I know the unionfilesystem plugin moved from using mhddfs to mergerfs in OMV 3. Somehow in the course of my updating, references to mhddfs were left in my configuration, so accessing "Storage / File Systems" in the GUI results in the error "No filesystem backend exists for 'mhddfs'." What's the best way to fix this with minimal loss to my current configuration? Thanks.

Burn this to a disc or USB drive and boot from it: GPartEd Live CD

Use GPartEd and resize your SSD partition to make it smaller: GPartEd Manual - Resizing a Partition

Then use GPartEd again to make a new partition from the unused space: GPartEd Manual - Creating a New Partition

Finally, reboot your server and pray that it works!
