Well, i've been holding a Digital UNIX training course last week, and the one thing that really makes me jealous is what they call Logical Storage Manager (others call it LVM -- but they did have an inferior product called LVM previously, which is now abandoned). Sure, their filesystem is not as good as e.g. AIX's JFS, but they've got their volume management completely transparent and completely optional. You are free to also use the classic BSD partitions, and with their AdvFS, you can increase it by adding new volumes (you can even decrease it). Sure, UFS certainly doesn't allow us to increase a filesystem while being mounted, but adding a new volume in unmounted state, and using is as something like a different cylinder group range (or requiring the UFS to reside on a logical volume, and extend it) shouldn't be too hard. Too bad, i'm missing the time and the FS experience. -- 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. ;-)
