There are a little bit problem. On local machine (own), all works fine, but, since I moved my projects to VPS (you know, internet all the time, electricy backups and so on), I notified, that a lot of programs aren't work or aren't work properly. I couldn't check SMART on my VPS
sudo apt-get install smartmontools sudo smartctl --all /dev/sda
results: smartctl open device: /dev/sda failed: No such device
So, how can I check SMART and performance on VPS?
