Best practice for installation on a hardware raid system

[fredriksk]

Hello
So, Im a totaly n00b on virtulasion but you got to start somewhere and why not on proxmox.

I have come across a Fujitsu Primergy RX2540 server. an old one that I think of using for som testing and learning. It contains a hardware raid controller. My first test would be to sett up two virtuals server. One running a trueNAS server and one running a docker server.

My first question is. Should I try to inactivate/remove the Raid controller? I'm thinking that mabie proxmox will run best on a seperate disc? And what if I set up trueNAS on the hardware raid controller? Will that cause problem?

Depending on the used controller, you can flash it to IT / HBA mode in order to use it with ZFS, otherwise, just install it with thin LVM or EXT4 and your're fine. How many disks are there?

I suggest to use as is with hardware controller, especially if you are just learning.
That's how I started with Proxmox VE, and I still have some servers with hardware RAID in production.
I recommend separate small ssd (or 2 ssds) for the OS install.
But I had in the past also booted off the raid controller (created a small volume for the OS). YMMV, depends on controller.

The reason behind this is just to reinstall everything WITHOUT loosing your VM data (but configuration) that is stored on the other storage if you need to reinstall.
