Well !! My patch does not have anything hardcoded to 4000. Depends on how many minor bits. But we have to put a hardlimit somewhere .. > Just imagine multipathing today's 4000 disks. Fortunately, the multipath solution Mike Anderson & Patrick Mansfield working on, colapses all the disks you see thro multiple paths into number of realdisks (4000). So you don't really need extra devices to support multipathing. Thanks, Badari
