I was trying to monitor s.m.a.r.t. values - especially temperature - of the HDD drives (Seagate 5TB) in Gemini 2.5 V2. There's a great piece of software called smartmontools, that can do that.
When I only had ONE Seagate drive installed, this worked flawlessly - I got a long list of s.m.a.r.t values on the command line output. I guess, it would work with two internal drives as well, as long as they stay "separate".
But when I installed the second drive and "merged" them both via RAID0, smartmontools could not display any s.m.a.r.t values anymore
It did recognize the raid controller, though, and reported, that there is a s.m.a.r.t. capability (see below).
Does anyone know, how I get smartmontools working with the raid0 disc? There is an output of possible option switches, that just would have be to set to the right controller option.... So maybe, if I get the proper command line arguments, I'll succed - it would be in the form
sudo smartctl -A -d OPTION-ARGUMENT /dev/sda
So here's the informational output created via sudo smartctl -i /dev/sda
