System crash with combination of lofi encryption + ZFS + NFS
Dear Illumos team,
I have a fairly complicated issue, but I manage to reliably crash the system with it.
I have an openindiana system that I want to use as a file server, I have no previous experience with Solaris or Illumos - please bear with me :)
I want to test a raidz1 ZFS pool over 5 disks - one of which has not arrived yet. To play around a bit with ZFS already, I created a zpool over the 4 existing disks and a sparse file, which I subsequently offlined.
To make matters more interesting, the 4 disks have been loopbacked with encrypted lofi :)
This all seemed to work. I then enabled NFS sharing and copied some data from another PC onto the pool. After some copying, this reliably crashes the system.
I followed the instructions at http://wiki.illumos.org/display/illumos/How+To+Report+Problems, the crash.0 file is attached to this report. If there is some interest in fixing this problem I would be happy to provide also the full crash dump files.
I'm also willing to do some experiments on my setup if desired.
Also attached you find the outputs of "zpool status" and "lofiadm"

I also tried to test the lofi side, I set up the encrypted loop-back and did some concurrent writes with "dd" onto the /dev/lofi/* devices, this also works fine.
I do not know how to proceed further, is this the proper place to report these issues? Any kind of response would be nice :)
