ha ha .. yeah. If the sysadm walks over to a machine an pour coffee in it then I guess it will fault all over the place. No appreciation for coffee I guess. however ... when it comes to storage I expect that a disk failure or hot swap will not cause a fault if and only if there still remains some other storage device that holds the bits in a redundant fashion. so .. disks can fail. That should be okay. even memory and processors can fail. within reason. > I do agree in principle, though.
