The first 8 TB Seagate IronWolf (first HDD position in NAS) started to display "Warning" in the GUI and the HDD SMART info indicted that the "Command_Timeout" was over the threshold at 6 and then after I wiped the HDD prior to shipping, it is now at 8, so error is increasing.

I am sending this HDD back to Seagate for replacement and have removed it from the NAS but now both the Pool and Volume display the error "RAID is Degraded".

Until I get a replacement HDD from Seagate (some weeks), how do I rebuild the Pool and Volume to the remaining 3 HDDs of 8-12-12 HDDs and clear the error "RAID is Degraded"?

I have just gone through this with an 11 month old Ironwolf 4TB. (Also I had a requisite spare to hand as well). Fortunately I bought my drives from Amazon {Prime}. I could find no way to contact Seagate from the UK (The advertised chat link is not there on web site).

Contacted Amazon and after a few minutes with the Amazon rep on chat, he had organised a return, with prepaid shipping label, and issued a "next day" ship order for a new drive. This was on Saturday. The replacement drive arrived yesterday lunchtime and is now in my spares pool awaiting the next incident. Can't complain about that!
