It’s just a backup, but the file is corrupt so I don’t think you can do much with it anyway. I just don’t like deleting stuff until we know it’s all fixed.
That seems fixable though. What version was your node running on when you first encountered the error and did you update it in the mean time? It seems it’s trying to do some migration steps. We may have to drop the index. Let me have a look at the code, I’ll get back to you.
It’s working now. Node is at version 1.10.1. Thank you very much. If I knew this was so easy to do, then I would not feel so bad about this. I was very afraid to lose those 2 months of node progress.
Most issues that don’t involve actual data loss can be fixed as long as your node hasn’t been disqualified yet. So yeah, don’t stress, we can usually help you fix things.
