Having trouble mounting encrypted disk (ZFS) on Ubuntu

cn flag

I have a new SSD to backup photos. I installed Ubuntu 21.10, with ZFS and encrypted. Everything worked well and I decided to backup some photos.

Now, I wanted to boot with my old encrypted disk (Ubuntu 21.04). Nautilus can see the new Disk, but I get "incorrect passphrase".

I am trying to boot from the new disk, and I can not... I get:

error: unknown filesystem.
Entering rescue mode...
grub rescue>_

When I run sudo fdisk -l I see:

....

And then I am lost... I don´t know what is the next step to access to the Disk...

What can I try to fix this or to access to the disk?

Thanks in advance!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
