Hello misc,

  I've  been  booting my system from RAIDframe partitions for a long while.
Small  partition  for kernel(s), raidctl -A root raid0 - and I have root on
raid0a and swap on raid0b.
  But with 4.2 I'm getting "swapmount: no device" error from the kernel and
"savecore:  no  core  dump  (no  dumpdev)" later. However, root is still on
raid0a (but no swap).

  I've  tried "config bsd root on raid0a swap on raid0b dumps on wd0b" in a
kernel config, but got:

# config GENERIC.MP.RAID
../../../../arch/i386/conf/GENERIC.RAID:45: bsd: can't make root device from `raid0a'
../../../../arch/i386/conf/GENERIC.RAID:45: bsd: can't make swap device from `raid0b'
GENERIC.MP.RAID has no configurations!
*** Stop.

  I  have  an idea about a (pretty nasty) workaround, but is there a way to
make it "right"?

  BTW, "config bsd root on wd0a swap on wd0b dumps on wd0b and wd1b" should
be ok (according to the main page), but config doesn't like "and wd1b".

I just set up RAIDframe for the first time using 4.2 following the 
instructions located here:

    http://www.eclectica.ca/howto/openbsd-software-raid-howto.php

When I booted into the raided system, I noticed the following output:

    <snip>

which shows both the "swapmount: no device" and "savecore: no core dump 
(no dumpdev)" issues Boris reported.

Here are my disklabel and fstab


   # disklabel raid0 | tail -4
   #                size           offset  fstype [fsize bsize  cpg]

     b:          1048576         15683584    swap                   
     c:         16732160                0  unused      0     0     

   # cat 
/etc/fstab                                                              
   /dev/raid0a / ffs rw 1 1


Note: prior to booting in the raid set, I'd get : "root on sd0a swap on 
sd0b dump on sd0b"

Thanks,
Kent
