Because I need to backup data from Fedora 6, I use rsync to backup
machine A and test iscsi between machine B and iscsi storage.
So the data from A will through B into storage.
The rsync is working with error messages

The rsync is working with error messages, but the messages do not
happen all the times.
This is the messages file

In your log it looks like you are using a RHEL or Centos kernel and you
are using iser, and I do not see any 1020 errors like below.
For the problem in the log on your people.chu.edu.tw page it looks like
you are sending more IO than the target can handle. I would increase the
scsi command timeout and/or decrease the iscsi/scsi queue settings. For
the latter reduce node.session.cmds_max.
For the 1020 errors do you have multiple machines connected to the iscsi
target at the same time? And if you do do they all have different
initiator names in /etc/iscsi/initiatorname.iscsi?

Hello,
Befrore I uninstall the Fedora 6, I build a Fedora 12 machine for
testing.
But I still get some problems.
iscsid: Kernel reported iSCSI connection 1:0 error (1020) state (3)
I googled it and found this page 'https://bugzilla.redhat.com/
show_bug.cgi?id=583581'.
Although I didn't run CHAP, I upgrade the kernel to
2.6.32.12-114.fc12.i686.PAE.
(iscsi-initiator-utils-6.2.0.870-10.fc12.1.i686)
It sometimes show
May 10 13:56:40 milk kernel: connection1:0: detected conn error (1020)
May 10 13:56:41 milk iscsid: Kernel reported iSCSI connection 1:0
error (1020) state (3)
May 10 13:56:43 milk iscsid: connection1:0 is operational after
recovery (1 attempts)
Do you start seeing this right when you log in or is it after doing some
IO or doing some other operation like logging in other sessions? 1020
means that the target disconnected from us (disconnected tcp/ip
connection) for some unknown reason.
Could you send all of the /var/log/messages.
And what target are you using? Is it scsi-target-utils or IET or stgt or
some target from a hardware vendor?
