Neil, Thanks a lot, it raid did shutdown cleanly and restarted just fine, looks like JFS isn't quite mature enough yet. With that in mind fiddling with fdisk implies that one can subpartition a raid device, the FAQ doesn't seem to have any info, so before we go and tear down what we already have. Does the md driver support partitions in a meaningful/useful way? ----- Stephen C.
