You'd like LVM2 on Linux. You assign your physical disk partitions to a physical volume group (conceptually like an SMS volume group). You can then divvy up the space in that group into various sized logical volumes. This is then initialized with a filesystem with mkfs (equivalent to ICKDSF, I guess). If the filesystem runs out of space, and you used the proper type of filesystem (there are many), you simply expand the size of the logical volume into unused space in the group. You then resize the filesystem. If you used ext4 or btrfs, I think you can do this while it is in use. If you used ext3, I think you need to unmount it (take it "offline") to resize it. If you're out of space in the volume group, buy another disk and initialize it into the physical volume group, then expand. logical volume space does not need to be physically contiguous. > -- John McKown Maranatha! <>< ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
