So I know this is an isolated issue.

I know there are few Mac hoarders.

I know there are alternates like MergerFS and drive Pool. None are macOS native.

I just want to pull my drives together.

Now MHDDFS use to work before Catalina pretty well. With macOS Catalina came the end of 32 bit code.

MHDDFS isn’t 32bit to my knowledge and osxFuse is up until 3.9.

MacPorts is not 32 bit. When running port install is stops an breaks when pulling down osxFuse and other dependencies.

Even installing the latest, MacPorts still wants to pull down 3.8.3. I’ve edited the port file to skip that an now 2 minor dependencies unrelated to MHDDFS and osxFuse (their inclusion I believe is to build the port).

So running MHDDFS with the latest OSXFuse I get an error 255 that the filesystem is unavailable. Almost as if mhddfs doesn’t see the osxFuse install and needs its own separate instance in order to function.

Anyone (I mean anyone) else run into this?

Wanted to give it one more chance to have a native pooling option before resorting to using Fusion and raw disk mapping and using whichever of the previous solutions in a VM.

For this who don’t know, raw disk mapping allows one to use any formatted disk as a native drive in the first OS without wiping existing data.

I can take a Mac Mac formatted disk with data, map it, use it like an NTFS drive in the Guest and make changes. Once I shutdown the Guest the disks become available to macOS with the changes done from the guest OS.

Down side is that the disks are not available to macOS while in use from the guest.

MHDDFS allowed me to mount the drives in a VM for balancing via mergerFS and have the virtual volume available to Plex.
