Cannot acces subvolumes on ZFS storage

Dear all,

I had some issues updating to Proxmox 6 recently. So I installed again from scratch and copied the configuration files in /etc/pve. Proxmox is located on a 256 Mb SSD and data is organized on a raidz ZFS-pool containing 3 HDD.

In the web-GUI the virtual machines are shown, however proxmox cannot access the data of the ZFS-pool. Hence the conainers cannot access their HDD. I assume there is a mounting problem with the new proxmox install and the ZFS-Volume?

Result of zfs list:
