I tried changing the port that OMV runs on, and when applying the setting I started getting this message:
Failed to execute command 'export LANG=C; monit summary 2>&1': /etc/monit/conf.d/openmediavault-filesystem.conf:30: Error: syntax error '"none"'
I don't think it's related to the port change, as it's complaining about file system monitors, but clearly something happened. I looked into the file, and traced the issue to several of my ZFS file systems that had a mountpoint of "none". They've been this way since I started using OMV a month ago, but whatever, I went ahead and gave them all proper mountpoints again. Unfortunately the error is still occurring. I tried this command to re-generate the config file:
sudo omv-mkconf monit
But no dice. Any advice?
