Im looking at installing Proxmox on my linux box (TR 3960X) instead of Ubuntu. I wish to put Proxmox on a 1TB NVME and would like to RAID 0 the 6 2TB NVME drives. Is this possible? I have been looking at tutorials and cannot find one for RAID 0 as most use ZFS for RAID but Proxmox does not offer RAID 0 in the tutorials.

Is it possible to just RAID them using the command line(mdadm?) and have Proxmox see the RAID as 1 disk?

Thanks

Thank you for your reply

I am trying to do this but cannot get it working.

I used the shell and ran:
--pvcreate -v /dev/nvme[0-5]n1
--vgcreate -v storage /dev/nvme[0-5]n1
--lvcreate -l 100%FREE -n stripedStorage -i6 storage

when I do this, I can only see storage and it shows as 100% used, I do not have access to striped storage?

what am I doing wrong?

Thanks

I had seen this and tried

--mdadm --create --verbose /dev/md0 --level=0 --raid-devices=6 /dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1 /dev/nvme4n1 /dev/nvme5n1

md0 does not come up as an option in the GUI to use for creating a LVM Volume Group?

EDIT:

Think I may have it, created the volume group via command line and it now shows up in the GUI for use

This worked. FYI for mdadm make sure you create a partition on the drives first and raid the partitions IE /dev/nvme2n1p1 etc or it will not survive reboot. Works like a charm now, Ubuntu VM installed in seconds :)
 
They are all basically scratch VMs so im good with that but i can bring them up/tear down etc VERY fast, purpose to the striping :)
