You don't need to reformat, but between 2.0R and 2.0.5R, the slice approach has been introduced. This means that FreeBSD learnt how to handle fdisk tables, but had the consequence that the device naming has changed, and some of the checks are now more strict. So, your DOS and FreeBSD slice (slice == fdisk partition, in order to distinguish them from the historic meaning of a Unix partition) will have a slice name of its own each, e.g. /dev/wd0s1 and /dev/wd0s2 (derived from the fdisk table info). For the BSD slice, you need a disklabel that is now only allowed to reference partitions inside the BSD slice, and the figures are relative to the beginning of the slice. Hence, the `c' partition (e.g. /dev/wd0s1c) _must_ start at offset 0 and _must_ cover exactly the amount of blocks as is told by the fdisk table. The `d' partition is no longer `magic', and should be removed from you label to avoid confusion. (It will probably be rejected by the kernel anyway since it references outside the BSD slice.) The remaining partitions must be adjusted in the label to become slice-relative. -- 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. ;-)
