istgt on shared IP

dignus · Oct 14, 2013

Hi all,

I've configured istgt successfully on this machine. But in order to get fail-over working to my other BSD node (shared JBOD), I added an IP alias to the interface. Alias itself works, but istgt gives me weird errors when I want to use this IP for a portal:

Code:

Oct 14 12:59:43 san-head1 istgt[7150]: istgt_iscsi.c:2479:istgt_iscsi_op_login: ***ERROR*** lu_find_target() failed
Oct 14 12:59:44 san-head1 istgt[7150]: istgt_lu.c: 524:istgt_lu_find_target: ***WARNING*** can't find target iqn.2013-10.example.com:disk1

The initiators can connect successfully to this target. What is also interesting to see, is that when I kill all iscsi daemons on my initiators, the log lines still appear every second while tcpdump tells me there's no traffic coming to the portal's TCP port. To make things things even worse, the disk "iqn.2013-10.example.com:disk1" doesn't exist in my setup:

Code:

[root@san-head1 /usr/local/etc/istgt]# grep disk1 *
istgt.conf:    Comment                  "Sample Disk (iqn.2013-10.lan.cloud:idisk1)" 
istgt.conf:    TargetName               disk1
istgtcontrol.conf:    TargetName   "iqn.2013-10.lan.cloud:disk1"

Anyone who has any idea where to look for this?
