I am a bit new in proxmox, and wanted to ask, if there is anyway I can pull SMART information through the gui, and not via CLI, so that I can have them more accessible.
You can view the current SMART values of each disk of your node in the GUI:
Datacenter -> Node (select your node by name) -> Disks -> select a disk and click on 'Show S.M.A.R.T. values'
