[SOLVED] Possible to setup RAID 0 without RAID controller.

[LittleGrand]

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

RAID0 is a misnomer, since its not Redundant. You can just create one giant LVM pool: https://askubuntu.com/questions/219881/how-can-i-create-one-logical-volume-over-two-disks-using-lvm

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

follow these steps selectively https://pve.proxmox.com/wiki/Logical_Volume_Manager_(LVM)#_create_a_lvm_thin_pool
replace /dev/sdb1 with /dev/md0

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

Ubuntu VM installed in seconds

You will also loose EVERYTHING in seconds, so .... happy computing!

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
