Booting error with zfs pool after Proxmox upgrade from 5.4 to 6.1

[de.dang]

Hi Team,

My installation is based a ZFS raid1. It used to work fine with Proxmox 5.4. However, I've recently upgraded up to 6.1. But it can't boot with new kernel (5.3.x) with error: "Can't import rpool..". I tried to follow this guide: https://pve.proxmox.com/wiki/ZFS:_Tips_and_Tricks#Grub_boot_ZFS_problem, but it does not help.
However, I can boot with older kernel: 4.15.x and GUI is upgraded up to 6.1 correctly.

Could you have any solution for this error.

Thanks,
De Dang

After upgrading to pve6, I only trouble in "Can't import rpool" in kernel 4.15.19 . But kernel 5.3.18 can boot normally.
