Scheduled Parity Check

Then you should try to find out what caused the sync errors, only acceptable result is 0 sync errors, run a non correcting check, and scheduled checks should also be non correcting.

How will I know what caused the errors?

Will syslog contain errors?

Can I write to array while check is running?

If there was no unclean shutdown it's a hardware problem, RAM, board, controller, disk, etc.

It only shows the sync errors, not the reason for them, though it can help diagnosing, by comparing with previous errors.

Yes, but array will perform slower.

if the new scan I see more errors what would you recommend? if its the SATA card issue how would I confirm?

Post new diagnostics. If we can compare them in syslog, that would tell what the suspects are. RAM is also a suspect if different parity checks result in different parity errors for example.
