Hello,
I have a problem with my Open Media Vault zfs setup. I have installed a plain Debian 10 with ZFS as the root filesystem following the official openzfs guide: https://openzfs.github.io/open…er%20Root%20on%20ZFS.html
I then installed Open Media Vault from the official apt repos, added the omv-extras and installed the latest zfs plugin.
All installations completed without errors, however when I access the ZFS plugin on the webgui I get the following error message:
The configuration object 'conf.system.filesystem.mountpoint' is not unique. An object with the property 'dir' and value '/boot' already exists.
Error #0:
OMV\AssertException: The configuration object 'conf.system.filesystem.mountpoint' is not unique. An object with the property 'dir' and value '/boot' already exists. in /usr/share/php/openmediavault/config/database.inc:513

I already googeld the error message and found some older forum and github entrys from 2018 stating that this is an issue with the zfs-plugin and a newer version should fix this. But since I am on the latest version this doesn`t work for me.
If anyone knows a solution to this help would be much appreciated.
For more informations on my setup I have the following zfs datasets configured:
