Hello,

My server is Supermicro 5037MR-H8TRF. It has one pci slot and its backplane is faulty, no sata disk can work. Is it possible to move only boot partition to usb flash disk? So Proxmox can be boot from usb flash disk and Proxmox installation and virtual machine data can be run on m.2 nvme plugged pci card.

Thanks in advance.
 
Hello,
yes you can do that. But be advised that the Blades have USB only via a breakout cable and only one break out cable is shipped via bladecenter. Maybe a better option would be to try to boot from the m.2. Or you can use the JUSB2 Header on the motherboard or boot via PXE.

Cheers,
Thomas
 
I used some steps from a tutorial (https://forum.proxmox.com/threads/m...x-boot-tool-lvm-migration-to-new-disk.174952/ ) which tells system partitions can be moved to another disk.

Here is my steps:
- install proxmox to nvme
- install proxmox to usb flash disk (sda)
- boot proxmox from usb flash disk
- remove lvm's from nvme disk
- move pve to nvme disk:
Code:
pvcreate /dev/nvme0n1p3
vgextend pve /dev/nvme0n1p3
pvmove /dev/sda3
vgreduce pve /dev/sda3
pvremove /dev/sda3
- remove sda3 partition with parted
- boot from flash and result:
