ZFS with Proxmox and OMV

Hi,

I've managed to get OMV (usul) and Proxmox (6.) running side by side using this as a guide:

• https://weekly-geekly.github.io/articles/328048/index.html

I have 4 WD Red 4TB drives in the PC, and when I installed proxmox I selected RAID10 as the installation option. This all worked fine, and it created the rpool (zpool status below). I cannot get OMV to recognize the existing pool (rpool). Is there a way I can configure this by hand? The GUI doesn't seem to want anything for ZFS other than empty disks. I'd really like to manage the datasets and snapshots on ZFS in OMV.

Of note: I was not able to install openmediavault-omvextrasorg package. I did edit openmediaault-zfs_5.0.1_amd64.deb to not list this as a dependency. It didn't seem necessary in this case (but I could be wrong).

# zpool status
  pool: rpool
 state: ONLINE
  scan: none requested
config:


        NAME                                                STATE     READ WRITE CKSUM
        rpool                                               ONLINE       0     0     0

FYI, here are the errors when Installing openmediavault omvextrasorg.

#dpkg -i openmediavault-omvextrasorg_latest_all5.deb

I rebuilt the pkg moving the problem gpg file (since it's already on my system from proxmox). The right way would be to have the script check for the file and skip it if it's there, but I wanted to see if it'd install.

cd /usr/src
wget https://github.com/OpenMediaVa…rasorg/archive/master.zip
unzip master.zip
cd openmediavault-omvextrasorg-master/etc/apt/trusted.gpg.d/

I still can't seem to add anything to the existing ZFS pool. Is there a way this could be manually added to the database?

As an additional test, I created a proxmox guest OS with 5 drives. Installed proxmox to the first, and replicated everything. Decided to try OMV being in control of the pool instead of proxmox. It appears that OMV cannot handle raid10. If this isn't true, can anyone comment on how to make that happen?

Ideally I'd just like OMV to see the pool (rpool from proxmox), and then create whatever datasets I need, and let proxmox handle the zfs volumes for virtual machines. Anyone have any pointers?

Thanks!
