Hi Anand, is there any reason to put this kind of logic in the kernel space ? I think that it could be more simply to create a daemon which checks the disks and when needed it starts a replace... The pool policy could be more sophisticated: some filesystem could require a "dedicated" pool (for example because the disks are in the same enclosure); in other case a global pool may be more useful. Another feature of this daemon could be to add a disk when the disk space is too low, or to start a balance when there is no space to allocate further chunk..... Of course all these logic could be implemented in kernel space, but I think that we should avoid that when possible. Moreover in user space the logging is more easy.... Only my 2¢...
