problem because (as you noted) it is possible.

You might just trying running 0.10.0rc3 and re-download the blockchain.  It will in all likelihood be much faster than banging your head against the wall on this more.  ;-)

hehe right. this would be much easier.

Did you also move the chainstate folder?

He said he tried 0.9.4 (this version came out for Ubuntu only at the moment and coming soon for Windows) , Basically 0.10.0rc3 = 0.9.4 the Final release . so I don't think it will change anything .
Delete all the downloaded blocks & Try downloading the torrent Bootstrap file and place it on the Bitcoin Data Directory and run your wallet again . It should Import from the disk just fine and probably start synchrozning with the network if some blocks missing .

[...]Basically 0.10.0rc3 = 0.9.4 the Final release[...]

This is not correct. 0.9.4 fixed an issue with OpenSSL which affected mainly the Ubuntu PPA. https://github.com/bitcoin/bitcoin/blob/41f94edf221019a6c4b8f78c2b17c389442f546e/doc/release-notes.md

0.10.0RC3 introduces more features i.e. "headers first". Preliminary release notes: https://github.com/bitcoin/bitcoin/blob/0.10/doc/release-notes.md

Additionally RC stands for Release candidate, so it's not a final release.

I'm beginning to think I've encountered a bug in XFCE or core version 9.4.0 and 9.3.0

I've tried moving the blocks [blocks folder] - returns:

Code:

bitcoin-qt -reindex
bitcoin-qt: main.cpp:1761: bool ConnectBlock(CBlock&, CValidationState&, CBlockIndex*, CCoinsViewCache&, bool): Assertion `hashPrevBlock == view.GetBestBlock()' failed.
Aborted

I've tried initializing with bootstrap.dat

This imports blocks from disk- then after a rescan the core fails with no error message.

Any ideas?

[flyup]

I was successfully able to move the blocks to a Windows 10 Tech Preview virtual machine.

I tried on several different Debian and Ubuntu distros and all my attempts failed.

Hello- Cortana. How much bitcoin is in my wallet?
