SUMMARY: Using LUNs on AdvFS???

Well, it seems the answer is yes and no.

Yes, the kernel is able to handle the devices.
No, dxadvfs cannot handle them (coming up in 4.0, I've heard), but the
commandline utilities can.

But what I ran into seems to be a bug, probably in the kernel, when
starting up advfs. After a reboot my system, showfdmn says:
              Id Date Created LogPgs Domain Name
3208709a.00002126 Wed Aug 7 13:31:54 1996 512 kitty

  Vol 512-Blks Free % Used Cmode Rblks Wblks Vol Name
   2 3657728 675504 82% on 128 128 /dev/rz0g
   3L 7880704 1503184 81% on 128 128 /dev/rz0g
      ---------- ---------- ------
        11538432 2178688 81%

'Vol Name' of 'Vol 2' SHOULD be /dev/rzb0g, i.e. LUN 1 !!!
 
I think the problem is one of the following: (or a combination)
1) The Log is not on Volume 1 (It works ok on another machine where the
   log is on volume 1.
2) The Log is not on the lowest numbered volume
3) There is no volume 1

The biggest problem here is that I've lost 'control' of the volumes in
the domain. addvol will nicely add new volumes, but rmvol removes volumes
at random, leaving /etc/fdmns in a completely inconsistent state!

I run 3.2D-1 (rev 41), if anybody knows about patches I'd love to hear
about it!
