Hi,
I got this error on my freenas (CRITICAL: Device: /dev/ada3, ATA error count increased from 0 to 1), ada3 is my L2ARC drive, so I'm not super worried, I just wanted to know if anyone has some insight as to why this is happening. If you have any advice or words of caution I'd appreciate it. Thanks!
I ran smartctl -a /dev/ada3 and this the output:
