 one question; Why does vinum not start at system startup ?

 At the bottom of my rc.conf file, I have added:
 start_vinum=YES

 When I reboot the system, all I see in dmesg is:
 vinum: no drives found


 I can start it manualy:

 server# vinum create config1
 2 drives:
 D a State: up   /dev/ad1s1c A: 39166/39266 MB (99%)
 D b State: up   /dev/ad2s1c A: 229/329 MB (69%)

This is a bug in Vinum.  It shouldn't let you start it manually.

From the man page:

DRIVE LAYOUT CONSIDERATIONS
 vinum drives are currently BSD disk partitions.  They must be of type
 vinum in order to avoid overwriting data used for other purposes.  Use
 disklabel -e to edit a partition type definition.  The following display
 shows a typical partition layout as shown by disklabel(8):

 8 partitions:
 #size   offsetfstype   [fsize bsize bps/cpg]
   a:81920   3440644.2BSD0 0 0   # (Cyl.  240*- 297*)
   b:   26214481920  swap# (Cyl.   57*- 240*)
   c:  42267250unused0 0 # (Cyl.0 - 2955*)
   e:8192004.2BSD0 0 0   # (Cyl.0 - 57*)
   f:  190   4259844.2BSD0 0 0   # (Cyl.  297*- 1626*)
   g:  1900741  2325984 vinum0 0 0   # (Cyl. 1626*- 2955*)

 In this example, partition ``g'' may be used as a vinum partition.  Par-
 titions ``a'', ``e'' and ``f'' may be used as UFS file systems or ccd
 partitions.  Partition ``b'' is a swap partition, and partition ``c''
 represents the whole disk and should not be used for any other purpose.

 The vinum utility uses the first 265 sectors on each partition for con-
 figuration information, so the maximum size of a subdisk is 265 sectors
 smaller than the drive.

Choose a different partition, and reset partition c to unused.

It feelt really ackward.  I had overseen the 'setupstate' flag and it
solved the problem partialy for me :-)

Yes, I also oversaw this in the man pages. I figured it out last night
with trial'n'error, Now im using partition 'e:'.


Now vinum works perfectly for me. I appreciate your help, thanks :-) 

I find vinums man pages is very good, but maybe the dd/fdisk/disklabel
sections are a bit vague and confusing for newcomers. What do you think?
