I’ve had a home server for years, at first using Windows Server, then Unraid, and now using Ubuntu server. I’ve long known that I should keep a close eye on my spinning rust, but I never really knew the best way to have that monitoring quietly automated in the background, only sending me a message when something bad shows up. If it matters at all (I assume it doesn’t) I am using ZFS on Ubuntu (but not using ZFS as root. It’s mounted in e.g ~/user/storage. My primary drive is an SSD)
What are you all using for hard drive monitoring? What are you using for notifications and (generally) how are you linking those two together?
If you want regular automatic hdd checks and don’t need a WebUI I recommend https://github.com/smartmontools
So just as an FYI to those who trust these sorts of things, SMART technology is a self reporting thing. The hard drive is more than capable of lying to the data in that system if it protects the manufacture from responsibility of replacing faulty drives. Whats more, it’s actually pretty rare that SMART reports and issue before the drive just sorta… dies someway or another.
It’s not useless technology, but it’s pretty damn close. I don’t even both with any of my setups. I test it by monitoring if the server has issues reading/writing. SMART wont tell me anything before that will.

Okay, but how do you monitor the issues with reading and writing?
SMART value monitoring helped me finding faulty drives, not only once. And drives are tested before adding to a production system.
Certainly system drives are separate from data drives. The latter can be perfectly monitored by SMART values.
Have done years of enterprise fault analysis, I promise you that SMART will happily tell you there is a problem at the same time you begin to experience data corruption. You might get lucky and catch and altered sector count spike up, or a temperature value go out of family, but in the field those things really suck at predictions.
If you want to know if a drive is healthy, track data corruption at the file system layer.
