Is that mean that the parity1 is still valid? I didn't know that both parity were somehow not tied together.
Also, how did you find this information, I would like to be able to diagnose it in the future.
Please tell me if I'm wrong, but my understanding was that pending sectors were marked as so when the drive was unable to read data from those sector (and would attempt to recover the data later).
With that understanding, I was under the impression that the 8 pending sectors would likely cause the 7 parity sync errors.
However, now you are suggesting a correcting check. This check will use drives data to rebuild the parity, right?
So I'm worried that if some data is not recoverable on disk3, it will prevent me to getting it back from the parity.
On the other hand, if the parity is really invalid and the data on disk3 is fine, attempting to rebuild the drive will cause some data corruption/loss.
Is there's a way to certain of the proper course of actions?
Thanks for you time and your help!
PS: Writing this give me a new idea, that might allow me to be certain that the data will be saved.
Excluding disk3 from all my shares, to prevent any data change on the drive.
Find a way to run a checksum on all the files of the drive.
Replace the disk3, with the new drive and reconstruct it (keep old disk3 in a safe spot for now).
Re-run the checksum on all the reconstructed files of the drive.
Diff the 2 list of files and ensure that everything is identical
However, writing those bullet points make me wonder what would be the interpretation of those result if the data is not identical on those 2 lists... disk3 or parity is bad?
