Hi all,

I have a late 2013 Mini with 1TB fusion drive, no big deals here but i am thinking of upgrading the HDD to either a sole SSD (with no fusion) or 2TB HDD (with fusion using the original SSD)

My question is........if i install a new HDD, will Yosemite configure the fusion automatically or will i have to play around with Terminal?

Thanks in advance for your help
 
You will need to re-configure the FD and reinstall the OS when one of the drives is replaced. I was prompted to create a FD automatically during the OS install when I installed the SSD in my Mini. I chose not to but the installer at the time (Mavericks) detected the possibility that it would work and offered to do it.
 
I recently upgraded a 2012 Mini Server by replacing one of the hard disks with a 512GB SSD. I too was prompted by DiskUtility during the OS X Recovery boot to automatically repair the Fusion drive (which I did initially try just to prove it worked). However, since I wanted to split the SSD into a Windows boot and OS X boot partition, I had to manually create the Fusion drive with just one partition of the SSD and the Hard Disk.

So ... yes, if you wish to use the entire SSD and Hard Disk as a Fusion drive, it will be created for you automatically during the setup and install process.
