Corrupted Database: Is --reindex the only option?

November 30, 2015, 02:05:34 PM

I've tried restarting with --rescan, but get this:

2015-11-30 13:34:22 Verifying last 288 blocks at level 3
2015-11-30 13:34:22 ERROR: DisconnectBlock() : added transaction mismatch? database corrupted

2015-11-30 13:35:29 : Corrupted block database detected.

The last time I had to do a --reindex it took 4-5 days to complete, and that's a long time to be down. Any other options? Should --reindex take that long?

Also, I do have the blocks and chainstate directories backed up as of a month ago. Would replacing the current directories (and only those two directories) with the backups be safe?

Yes, that would be safe

Yes, it would be safe and faster than -reindex but make sure to backup your wallet.dat before doing anything.
