Hi, made a pretty nice setup with OMV 5 and everything is working after 2 days of trial and error.
Proxmox Kernel seems to be must for ZFS (Backports hasn't recognized my SATA Controller) and for docker I had to remove the apparmor package
(else all containers restarting continously).
As stated, all working as in OMV 4, only the autoshutdown plugin does not allow to exclude process supervision as it was possible in version 4 with
SYSLOG shows the following errors several times
The autoshutdown plugin itself is then running in FAKE mode without this option being set in the menu before.
