@exelan and @Flyer
I have replied to @exelan original thread on the issue ‘yum upgrade -y’ and the missing files. Pretty sure the Rockstor package @exelan now has installed is really really ancient. I think this is due to that command being executed prior to choosing an update channel and consequently force (via -y) downgrading to a version that existed prior to this update channel mechanism.
We could continue the discussion / diagnostic over there as this thread appears to be unrelated and the linked thread has far more detail; linking:
Hope that helps.
