Hi, I've tried the mount, tunefs and df manuals, and don't know where to look next. I am trying to find out what device, in terms of /dev/ad0s1a and so on, is actually 'connected' to a label mounted file system. Here is my fstab (from PC-BSD, by the way): # more /etc/fstab # Device Mountpoint FStype Options Dump Pass /dev/label/rootfs0 / ufs rw,noatime 1 1 /dev/label/swap0 none swap sw 0 0 /dev/label/var0 /var ufs rw,noatime 1 1 /dev/label/usr0 /usr ufs rw,noatime 1 1 procfs /proc procfs rw 0 0 linprocfs /compat/linux/proc linprocfs rw 0 0 tmpfs /tmp tmpfs rw,mode=1777 0 0 I just wanted to know if there was a utility to tell me which actual device was mounted. I also tried camcontrol devlist and atacontrol list. The latter allowed me to determine that /dev/label/rootfs0 is ad2s1a based on the actual disk size and a process of elimination. Does anyone know a magic incantation to output this label->device mapping? Thanks Mark P.S. The latest FreeBSD 8 under PC-BSD is really quite good. My thanks to everyone involved. Picked up a copy at the freebsdmall with the guide. Excellent.
