Chose Cancel. The .sst file referenced did not exist, but no problem creating the .sst file with Cygwin "touch".

Developers have tweaked DB parameters in order to comply with older 0.7 client limitations and it seems like LevelDB started complaining. It only affects 0.8.0 to 0.8.1 upgrade. Solution is given by @inglian a few posts up. Hope it helps. Title: Re: "Error opening block database. Do you want to rebuild the block database now?"

My question was rather if I have to re-download the whole block chain now or if there's a way to repair it somehow. Anyhow, this is really strange and right now weakens my trust in the official client. I really hope that the problem is on my side (SSD defect?) and not within the current client, that would be really bad. Title: Re: "Error opening block database. Do you want to rebuild the block database now?" Post by: JustJake on April 01, 2013, 09:24:34 PM I have gone from scratch several times and have even grabbed the torrent of the blockchain to see if it would load more smoothly pulling transactions from the .dat file instead of downloading from peers. I get a checksum error every single time and it is never in the same place so I know that it isn't like there is some embedded corruption. I do appreciate that the blockchain loads significantly faster than in 0.7 days but I would prefer it loading correctly as well.

The masses should learn to backup their wallet and the bitcoin folder itself. 7zip is free software (but please make a donation if you can, its good software ) http://www.7-zip.org/download.html There may be software available to do it automatically. If not, just for the sake of bitcoin, it should be made. I dont believe in the online wallet thing. Title: Will this work? Post by: mobile4ever on April 02, 2013, 08:41:14 PM Will this work?
Download the blockchain and then upload it to one of those download sites. It wont be totally current, but it may be faster than having to wait for the bitcoin wallet to redownload it. The uploader may even make some money off of it. Title: Re: Will this work? Post by: maxmint on April 02, 2013, 08:59:34 PM Will this work?

The uploader may even make some money off of it. I now keep a local backup copy of the block chain, so in case of getting errors again I can copy over my backup.

Post by: maxmint on April 11, 2013, 11:44:20 AM ... and I get the same error again. I had it about 3 weeks ago, decided to re-download the whole blockchain and not get the same error again.
I don't have any idea on what could be causing this. Title: Re: "Error opening block database. Do you want to rebuild the block database now?" Post by: salfter on April 17, 2013, 02:49:10 PM Just opened 0.8.1 after having successfully opened it a few times and received: "Error opening block database. Do you want to rebuild the block database now?" I started getting this error today on a machine on which I had upgraded LibreOffice to 4.0. litecoind and litecoin-qt were throwing database-related exceptions as well. The LibreOffice upgrade pulled in a newer version of Boost, which meant everything else that uses Boost (including *coind and *coin-qt) needed to be rebuilt as well. No problem, right? Gentoo is good at this sort of thing. It looks like there's some interaction between Boost and the database used such that the on-disk format changed in a way that *coind/*coin-qt don't like. AFAICT, the only thing likely to get it running again is to redownload the blockchain. I moved .litecoin to a safe location, created a new .litecoin directory, copied over my litecoin.conf and wallet.dat, and am now letting litecoin-qt pull in the blockchain again. It's set to only talk to the litecoind on my mining rig, so the transfer's only running across the LAN and should be done in less than a half-hour. It's halfway done as I write this; if it ends up working properly, I'll do the same thing with bitcoin-qt. Title: Re: "Error opening block database. Do you want to rebuild the block database now?" Post by: maxmint on April 22, 2013, 06:17:18 AM Wow, this is really getting annoying. Had the same error again, tried rebuilding the database which made bitcoin-qt completely crash.
Downloaded new block chain and now getting "wallet.dat corrupt, salvage failed". Any hints on what could be causing this? Bitcoin-qt is almost unusable for me, since I have to redownload the block chain every week. Also reported this here at github (https://github.com/bitcoin/bitcoin/issues/2435). Title: Re: "Error opening block database. Do you want to rebuild the block database now?" Post by: seleme on April 29, 2013, 02:28:56 AM I got it now too

It took a little longer to pull the Litecoin blockchain through (and it took a few hours to rebuild the Bitcoin blockchain), but it beats having to download them from outside the LAN.

Then I logged into the admin account and installed it... that did run! so, back to regular account, ran it... and it worked!

Post by: P_Shep on May 17, 2013, 12:01:16 PM 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. Title: Re: "Error opening block database. Do you want to rebuild the block database now?"

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. Title: Re: "Error opening block database.

This is the only interesting line in debug.log is:
Code: Verifying last 288 blocks at level 3 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.

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?

Not sure if it was introduced in the update to 0.8.4. I've run with the -reindex flag, deleted the chainstore directory and let the system rebuild it and also removed the entire home directory and let it re-sync the entire blockchain.

I wonder— is everyone having frequent problems on OSX running filevault? No, not filevault. However when I first set up the client on version 0.6.3 I moved the contents of the Bitcoin directory into an encrypted disc image and hard linked the contents back into the original location. This meant that every time I needed to run Bitcoin-Qt I had to open the disc image first. Of course now that I have encountered this error and looked into the file structure again I realise that it has changed. Doh. Oh well, this has still worked faultlessly until now. Since posting about the error I have restored all the files to the Bitcoin directory from a backup and also restored the 0.8.4 application. I ran it with the checklevel=2 commandline option. It is now stuck at the "Verifying blocks..." stage and has been for more than 30 hours. It seems to be creating and removing files ending in .sst in the "chainstate" directory (for example 068675.sst) continuously. This seems like a very long time, and a little concerning tbh. I'm starting to wonder if it might be better to simply delete the Bitcoin directory, re-download the blockchain, then copy the wallet.dat file back when it's finished ???

I am now on my 3rd reindex, and to make matters worse, have forgotten some of my wallet encryption passphrase. But that is a different post. What is giving me cause for concern now is the fact there is a post on here which says 0.8.5 solves the problem, but now I am seeing users of 0.8.5 with the same problem. WTF is going on?

This happens any time I close and then reopen Bitcoin-Qt. I was having an issue with another application last night, so I manually closed it and all other applications (including Qt) and rebooted. Sure enough, when I reopened Qt, it prompted me to re-index (which takes several overnight sessions with my processor pinned near 100%). My entire system is backed up, so this time I closed Qt and restored the .../Application Support/Bitcoin/ directory, and then re-opened Qt and received a different error that I stupidly closed because I was so pissed. Instead I RErestored back to the unindexed version that existed and just let the reindex start. Again. Is there some issue that prevents the data directory from being restored from backup?

Title: Re: "Error opening block database. Do you want to rebuild the block database now?" Post by: carly200 on December 20, 2013, 08:23:16 PM Hi,
I have a similar issue, that appeared suddenly, and I am unable to fix/debug it on my own. Maybe you can help. My environment is a Win8.1 Laptop with an SSD, and I am running Bitcoin and Litecoin QT clients. Since space on SSD is "spare", I moved the datadirectory to a permanently inserted SDXC card (exFat) months ago. To avoid accidental database corruption (ejecting SD-card; windows hibernation, etc), I keep a backup of the data directory, that I make ~ once a month and that I can use to start off again, if something goes wrong. Recently both BTC and LTC QT got an update to 0.8.6/0.8.6.1 and worked like a charm, until now. After syncing and (I think proper) shutdown, I wanted to start the software yesterday morning and it ended with the "Error opening block database. Do you want to rebuild the block database now?" error. neither clicking ok to reindex, nor aborting gets me back at my db. I tried several recovery (e.g. going back to my backup), they all failed. I now focused on the litecon-qt since blockchain size and folder copying/indexing does not take days, but it seems BTC and LTC behave the same. Even deleting the whole directory (keeping/discarding wallet.dat) before starting, results in the same error when using the datadir on the SD card (which worked fine before). Now I went back to my main SSD and removed the "datadir" back to default, and redownloaded the blockchain. moving it to other drives (even network mounted drives) works, but the moment I move it to the SD card, the client ends with the error message. I have 50GB of free space on the SD card and ran disk-check tools. Also I verified that the card is working by running write/read tests. the card seems ok. what can cause this issue? I am posting the Litecon debug info (please bear with me), since i am running tests for filesize/copy-speed limitations witht litecoin right now, as I think it is the same error: Code: 2013-12-20 20:06:12 Litecoin version v0.8.6.1-beta (2013-12-05 22:52:50 -1000) Can anybody help?

Title: Re: "Error opening block database. Do you want to rebuild the block database now?" Post by: argaostar on August 21, 2014, 09:20:07 AM Hello guys, I will try to lift this thread and tell a story about a strange behavior on my PC two days ago.
I have had bitcoin core on my PC for just a few days. I believe it all started with with FSX Flightsimulator did not start up. I made a repair on it, and was reading tips on the net how to get it up and running again. I was not able to solve it that night, and closed down the computer. The next morning i connected to the net, Mozilla Firefox would not start. Or, I got the message it was already up and running, but it did not respond. Following advices on Mozillas home page did not help, it was not to be seen in task manager, or not possible to close it anywhere. So I uninstalled it and reinstalled the program. Then it worked fine. What I discovered at the same time, was that several icons on my desktop had disappeared. And today when I wanted to open bitcoin-core, the icon was gone, even on the start menu. I had to go to the files, and start it from the exe file. When starting, I got the messages you guys had here. Made a try a couple of times, and downloaded a new one, but same result. Looking in the file folder, I find only these files: daemon doc bitcoin-qt.exe copying.txt readme.txt uninstall.exe Should it not be more files? Now, this morning I am trembling of nervousity, have I lost my bitcoins?? The HDD is only one year old, I have 300 Gb of free space. Yesterday I did a maintenance with AVG PC Tune up and Bitdefender. That was after the icons disappeared on the desktop. Can also mention that AVG PC Tune up, also have a strange behavior today. It give a error message and ask if I want to send a report. Then it crashes. I guess it will not help to make a system recovery? Been working with computers for many years, but this is a new experience. If I have lost the bitcoins, as I today understand, probably is stored on the pc, I am in chock. Tried to read through this thread, but can not keep my mind clear. Besides it seems like my problem here is of an another dimension. I use Bitdefender total security, but still, there could be a hidden intruding from outside.... Title: Re: "Error opening block database. Do you want to rebuild the block database now?"

Title: Re: "Error opening block database. Do you want to rebuild the block database now?" Post by: Richy_T on August 05, 2015, 01:18:27 AM Just had this happen to me. Latest version of bitcoin on Linux. Halted the bitcoind with "bitcoin-cli stop" so it should have been clean. Currently trying the reindex.
Grrr. It started downloading the blockchain all over again :/ (Edit: It wasn't downloading the blockchain, just regenerating the rev*.dat files) If it makes any difference, the blocks and chainstate directories are symlinked from elsewhere. Is there something in that that could be causing it? I mention it because the person is having trouble with the SD card. Could we get more info on what triggers this error? Never mind. Disk space issue... Title: Re: "Error opening block database. Do you want to rebuild the block database now?" Post by: Richy_T on August 05, 2015, 03:04:14 PM Reindexing was taking forever. It's now about 12 hours later and I was still only caught up to Feb.
I guess the lesson is to backup your blocks and chainstate directories (which fortunately, I did or rather had a copy for a different instance of bitcoind). That represents work which is hard and slow to recover. Title: Re: "Error opening block database. Do you want to rebuild the block database now?"

So it is likely to be an HD issue I guess rather than client issue as nobody has reported it? Could I mount (linux) a flash disk (64GB) and place datadir there?

You have a (very) slim chance that your wallet is still available somewhere on the disk. First of all, stop using your computer. The more you use your computer, the larger the possibility that your wallet is overwritten. If possible move your HD to another computer. Then install one of the existing programs for recovery of deleted files on this new computer (on his old disc, not on the moved disc with deleted wallet). There are some solutions on the market but cannot talk about them since i never used any of them. If you're lucky, your wallet might still be intact since the deletion just removes the reference to the file but not the file itself. But if even a single bit is changed on that file, you will not be able to recover it. Good luck. you should email yourself your private keys and pass phrase.or whatever other information. even if your computer gets destroyed you can still recover your email from a different device This is very bad advice for one simple reason - anyone who has the access to your mail also has the access to your funds. You have to backup passphrase and private keys, but mailing them is the last possible way you should do it. |
