@fabian, thank you for the packages! Please find the boot log attached below and tell me if you need anything else!

that seems rather strange, it seems to fail when reading the root block pointer. could you do the following:
re-run the "ls" in grub to get the current DVA values, the following line directly before the checksum verification fails:

fs/zfs/zfs.c:301: zio_read_data: bp DVA: 8 13005bb90 / 8 9418 / 8 188001ac0

now, without importing the pool, reboot in the installer rescue shell and run the following (replacing all three DVA offsets with the numbers obtained in Grub):

for offset in 13005bb90 9418 188001ac0; do zdb -e -R rpool 0:$(python3 -c "print(hex(0x$offset << 9))"):800 > out_$offset; done

save the resulting out_* files and post them here together with the new logs.

Hi all!
I have the same issue with a HP DL160 G9. There's no solution yet?

Hi all
I have the same issue on Hetzner AX160-NVMe server with sata-ssd mirror zfs root. Installed Proxmox 5.2, than upgraded to 5.3 and after reboot get - no such device, unknown filesystem.

It happened to me too (third time...) on my testserver, HP DL120 G7.

This one is running on 2 x 4TB drives.
Another one runs on smaller < 2Tb drives, no problems yet.

Any hint on what is the cause? Or how to create a boot USB to get it on its feet again?
