They must be of type vinum in order to avoid overwriting data used for other purposes. Use disklabel -e to edit a partition type definition. > The /stand/sysinstall only allows me to create a file system or swap > partition.

In fact, it now is: fstype describes the purpose of the partition. The example shows all currently used partition types. For UFS file systems and ccd partitions, use type 4.2BSD. For Vinum drives, use type vinum. Other common types are unused and swap. By conven- tion, partition c represents the entire slice and should be of type unused, though disklabel does not enforce this con- vention. disklabel also knows about a number of other parti- tion types, none of which are in current use. See the defi- nitions starting with FS_UNUSED in /usr/include/sys/disklabel.h for more details. Specifically, you need to create a new partition in the list: # size offset fstype [fsize bsize bps/cpg] b: 393216 0 swap # (Cyl. 0 - 682*) c: 8380080 0 unused 0 0 # (Cyl. 0 - 14548*) h: 7986864 393216 vinum 0 0 # (Cyl. 0 - 14548*) The offset value is the size + offset of the b partition (in other words, it starts immediately after the b partition). The size is the size of the rest of the disk, i.e the size of the c partition - the size of the b partition. Greg -- When replying to this message, please copy the original recipients.
