Does running PVFS require a particular kernel or kernel version?
You can run the userspace PVFS servers and administration tools on every major GNU/Linux distribution out of the box, and we intend to keep it that way. However, the kernel module that allows client access to the PVFS system does depend on particular kernel versions because it builds against the running one (in the same manner as every other Linux module). The kernel dependent PVFS client support has been written for Linux kernel versions 2.4.19 (and greater) and 2.6.0 (and greater). At this time only Linux clients have this level of support.
