Hey there,
yesterday I decided to upgrade my 2 TB HDD to a 4 TB HDD.
Before doing so, I backed up everything, ran a parity check and all was fine (0 errors).
Not too long ago, I did an extended SMART test for the parity disk. Again, everything was fine.
After swapping the discs, the rebuild speed was >100 MB/s.
When I woke up, there were quite some emails with "unRAID Status: Warning [UNRAID] - current pending sector is xxx" and the rebuild process slowed down to < 1MB/s.
A few hours later, the rebuild finished with 85848 errors.
The parity disk now has 337 current pending sectors ( 0 Reallocated sector count).
I already ordered a new HDD to replace the parity disk.
Now my questions:
What is the best way to get a perfectly running system again?
Can I even trust the data that was written during the rebuild or should I erase the whole disc and copy all data from my backup?
When I replace the parity disc, do I have to create a new config to rebuild the parity?
unRAID version: 6.6.5
diagnostic file is attached
Thank you very much in advance!
Cheers,
Nico
