That sounds great!
It's currently still reindexing - it took ~ 1 hour for the first 4 years, which I think is normal.

Yes, the chainstate is a LevelDB database and just the mempool + some meta date.
I think it should be updated once the reindexing is finished, however, I'm not sure on that... Let's see after it's finished.

I tried the fix described here https://www.reddit.com/r/Bitcoin/comments/3ywfyq/got_error_opening_block_database_in_bitcoinqt/, but this didn't work for me - I was too lazy to troublshoot - thus I decided to scrap the entire chainstate 

Thanks @xdrpx and @aleksej996 for the fast reply! Have a good one!!

Hi,
I've been running a BitcoinCore Client for about a year on my Windows 10 machine and now I want to move it over to my Raspberry Pi 3.
I've followed the great and thorough instructions by http://raspnode.com/diyBitcoin.html and I can start BitcoinCore just fine [both the GUI and the daemon].
However, downloading the entire Blockchain over the Raspberry is pretty much impossible from what I've heard.

I tried copying the blocks and chainstate directory from the Windows Client on the HDD [I know that a SSD is preferable, but I think the HDD works as well] I use for the Raspberry.
Are there any issues copying from a Windows client to a Raspbian client?

When running bitcion-qt with the -datadir tag pointing to the mounted HDD following error shows: Error opening block database.
I've deleted the chainstate directory from the HDD, that resolved the error, but I have to redownload the current chainstate from the Pi, which is not ideal...
Any way I can work around this issue?

So now I only have the blocks directory on the HDD and when I run bitcoin-qt it says it is reindexing blocks on disk. Does this mean that it is only verifying if the available blocks are correct? And once the reindexing is finished, are there any other steps necessary?


I would be delighted to get help - thanks in advance!
And a prosperous new year to all of you!!
