Hi everybody,
I have a question regarding parity and rebuilding a defective drive. I had assumingly a corrupted drive (or at least a drive failure according to unraid dashboard). So I got myself a new drive and swapped it in but now two days later I see, that at least one, I guess two shares are completely empty.
I would like to understand how this could happen, although I have a parity drive? Everything is back green now in Unraid, but, as I said, the entire content of one share is missing.
Please don't tell me, to have backups, I have a backup that I'm currently rolling back for the more important share, but I would rather like to understand, how this happened.
Is it possible, that parity data was written, while the drive was already partly corrupted? Is there (even if I have the most important things) a way to get anything of the data? To me it's even unclear, what exactly is wrong with that drive, it's a 9 months old WD Red (EFAX).
Best regards, maybe someone can help me out (at least to understand the problem).
