Run Proxmox with NVME RAID

Unfortunately it is not possible to run Proxmox with VROC until today 15.1.2020. The support by Proxmox and Intel is insufficient, there is a lack of usable drivers and support. We deliberately do not want to use a software RAID. Nevertheless, we do not want to do without a fast NVME RAID. Note that we do not guarantee this manual and that this configuration is not officially supported by Proxmox. Use it at your own risk!

To use NVME RAID you need the following:

  • Fast server with PCI-E x16 GEN3
  • Highpoint SSD7101A-1 RAID controller with NVME disks
  • Normal hard disk or SSD drives
  • The two installation files of Highpoint
  • The proxmox_kernel_rebuild.sh script

 

  1. Now start installing Proxmox on your hard drives. After you have installed and configured Proxmox you now need to compile the NVME drivers for Proxmox.
  2. Use the script below, save it as proxmox_kernel_rebuild.sh and run it. Attention this process can take several hours! 
  3. Now install the just created /pve-kernel/pve-headers-5.3.13-1*.deb and the /pve-kernel/pve-kernel-5.3.13-1*.deb Attention this process can take several hours! 
  4. If the kernel could not be installed even after 4h waiting time, install GRUB and abort after 4h with “CTRL + C” and start point 3 again.
    apt-get install grub
  5. Restart the server
  6. Now block further kernel updates (IMPORTANT):
    apt-mark hold pve-headers-5.3.13-1
    apt-mark hold pve-kernel-5.3.13-1
  7. Now install the two Linux drivers from Highpoint:
    ./rsnvme_linux_src_v1.2.18_19_12_11
    ./RAID_Manage_Linux_v2.3.14_17_07_26

 

 

INFO: If you ever want to update your kernel, just start at point 2 again and let the new kernel compile.
