I believe a lot of what is in there either came out of the OMV installer or was generated later based on the initial configuration.
I think a reinstall is the way to go. Try doing it this way first before starting over from scratch with the iso installer:
Codesudo apt-get install --reinstall openmediavault
wow never thought that would work 
till i "somehow" fd up a couple of folders... ran your code and 10 seconds later poof all better...Thx
