New Install of Proxmox 5.1 ZFS Mirror enters Busybox on first boot

[am45931472]

Just trying to do a basic zfs mirror install of my proxmox 5.1 OS but every time after initial install I get forced into busy box with no rpool found error. I've tried zpool import but no luck.

I know this is a common problem, I know it has to do with how device names are assigned from the system in proxmox 5 which has changed from how it was before PVE 5.

Hardware is Supermicro x9srl-f motherboard and multiple LSI 9207-i8 HBAs.

I've got multiple HBA's in this system, running legacy bios. the USB stick that I use to do the install also gets a Device sdX name which of course gets removed from the system after install thus reordering device names. When i remove all the HBA's from my system and just do the zfs mirror install using only 2 disk attached to the motherboard sata ports it enters proxmox just fine. but once i reinstall the HBA's it reorders everything.

Thought I should Add some more information into this posting as this problem is driving me crazy and I just cant spend so much time on this getting no where.

Hardware is a Supermicro X9srl-F motherboard with a Xeon 2650. 32GB Ram.
I have multiple LSI 9207-i8 HBA's, 1 GPU, USB card and 2 Intel NIC's

Proxmox 5.1, also experiences this with Proxmox 5.0

just trying to do a clean install of proxmox onto a ZFS mirror using 2 SSDs.

install from usb stick

after going through the install when proxmox is loading I'm hit with the error

cannot import 'rpool': no such pool avalible

Failed to import pool 'rpool'
Manually import the pool and exit

I am then able to manually do zpool import and use its long number identifier to import the pool and the system will successfully boot.

I am able to do edit ZFS_INITRD_PRE_MOUNTROOT_SLEEP as suggested in the Proxmox ZFS Tips and Tricks page however I still see that I'm getting a ZFS error on loading

Failed to start Mount ZFS filesystems
see 'systemctl status zfs-mount.service' for details


Just trying to find a way forward. I plan on passthrough the GPU and HBA's in this system to VMs and would like to try and prevent future problems when i do that as I suspect this all is caused by proxmox device naming scheme.

I'll also be creating some other ZFS pools to store VMs on.

Could you run

zpool import -f

inside your busy box. Please also check if the disks are present in /dev/
