Dear,

I have test out on a brand new host with a new installation (3 times) of Proxmox VE 5 ZFS (OVH-Image) and then I have make an upgrade with documention on wiki to Proxmox VE 6 and direct after reboot the server not starts about they cant find the ZFS rpool!

So I have testet 3 times and by the last one, I have installed from same, then I have make a deinstallation of corosyn and proxmox-ve and then an update on from debian 9 to debian 10. I have then make an restart and all was fine. Then I have make a new installation of proxmox-ve 6 and after the reboot the host hangs again, why rpool not found. The last kernel information:

Linux (none) 5.0.18-1-pve #1 SMP PVE 5.0.18-1 Wed, 24 Jul 2019 ... x86_64 GNU/Linux

Hardware: Intel CPU with 8/16 c/t and 128 MB RAM and 2 x 2 TB NVMe-SSD

It looks like a havy bug
 
corosync and proxmox-ve are not involved at all in the early boot, so this makes no sense. have you tried with our installer instead of the one provided by OVH? at what stage do you get this error message? initramfs? bootloader? ...?
 
Dear;

the problem is a timeout - I found an other forum entry about this problem and the resolution of this helps:

The resolution (described in wiki as tips and tricks) is so simple, but needs 2 working days to find out where I must search to find this resolution, why the upgrade process self no automaticly make the correct entries to fix this automaticly!

You find the resolution under: https://pve.proxmox.com/wiki/ZFS:_Tips_and_Tricks - and their under:
Boot fails and goes into busybox
