The boot volume state is DEGRADED

[Andrew Ostrom]

I recently built my first Freenas system. I started with a Supermicro chassis/server and went from there. I am having two issues, I will post two threads since they are completely different issues.

First - no matter how I do it i keep getting this message:

The boot volume state is DEGRADED: One or more devices has experienced an error resulting in data corruption. Applications may be affected.​

Here is my configuration:

Supermicro SuperChassis 846E1-R1200B​

X9DRi-F Motherboard​

Dual Intel Xeon E5-2620 15M 2Ghz Six Core Processors​

128GB ECC Ram (16x 8GB PC3-12800R)​

LSI SAS-9207-8i​

BPN-SAS2-846EL1 Backplane​

Dual PWS-1K21P-1R 1200W 80 Gold Plus Power Supplies​

2 x Sandisk SSD Plus 120GB SSD (boot pool)​

8 x Seagate Constellation ES.3 3TB SAS RaidZ2​

6 x Seagate Constellation ES.3 3TB SAS + 2 x Hitachi DT01ACA300 3TB RaidZ2​

5 x Seagate Constellation ES.3 SAS + 3 Seagate IronWolf 4TB RaidZ2​

​

When I installed Freenas I used the two SSDs in a mirrored config. Everything went fine and then a day (maybe less) later I got an alert that the boot pool was degraded because of an error on the /dev/ada1 SSD. SanDisk doesn't have a diagnostic for BSD, so I pulled the two drives, installed them in a Windows box and ran the SanDisk test utility. I also ran a variety of Windows-based tools to try to stress test the drives. The utilities , and SMART, show no errors. I reinstalled in the Unix box, reinstalled Freenas, and within a day it dropped /dev/ada1 again. I have tried multiple SATA cables, no change. Here is smartctl -x output:

root@freenas[~]# smartctl -x /dev/ada1​

Any ideas what's wrong and why this keeps going off line. The system is running fine on /dev/ada0, which is the identical drive.
