Hello:
I understand that parity calculations are not done as part of Raid5
read operation in normal running conditions.
However, it would be done during disk failure or when a sector is bad.
Is there a way (any stats) available to see if parity cal are done
when sector is bad (since this is not as obvious as a disk fail...)
Thanks!
