OK, I understand the layout of the minor number according to sys/disklabel.h, but what's with the numbering scheme here? freebsd# ls -l /dev/ad0* crw-r----- 2 root operator 116, 0x00010002 Nov 17 2002 /dev/ad0 crw-r----- 2 root operator 116, 0 Nov 17 2002 /dev/ad0a crw-r----- 2 root operator 116, 1 Nov 17 2002 /dev/ad0b crw-r----- 2 root operator 116, 2 Nov 17 2002 /dev/ad0c crw-r----- 2 root operator 116, 3 Nov 17 2002 /dev/ad0d crw-r----- 2 root operator 116, 4 Nov 17 2002 /dev/ad0e crw-r----- 2 root operator 116, 5 Nov 17 2002 /dev/ad0f crw-r----- 2 root operator 116, 6 Nov 17 2002 /dev/ad0g crw-r----- 2 root operator 116, 7 Nov 17 2002 /dev/ad0h crw-r----- 2 root operator 116, 0x00020002 Nov 17 2002 /dev/ad0s1 crw-r----- 2 root operator 116, 0x00020000 Nov 17 2002 /dev/ad0s1a crw-r----- 2 root operator 116, 0x00020001 Nov 17 2002 /dev/ad0s1b crw-r----- 2 root operator 116, 0x00020002 Nov 17 2002 /dev/ad0s1c crw-r----- 2 root operator 116, 0x00020003 Nov 17 2002 /dev/ad0s1d crw-r----- 2 root operator 116, 0x00020004 Nov 17 2002 /dev/ad0s1e crw-r----- 2 root operator 116, 0x00020005 Nov 17 2002 /dev/ad0s1f crw-r----- 2 root operator 116, 0x00020006 Nov 17 2002 /dev/ad0s1g crw-r----- 2 root operator 116, 0x00020007 Nov 17 2002 /dev/ad0s1h crw-r----- 2 root operator 116, 0x00030002 Nov 17 2002 /dev/ad0s2 crw-r----- 2 root operator 116, 0x00040002 Nov 17 2002 /dev/ad0s3 crw-r----- 2 root operator 116, 0x00050002 Nov 17 2002 /dev/ad0s4 Why is the whole disk slice 1, but partitions within it are slice 0? Why isn't the whole disk slice 0 and slice 1 is ... slice 1 (ad0s1)? What makes ad0s2 be partition 3? Am I reading this right? Sam
