Gvinum RAID5 volume don't work after a simple reboot

[Olivier Cochard]

I've changed the procedure... but no changes: the Raid Volume refuse to
works after the reboot.

Here is the new procedure I've used:

1. initializing hard drive:
/bin/dd if=/dev/zero of=/dev/ad0 bs=1k count=20");
/sbin/fdisk -I -b /boot/mbr ad0
/sbin/bsdlabel -w ad0 auto

2. Generating config file:
$ cat /var/etc/raid.conf
drive disk_ad1 device /dev/ad1a
drive disk_ad2 device /dev/ad2a
drive disk_ad3 device /dev/ad3a
volume raid5
plex org raid5 256k
sd length 102M drive disk_ad1
sd length 102M drive disk_ad2
sd length 102M drive disk_ad3

3. Create a filesystem on it:
/sbin/newfs -U /dev/gvinum/raid5

4. Mount it and put a file without problem

5. Reboot... Same problem.
