I was helping a friend as he wanted to add a partition to a new install, = ie he did (effectively) this.. truncate -s 10m /tmp/test mdconfig -a -t vnode -f /tmp/test fdisk -BI /dev/md0 bsdlabel -w /dev/md0s1 bsdlabel -e /dev/md0s1 <change a: to> a: 2048 16 4.2BSD 0 0 0=20 newfs /dev/md0s1a mkdir /mnt/test mount /dev/md0s1a /mnt/test bsdlabel -e /dev/md0s1 Then you get.. "bsdlabel: Class not found" Note that just touching the file bsdlabel is using is enough to cause it = to generate that error. I tried the same steps on a 7.x system and it worked fine. ktrace shows ... 90200 bsdlabel CALL ioctl(0x4,DIOCGMEDIASIZE,0x7fffffffe430) 90200 bsdlabel RET ioctl 0 90200 bsdlabel CALL ioctl(0x4,DIOCGSECTORSIZE,0x7fffffffe434) 90200 bsdlabel RET ioctl 0 90200 bsdlabel CALL ioctl(0x4,DIOCGFWSECTORS,0x7fffffffe454) 90200 bsdlabel RET ioctl 0 90200 bsdlabel CALL ioctl(0x4,DIOCGFWHEADS,0x7fffffffe454) 90200 bsdlabel RET ioctl 0 90200 bsdlabel CALL close(0x4) 90200 = bsdlabel RET close 0 90200 bsdlabel CALL close(0x3) 90200 bsdlabel RET close 0 90200 bsdlabel CALL open(0x800c04040,O_RDWR,<unused>0x26ec) 90200 bsdlabel NAMI "/dev/md0s1" 90200 bsdlabel RET open -1 errno 1 Operation not permitted 90200 bsdlabel CALL open(0x800651b5f,O_RDONLY,<unused>0) 90200 bsdlabel NAMI "/dev/geom.ctl" 90200 bsdlabel RET open 3 90200 bsdlabel CALL ioctl(0x3,GEOM_CTL,0x800c06040) 90200 bsdlabel RET = ioctl 0 90200 bsdlabel CALL close(0x3) Note that my friend tried it on real hardware and said that after he = rebooted it appeared(!) -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
