Failed to boot cannot import rpool after update

[the_hunk]

Hi. After the upgrade, the server can not boot. Can I recover it or get the data?

Loading, please wait...

Command: /sbin/zpool import -N rpool
Message: cannot import 'rpool': no such pool available
Error: 1

No pool imported. Manually import the root pool
at the command prompt and then exit.
Hint: Tyr: zpool import -R /root -N rpool

BusyBox v1.22.1 ....
/ #


# zpool import
no pools available to import

# blkid -l -t TYPE=zfs_member
nothing
# blkid
The partitions with UUID (sd{a,b}{1,2,9})

if I run
# zpool import -d /dev/disk/by-id rpool -R /root
I can find my vm (.qcow2) in /root/var/lib/vz/images/

After reboot the same problem!
Please, help.

Sorry. I gave the wrong information.
After carefully reading the forum, I found a solution.
After run "# zpool import -d /dev/disk/by-id rpool -R /root" be sure to print "exit" to boot
Then again, I get in BusyBox:
Error: Failed to mount root filesystem ´rpool/ROOT/pve-1´
I run:
# mount -o zfsutil -t zfs rpool/ROOT/pve-1 /root
after exit the normal boot sequence goes on and system comes up.
Question is how to solve this so that the system comes up without manual investigation?

I tried this solution: https://forum.proxmox.com/threads/p...s-failed-since-update-no-pool-imported.24297/
But this not work for me.

I think the correct command in your case would be "zpool import -d /dev/disk/by-id -R /root -N rpool" followed by exit
could you also post the output of "zpool import -d /dev" (in the initramfs rescue shell)?

Thanks for the answer. I'll try at the weekend. Now there is no way to restart the server.
