@NuclearFury Welcome to the Rockstor community.
I’d like to at least start with this one if I may, also if you are using the system without having upgraded to the improved 4.12 kernel that comes with either update channel then you don’t have all the interim improvements within the kernel on the btrfs, these could help with your stated and very reasonable:
So getting to the much improved 4.12, via either update channel subscription should help.
What is the output of:
yum info rockstor
Also you samba issues could be related to an interrupted update, see the following thread:
Could the 2.5" 250GB OS drive be flaky at all. Ie. try running a short and then a long smart test via the instructions as: S.M.A.R.T just in case.
Also an precis of your systems current state / function would be good.
Hope that helps.
