You need to start Vinum before you can mount the volumes. I haven't committed a modification to that one, but you could try this: /etc/rc: After the text: # Configure ccd devices. if [ -f /etc/ccd.conf ]; then ccdconfig -C fi Add: if [ -f /etc/vinumconf ]; then /etc/vinumconf fi /etc/vinumconf looks like: #!/bin/sh # Mount a temporary /tmp to be able to load the LKM # Care! At this point we don't *have* a swap mount_mfs /dev/sd0s1b /mnt modload -o /mnt/foo /lkm/vinum_mod.o /sbin/vinum read /dev/sd2h /sbin/umount /mnt The /dev/sd0s1b is the name of the swap partition. It's just used so that MFS will create a file system. It could cause problems with small memory (I'd guess < 8MB).
