I was trying to use some Fusion-IO cards with Rockstor but was unsuccessful, basically you end up compiling the driver by using the kernel-devel package (I used kernel-ml-devel that I saw on another post) and the src.rpm for Centos7. The drivers are on the SanDisk/FusionIO site but I can easily share with anyone that cares (you DO NOT need fusionio cards to compile the driver, you also can specify a non-running kernel). I think the issue is very similar to others who are using 15.10 Ubuntu and newer kernels.
Generally you need the following packages:
yum install rsync tar gcc make kernel-devel-uname -rrpm-build
Then you run
rpmbuild --rebuild iomemory-vsl-<VSL-version>.src.rpm
TL;DR
Here is my error
