Just replying back for help on the others in the future. Success! I ran the extended smart tests (took most of a day) ad show 0 errors for either disk. I then followed the above steps and rebuild started. Took around 32 hours and when complete both disks now happily back in service. Thanks for the help. I'll mark as solved.

Thanks - that's what I mean't set to no device. I'm just running extended SMART tests and if they return with no issues I'll follow above instructions. Thank you

Thank you @trurl. No I did a smart short test and nothing showed up. I'm pretty sure I'm not using any power splitters. So what should be the steps to rebuild if I want to rebuild both at the same time? is it? Stop the array. Remove both drives, mark as empty. Start the array. Stop the array Re-add the disks into the empty slots Start the array Wait for rebuild Is that right?

Attached are my diagnostics but it was captured after a reboot sadly. By mistake I powered down the machine which wiped the logs. Gah. The system still shows the two failed drives, but the error count has been reset to 0. big-john-diagnostics-20250114-1500.zip

Hi all - I'm looking for help on the best way to recover from this issue. Last night I had errors on 2 disks at pretty much the same time. I think first was one of my data drives with 8 errors, then one of my Parity disks pretty much immediately had 1700 errors. I'm now in an emulated state (fortunately have a second parity). What I'm not sure about is how to recover from this. Question 1: What should be the best sequence to get me back to a healthy state The data drive that has an error I've had for a number of years. the Toshiba parity disk I only got about a month ago from SPD and did a pre-clean with no issues. Parity check on Jan 1st showed no errors either. Could it be my cables? Question 2: Is there more I should look into to prevent re-occuring? e.g. change cables? RMA the drive.
