Alright so I have my setup with around 30 fiber connected machines to this Xsan. This Xsan is NOT sharing over AFP, fiber only. I have spotlight enabled. Nobody is on either AD or OD as there is no need its just dumb permissions in this environment so everything is POSIX on the SAN. This week one of my users who does not have a fiber connection learned that he could connect to one of the Macs that does have a fiber connection then use their credentials to share files. At that point they then mounted the SAN share on their desktop over AFP. Essentially what appears to be twice but could be coincidental, shortly after that user mounted the SAN over AFP through a fiber connected client the volume became unstable and running cvfsck was required as well as rebooting the systems. Obviously I have since disabled file sharing on all the fiber hosts but wanted to see if this users actions could cause such issues or is it that my file system is just getting wonky and I should probably start looking into rebuilding?
