(our AIX developer-on-call) Back me up or knock me down? } } AIX uses a journal file system, which is rather completely different from a } BSD unix file system. I haven't figured out any of the details. It may have } something in common with the Margo Seltzer log-structured file system, which } everyone seems to have lost interest in. } They call it their Journalled file system. I don't think that has anything to do with it's ability to enlarge a partition on the fly. Journalling, the keeping of an audit-trail of all disk writes, makes for a more secure filesystem that can be cleaned up more thoroughly and quickly after a crash. Back to the main question; I don't see any reason why the BSD file system couldn't be extended to allow for on-the-fly expansion of partitions. Toss in a pointer to the new space, when you feel like adding some, initialize it and continue on. Richard
