The hard drive's SMART is normal.
I feel that there is a problem with a certain block of the hard disk. Is there a solution?
Thanks a lot.
Thank you very much for your reply.
I tried to use the dd_rescue tool for bitwise copying.
This is followed by re-creating the degraded array with --assume-clean and then adding a new disk.
Any effect, I will come back again.
The firmware currently in use is V5.21 (AATB.3)
I am not sure how to give instructions to ensure that data is not lost and restore the RAID mechanism. Can you please help?
ex: mdadm --create --assume-clean?
My situation is the same as described above. I can't read sector 41578064. What complete instructions should I use without triggering this error again?
I making a bitwise copy from disk sdd to a new disk, using dd_rescue or a similar tool.
I want to know what instructions can be re-create the degraded array manually with the new disk, and using --assume-clean.
dd_rescue I've run it a few days ago, my current situation is: the original 2 disks and the bit-copy hard disk,
I can see the RAID when I boot, but I have to insert a new hard disk to let him It is a normal four-disk RAID5 mechanism,
but the error that occurred at the beginning will still occur. The new hard disk that I copied using dd_rescue still has the error of the disk sector.
Is there an error to skip and allow the new hard disk to rebuild RAID What about the instructions?
Just like you said above:
So it is possible that if you re-create this (degraded) array from the command line, using --assume-clean, that you can copy away al your files, without triggering this error again.
