Hi Everyone,

I'm still relatively new to FreeBSD so please excuse the newbieness :-)

Actually, I'll break this up into a few questions.

1) Is it normal for a vinum volume, when un-mounted, to cause a reboot?
   We have a volume, /users, composed of da1 and da4 (for about 800G of
space), 
   that when the device is unmounted, the system reboots itself.

2) Using setquota (on the above volume) causes the system (rather access to
/users)
   to grind to a halt (with no error messages in dmesg or
/var/log/messages).  The
   only way to get out of this is a reboot of the system, which forces a
fsck :-(

   The symptom pops up after adding a quota for myself, and then moving on
to another
   user.

3) I'll describe the hardware setup below, but we are using a IBM eSeries
server with
   a Qlogic FC-AL HBA to connect to a raid to store data.  Using sysctl or
sysinstall,
   after the (above) vinum volume has been mounted, causes a kernel panic
and a reboot.

   Anybody else have experience with a QLogic ISP 2200 HBA?

Our setup.

IBM eSeries xServer 340 (formerly the Netfinity 4500R)
  * 2 1.0GHz processors (kernel is in uni-processor mode until I figure out
what else
    the kernel config needs (simply defining SMP and APIC_IO hangs the
system on boot)).
  * 2 Intel EtherExpress Pro/100 (fxp) cards
  * 1 AMD ethernet card (pcn)
  * 1 Qlogic ISP 2200 (isp) HBA
  * 1.1GB of memory
  * 1 9GB system disk

This box is just one big monster NFS server for about 250 clients right now
(SGI IRIX,
IBM AIX, and RedHat Linux).

We've set the following sysctl.conf variables

kern.maxfiles=150000
vfs.vmiodirenable=1

Below is our kernel config

Once I get a crash dump (of the running kernel below) I'll send that on.  I
only have 
one or two windows of opportunity/week to make this happen since this is a
production
machine.

Many thanks in advance,
	Ryan
