I recently updated my mac pro from Mavericks to Yosemite. Afterwords my ZFS raid 5 stopped working (was not seen by the system). Please read this entire guide and the warnings before trying to fix your issue! Also please backup your data before trying to fix your zfs raid.
To fix this I did the following:
Downloaded ZFS 1.2.7 from HERE
Next i upgraded my zpool from Terminal
zpool upgrade data (NOTE: data is the name of my zpool change this to your zpool’s name.)
After all this i noticed the mount point for my zpool was not set so i set the mount point.
zfs set mountpoint=/Volumes/data data
To verify the above command worked i displayed the mount points
After this i saw that it was not mounted so to mount the pool you do
After this I was able to use my raid 5 drive.

For months now i have been fighting the rats nest in the top of the closet in my office were i keep all my network gear. There were old cables wire tied to more old cables 12-18 inches thick and power cables were always falling down. It was a nightmare whenever i needed to move a cable or add a new device.
Today I pulled every wire and cable out of the closed. I started by wall mounting my network switch, and power strips. I cable tied the wires come into my patch panel so they were not dangling loose and the same for the wires going to my NVR (network video recorder – for my security camera system).
Next I went around the house and tested each network jack in various room and labeled them on both the jacks and the patch panel. One positive of that end ever i found one jack misfired which I am sure was causing collisions and other network issues.
After all of that was done and several trips to Fry’s I was able to neatly route all my cables, label them…
I should have taken a before picture but never the less here is the results!
