Ok, that's interesting.
The mdb stack back-trace is indicating an assertion caused by the
code here:
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/
iscsi/iscsitgtd/iscsi_sess.c
At line 220, we see the start of the routine "sess_from_t10()"
As it then calls "t10_handle_destroy()" in line 247 this indicate
we are processing
a message of type "msg_shutdown_rsp"
But the iscsitgt daemon's state machine thinks this is wrong to
occur at this stage & core dumps.
The t10 state machine isn't having a problem with the message. The
problem is that within t10_handle_destroy() the daemon is cleaning up
some commands that are active, but will never receive a response. The
code is incorrectly looking at a command which is in the "Freeing"
state and attempts to free it. That's a invalid state transition and
the state machine correctly kicks it out.
One thing that is unusual here is that the daemon is in the process
of shutting down the connection. Why is the initiator closing the
connection. This is not normal, especially so since the initiator is
transferring data.
Well that my reading of what is happening, but it will be even more
interesting
to hear Rick McNeal's view on what's happening here!
Ok, I will try to reproduce the error on my system, although I have
snv_60
installed at the moment, and I am not yet using ZFS with the target.
I'm testing with the Microsoft iScsi Initiator at this moments, and
every
thing is fine so far.
Nicolas, were you just coping the files across to the iscsi target
when this
happened, or were you doing anything special or unusual?
Thanks
Nigel Smith
