Hey folks,

As an experiment I am converting a Caldera Linux
server to use FreeBSD 3.3.  The boot drive is now
UFS, but many of the disks on the system are still
ext2fs.

I have rebuilt my kernel and can now mount_ext2fs
and use the Linux disks nicely.  Reads, writes,
I've transferred tens of MB back and forth with
no problems between ext2fs land and UFS.

My problem arises when I try to export one of these
drives.  I do:

    mount_ext2fs /dev/da0s1 /d1

and my exports file is a one-liner that looks like

    /d1 -network 192.168.2

The system is quiet after these commands, and I can
still access /d1 locally.  If I step over to a client
machine (Linux) and mount this disk via NFS, things
are still fine.  The mounting in the client's fstab is
done with (noauto,soft,bg,retrans=1).

The bottom falls out when I try to do an ls -l of the
exported filesystem from the client.  The ls works, I
see the server filesystem contents on the client, and 
then the server's nfsd dies with a fatal error 12.

Each of these two services (NFS and ext2fs support)
seems to work well independently on this server.  Is
there a known problem with using them together?

I really appreciate any advice. I'm not yet subscribed
to this list, so email to my address below would be
great.

FreeBSD seems like a cool replacement for Caldera. In
a few days of work I've gotten most of the needed
services running, and that's without knowing anything
about BSD!
