vinum problems

[ejc]

I'm getting kernel panics related to vinum.  I've been running -devel
for a couple of months now, updating every couple of days.  Currently
I've got 1.11.0-DEVELOPMENT as of yesterday afternoon (2007-07-25)
installed.
I follow the make buildworld, buildkernel, installkernel,
installworld, upgrade process detailing in UPDATING
FS layout is:
-bash-3.2$ df -h

procfs        4.0K   4.0K     0B   100%    /proc
with my vinum device on /usr/space.  I have ad0 and ad1 to use for vinum.

I nuked the vinum config on the drives using dd, and rand fdisk and
disklabel.  I also nuked /dev/vinum.
bash-3.2# vinum start
loads vinum.ko and starts vinum just fine, but then funky things start
happening to the other filesystems.

With more of the dscheck... stuff in dmesg and this gem:

spec_getpages:(#da/0x20005) I/O read failure: (error=22) bp 0xc11bfa00 vp 0
              size: 65536, resid: 65536, a_count: 65536, valid: 0x0
              nread: 0, reqpage: 0, pindex: 0, pcount: 16
When I try to edit a file that suffers from the 'Bad file descriptor' error.

Eventually the box will panic, though it's more resistant to that than
1.9 from a couple of days ago was.  That would panic the first time I
tried to edit or access one of these files.
Unload vinum.ko

bash-3.2# kldunload vinum
bash: /sbin/kldunload: Input/output error
bash-3.2# vinum stop
vinum unloaded
but the problems with other files persist.

Any ideas?

Thanks,
Eric
