Hi guys,

i have a really hard time installing ProxMox 4 to a Quanta sever with DA0S2MMB8B0 motherboard (with 3 TB SATA disks). The motherboard supposedly supports booting in legacy and UEFI mode.

With legacy, it never boots automatically (even with 1TB disks, I always have to select the disk manually using BIOS select - F11). With UEFI mode it works automatically only for LVM installs. It fails to automatically boot when I try ZFS install. Again I can manually select the disk in the BIOS with F11, and it works. The difference I observe is with missing EFI partition.

Is there a way to get ZFS install with EFI partition and install grub there, so I can get it booting automatically?

Click to expand...

our installer currently does not support ZFS+EFI (because the EFI boot partition can only be mounted and updated once by Grub). booting in BIOS/legacy mode should be possible, but note that we only install Grub on the first (pair) of disks, so depending on your ZFS pool layout you will need to set the boot priorities in the BIOS accordingly.
 
Thank you for your response.

I would use legacy/BIOS option, but BIOS (there are no available upgrades for DA0S2MMB8B0) just does not boot PM in legacy mode and I have no idea why. Will look a bit more into this and maybe ask some more questions, probably in a new thread.
