@maikel : Not the same issue mate, this is the first time ever i install zfsonlinux and my packages are for fedora 23.
I used the new packages available through github (specific for fedora 23), the module could not build for whathever reason, seems that it is looking for files i do not have since a genius decided that when you update the system why not update the kernel itself #yolo.
So i'm screwed, i have absolutly zero knowledge in kernel so i have no idea how to get those files back (something like kernel-header, sources etc) and i have to boot on my previous kernel otherwise i cannot launch my qemu vm which uses vfio.

@chris : already did, still waiting for an answer...

Hey all,

I ran in the same problem. I removed the ZFS repo of ZFS itself. I installed the Fedora version, after that the ZFS pool was unable to be mounted (something with dependencies of features). 

I then proceeded to remove everything of ZFS on my system and installed again the ZFS repository. This turned out to be the winning move. Why? I don't know, but the ZFS packages of the repository compiles something. So, my bet it does something to the kernel and with the upgrade of Fedora 23 it got broken.

Installed packages ATM:
libnvpair1.x86_64                     0.6.5.4-1.fc23            @zfs           
libuutil1.x86_64                      0.6.5.4-1.fc23            @zfs           
libzfs2.x86_64                        0.6.5.4-1.fc23            @zfs           
libzpool2.x86_64                      0.6.5.4-1.fc23            @zfs           
spl.x86_64                            0.6.5.4-1.fc23            @zfs

I suggest filling an issue ticket with upstream, or ask on their list or forum.
