I received an alert indicating that one of the disks has 8 unreadable and uncorrectable sectors. With me being brand new to ZFS and TrueNAS, I did some research to try to figure out what this all means (I assumed failing disk, but wanted to be sure). I found others with similar errors and the common request was to run the "smartctl" for additional information.
I ran it on the problematic drive first for obvious reasons, but my curiosity led me to run it on the others. I found a comment indicating that a non-zero Raw_Read_Error_Rate value is a sign of a failing disk. To my surprise, all 4 of my disks have seemingly high values which has caused me some concern. For reference, 2 of the disks are approaching 5 years old and the other 2 are new (all four are 4TB Seagate Ironwolf NAS drives).
For what it's worth, I have scrub tasks set to run every 7 days and long S.M.A.R.T. tests set to run monthly. I've had no issues pop up until now, though admittedly my journey with TrueNAS started about 2 months ago...
The "smartctl" results for all four disks below (TrueNAS alerted me to the issue identified in Disk 4 - sde). Are any, or all, of my disks failing? I'd be very appreciative of any support that this community is able to provide!
