Running 4.4 (upgrading soon) and have a few ZFS pools in the box. One contains the VMs and storage. Rebooted for the first time in 6 months and saw the error that "Volume Group 'PVE' not found" and it dumped me into a BusyBox shell.

I rebooted a few times and eventually proxmox booted but web UI does not work and no ZFS pools are mounted. Did some searching and tried a few solutions, no luck with any of them so far.

Tried editing the grub config with the following as suggested elsewhere
GRUB_CMDLINE_LINUX_DEFAULT="quiet rootdelay=10"
GRUB_CMDLINE_LINUX="scsi_mod.scan=sync"
GRUB_PRELOAD_MODULES="lvm"

No luck.

Tried editing lvm.conf to disable filtering also no luck.

Recently I enabled snapshots for my pools, smartctl, monit, and zfs scrubbing. I was having issues with some LXC stopping so I rebooted the entire box through IMPI knowing they would boot powered down. Was planning on upgrading to Proxmox 5 then. Since Proxmox never loaded I've been trying to get it back online and working again before I upgrade.

Anyone know what might be going on here?

Just tried this
Code:
/etc/default/zfs

ZFS_INITRD_PRE_MOUNTROOT_SLEEP='0'  we changed it to 4
update-initramfs -u
reboot
with no luck either
My ZFS list returns no datasets, the mount points are all there but with nothing mounted. And I can zpool import poolname but they dissipear after reboot and proxmox webGUI still doesnt work.

I upgraded and everything is working now with a fresh install but this message still comes up in the terminal after proxmox has loaded.

Out of curiosity are you using ZFS on root/system disk? If not, I was thinking you can try exporting and then importing the pool. Make sure to do full backup of your VM's/VM data just in case.
