5.4, ZFS mirror root: rescue boot can't find root

[Alexey Pavlyuts]

Hi All,

I found that riscue boot won't work. I found in in prodiction system an that was resolved via reinstall because of faster and everything was replicated to other nodes. Then I have reproduced on VM with proxmox inside proxmox.

So, 5.4 installed, properly updated. Let's imagine I have lost my GRUB or just use uefi from start. Trying of rescue boot lead to comression not supported in BIOS mode and just can't find rpool in UEFI mode.

Any suggestion?

Please try with the latest Proxmox VE ISO.

And aside, Proxmox VE 5 will be EoL, end of July 2020.

@Alwin , it does not work too. Just blink and go back, nor result. It I enter GRUB, it looks loke it see gpt partition and ZFS filesystem. However, if I try to ls or snose image to boot - it can't read, 'unsupported compression"

Even GRUB riscue on disk with full set of modules, build on the working host - does not work. Think, there no way to use UEFI at all.

It is quite dark prospects to ugrade to 6-th, due of every upgrade brings some risks )))
