I've once noticed problems of this kind if the UFS in questions has device nodes that are currently open, regardless of whether the pathname on the mounted device or any other UFS has been used to open this descriptor. E.g., if your JAZ disk has a /dev/console on it, and /dev/console is currently open (which it usually is), you can't umount it without also setting MNT_FORCE (aka. ``umount -f''). Needless to say, with DEVFS, you no longer need to have device nodes on your UFS at all. :-) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
