Dear Chris Murphy,

In message [ref] you wrote:

Well, you have a block on each drive that's supposed to be identical,
and if there's a mismatch that means they're not identical and it's
ambiguous which one is correct. So if the data on the drives is
unimportant to retrieve correctly, then I guess it's not a critical
error.

Heh, would I be running a RAID 6 array if the data was unimportant?

What's the smartctl -a look like for all drives? I imagine one or more
have bad sectors, ECC errors, or UDMA/CRD errors.

I see a some Hardware_ECC_Recovered; very few disks have 1
Reallocated_Sector_Ct; there are no (0) Current_Pending_Sector,
Offline_Uncorrectable, UDMA_CRC_Error_Count, Multi_Zone_Error_Rate, or
Data_Address_Mark_Errs.

Best regards,

Wolfgang Denk
