Hi I need some help with Proxmox. If you can please redirect me to useful ressources (I read the official Doku but it didn't really help)

I am having problem understanding the different types of storages and how to access them in a vm for example. Example words are:

• ZFS, ISCI, LVM, LVM-thin...
• Bus Controller (Virtio SCSI, IDE,... )

I feel like these are basic topics but I don't seem to understand anything. My latest problem was me trying to pass a third of an ssd (1TB) an another 128 GB from another ssd. I wanted to use the small volume as boot and the big volume as slow storage in a Windows vm but I got an error message about a bus beeing used multiple times. [sorry I don't have the config anymore]

So if someone could redirect me to sth which would help me understand the whole storage virtualization and storage config for vms topic, I would be very grateful.

Thank you in advanced kind stranger.

Okay I saw this posted a lot and apparently it is pretty common but why do people virtualize your nas in for example a proxmox server/cluster. If that goes down it gets super hard to get your data back than if you do it bare Metal, doesn't it? Are people only doing it so save on seperate devices or are my concerns unreasonable?
