[PVE-User] NVMe - RAID Z - Proxmox

[lord_Niedzwiedz]

         Good morning,

After a longer (unfortunately) fight, I was able to install on your 
Proxmox server on RAIDZ from 1 to 3.
To do this I had to change some settings in the BIOS (the system did not 
want to start without the "legacy" option).

And manually edit the MBR on each of the disks.

root at gandalf8:~# sfdisk -d /dev/nvme0n1         (drives from nvme0n1 to 
nvme5n1)
label: gpt
label-id: AD03123E-3D5D-4FD2-A7F3-9B6247F88CEA
device: / dev / nvme0n1
unit: sectors
first-lba: 34        (this must be necesary set)
last-lba: 976773134

/dev/nvme0n1p1: start = 34, size = 2014, type = 
21686148-6449-6E6F-744E-656564454649, uuid = 
CA6B9D71-BFEC-4EC2-8DB5-BB79B426D20D

cfdisk - the first sector must begin:         Start 34 End 2047
Example for disk 500GB.

10007K                2014S                          BIOS boot
465.8G                976754702S                Solaris / usr & Apple ZFS
8M                       16385S                        Solaris reserved 1

And so for 5 drives.

Without this, the proxmox crashed at the installation every time.
