"Error opening block database. Do you want to rebuild the block database now?"

[P_Shep]

Also tried coping the entire blockchain etc from another machine with 8.1 on it... same thing.

Is levelDB libraries missing or something?

So 7.1, 8.0, 8.1 all don't work now after uninstalling/wiping everything.

Then I logged into the admin account and installed it... that did run!

so, back to regular account, ran it... and it worked!

Then I stopped it, re-started it, and... it does the same thing and can't initialise the database :/

Can't work out what's going on at all.

So I started changing permissions of the roaming folder. change the ownership to the user account, and set full control for everyone.... same result. thing is that the file and folders were created OK anyway when deleted.

Next I change the data directory to another HDD... finally it worked.
Restarted... still working.

So for some reason it will no longer work where it's supposed to. Not too much of a loss though, means I save space on the SDD moving it to the big HDD.

I got this error today after using 8.2 for about 12 hrs. Couple of clean shutdowns and launches no problem, then tonight the error popped up out of the blue. Re-downloading the block chain now..

I also see this on 8.2 today after a couple weeks of using an 8.2 (rc and then release) without a problem.

A friend of mine with a new Macbook Air SSD having the same issue about 1 out of 5 launches it says the block chain is corrupt with Bitcoin 0.8.2

Are the other people having this issue also using a SSD?

No SSD on my failure.

Unfortunately, yes.

I had so many corruption problems with 0.8.1 that I decided to downgrade to 0.7.2 until the known issues were resolved.

Now that 0.8.2 is released I decided to give it a try and unfortunately it's now crashed with database corruptions twice.

0.8.2 is definitely running better than the previous 0.8 Mac releases I tried, but there are definitely still problems.  I was going to wait and see a bit before I start publicly complaining, but yes, since you asked I'm having problems as well.

Ok, I've now had three database corruption crashes with 0.8.2 Mac client.  This is the only interesting line in debug.log is:

Code:

Verifying last 288 blocks at level 3
LevelDB read failure: Corruption: block checksum mismatch

From what I've seen on github, LevelDB corruption issues were supposed to be resolved in the 0.8.2 release and now 0.8.2 is listed with no known issues.

Can someone with a github account please submit an issue report for this?

From what I've seen, we've had no real stable Mac client release since 0.7.2 so it would be nice to get whatever bug is causing this LevelDB corruption finally squashed.

I had this same problem. Then I realized when I copied the files some were as root owner. I did a

Code:

chmod -R [username] *

and the problem was solved.

Ok, github account created, and my version of this issue reported:

https://github.com/bitcoin/bitcoin/issues/2770

[cypherdoc]

just got back from vacation and find my server shutdown.  0.8.2

upon reboot, i get this same error:

Code:

: Error opening block database.
Do you want to rebuild the block database now?

is there an easier way to rebuild db w/o deleting and redownloading?

[cypherdoc]

now i get the same "reindexing" or rebuild problem out of the blue on my Bitcoin Qt Mac version 0.8.3.  

in the last post, this same error occurred in Ubuntu with Bitcoind 0.8.2.

this is really a problem that needs to be fixed.

i got the ""Error opening block database. Do you want to rebuild the block database now?"

Try aborting then restarting your computer.
worked the last time this happened to me.

im already re indexing i had someone send me a coin a few days ago. whats the chances it was lost?

[LaserHorse]

zero, if the transaction was recorded in the blockchain.

thanks so much thats a relief... now to learn about how to downgrade and do a work around. or keep BTC on a android or something. windows/android seems to be what everyone uses when hacked.. cant win it all.

You don't need to run Bitcoin-Qt. You can use Electrum or Multibit.

[DrahogErusiel]

could i have my BTC transfer without finishing my blockchain in QT? I have a coin that was sent to me i have not received yet. could using Multibit or electrum intercept it? or should i wait?

also what one would people recommend? Electrum or Multibit?

[rupy]

Ok, this is ridiculous!

1) Can't stop bitcoind with ./bitcoind stop; it replies "error: bla bla bla" (can't remember)..
2) Shuts down via jsonrpc and bitcoind process just sits there with 0% cpu though port is closed
3) Kills -9 process then this thread!?

So WTF now, delete database? I don't wan't to redownload whole blockchain after each "failed" restart of bitcoind?!?

Why is bitcoind asking a question you can't reply to?

EDIT: Currently reindexing, it's connectable, we'll see how that goes... funny thing bitcoind reports negative balance while indexing...
