Hello guys,
I'm using TrueNAS last two years, so I can say I'm quite new on this system. Few weeks ago I noticed that two of the disks started showing some errors on read status, because of this the pool goes to unhealthy state, but if I reboot it again goes to healthy.
I know that ZFS will try to self-heal the filesystem, but I'm not sure how to handle this situation.
For instance, in the past I used QNAP and when there is a issue with the disk, it simply mark it as offline, so you are required to replace.
Here I have only these errors reported by S.M.A.R.T but nothing else. I also checked the disks via CLI commands with the help of this article: https://www.thomas-krenn.com/en/wiki/Analyzing_a_Faulty_Hard_Disk_using_Smartctl but I cannot see anything which I have to worry about.
I have none of these:
Please check the code below:
