Problem partitioning Fusioned MacBook Pro

[jamesjingyi]

Hi guys

So I have replaced the optical drive in my 2012 MBP 13" with a 1TB 7200rpm HDD. This now runs with my 128GB Samsung 840 Pro SSD and I fusioned them when setting up Yosemite. Now I have run into a problem. When I try to partition, I am met with:

Partition failed with the error:

A problem occurred while resizing Core Storage physical volume structures.

There is no error code for some reason as well.

Please help!

EDIT: For some reason I can partition in Boot Camp Fine

As you can see you can only add one partition to a fusion drive and that is on the HDD, in your case that will be the bootcamp partition.
