Tools -> Diagnostics output attached.
Performed a SMART extended self-test (SMART Report attached) - Passed. A good surprise.

Success! So I have the server back up and it looks to be working as it was prior to the "issue" with one exception. I have errors on my 2nd cache drive (refer attached image). I think that drive may be on its way out??? I better look at how I can undertake some diagnostics on the drive to get a definitive answer as the drive is currently still under warranty.
Another thing I noticed was a new section on the Main tab called Historical Devices (refer attached image). Does anyone know what this is and should I just delete these OR do I need to do something with this detail?
I thought I'd quickly jot down the main steps I had to go through. Hopefully it might be useful to someone else?
- Mount the drive that is reporting as "Unmountable" (using the FAQ referenced in my previous post).
- Backup all data on the drive to another drive (I used rsync. e.g. rsync -aczvAXHS --progress /source /target Note: I found that the source directory was created in the target directory with all of it files and folder structure).
- Compare the backed up data with the original [optional] (I used rsync. e.g. rsync -n -avrc /source/ /target/source/).
- Unmount the drive (e.g. umount /source).
- Destroy data on the drive (my device was a SSD so I used blkdiscard /dev/sdX).
- Format the drive via the unRAID GUI.
- Copy all data back onto the cache drive (rsync -aczvAXHS --progress /target/source/ /mnt/cache).
- Compare the restored files [optional] (rsync -n -avrc /target/source/ /mnt/cache/).
- Reboot the unRAID server.

After a reboot of my unRAID server I noticed my cache drives (2 x 1TB SSDs mirrored) are showing as 'Unmountable: No File System'. The array also immediately performed a parity check which passed without errors.
I found a post (by sniggil) with a similar issue to my own. A response from JorbeB pointed to the below post which I have followed to mount the cache drives individually and backed up the data from both drives onto a drive in my Unassigned Devices. Given they were mirrored I'm not sure if this was absolutely necessary, but I don't want to loose anything if at all possible.
To backup the drives I mounted the 1st cache drive on /x and the 2nd on /y then used the following commands to create a copy of the data:
rsync -aczvAXHS --progress /x /mnt/disks/UD_TempStorage/cache_d1_backup
rsync -aczvAXHS --progress /y /mnt/disks/UD_TempStorage/cache_d2_backup
Note: I don't know enough about rsysnc to come up with the above commands - full disclosure, I found them online!
I now have no clue on the process I need to follow to get the system back up and running correctly and are seeking some guidance. I am thinking something like:
- Format the cache drives.
- Copy the data from my Unassigned Device drive to the newly formatted cache drive(s).
I have included the Tools -> Diagnostics output for completeness.
Any information would be greatly appreciated.
Thanks in advance.

I had a similar issue to @snowborder714 but my setup was working one day and then not the next. I found the same display behaviour was occurring with my issue which ended up being that I ran out of HD space. I removed some files and as soon as Shinobi could write to the disk again, the main image re-appeared. I thought I set Shinobi up to record continuously and to overwrite files when the disk became full.
Now to try and figure out why it is writing files with root:root (I'm sure it is something I have done, or not done!).

Sorry. To be clear does this file "timemachine.service" go in /etc/avahi or /etc/avahi/services?
Thanks to whomever found this "work-around"! I found this worked for me when I placed the timemachine.service file into the /etc/avahi/services directory. I hope this helps someone as it definitely helped me out.
P.S. It would be great if this was fixed at some point.
