Hi Mike,
I'm just reviewing this for the iser disconnect change we're discussing,
and I noted that stop conn is called after ep_disconnect. I wasn't sure if
this is needed, or maybe bug or just something we can live with...
Here's the sequence of events I have collected with the RHEL 5.4

The refcouning method sounds good. If iser has cleaned up what gets set
in iscsi_iser_conn_bind once its ep_disconnect has completed, then you
should be ok. So iser_conn-ib_conn has to be NULLd so later when
iscsi_iser_conn_bind is called for the new conn it can be set.

I do hit this -EEXIST race from time to time when running things like
stop/start sequence.

nullifying iser_conn-ib_conn in iser_conn_terminate is problematic since
i_c_terminate is called in the e_disconnect flow where i_c_stop is call later

Remember that clients (especially Linux) doe cache blocks
locally
Doesn't kernel refresh the read cache for blocks at some intervals?
If I make a new file on target locally, and waiting for sometime,
hitting read command like ls on initiator side will read data from
block device, not from

Is NFS an option?

I'm new to SANs and iSCSI, and I'm lookin to a place to start from,

If you do not use ifaces, then IO will be routed based on the route table.
So I think probably, IO would go through the same NIC on the server. Is this
what you are seeing?
I don't actually have the env. setup yet. Right now I'm just trying to
determine what would be the best way to setup the

Ok so I guess working with old versions of open-iscsi is not accepted
here :). So I upgraded to the latest and greatest semi-stable
release, 871. I no longer see the is not queued messages and my
login and logout work fine. However this is the only the case if I
don't have my flash device
