I am new to TrueNAS and have been using it for almost 1 year. I recently felt my server (hard drive) is making strange noise and I got the following alerts when I logged in.
I did some research online and performed the SMART short test and long/extended test. Here is the result after the test has finished.
I also got another alert once the test finished.
In my setup, there are 2 Seagate EXOS 18TB drives running in mirror mode. The hardware is an old Dell workstation (Precision E1650) running VMware EXSi 7 with HBA passthrough. The server is running almost continuously over the past 9 months (I turn it off for maintenance occasionally). It is also plugged into an UPS, so there is not many hard shutdown.
Other than the Critical alerts, I don't think there are any data errors reported by ZFS so far. But the unusual noise of the machine makes me kinda uncomfortable (it sounds like the disk is keep seeking or performing large amount of random IO, but I am sure it doesn't as our workload hasn't changed, and the machine sounds normal during the SMART long test). What should I do next? Should I replace the disk? Thanks
