Thanks for your prompt reply and sorry for the delay with mine.
This particular installation is on Fedora 14 with
scsi-target-utils-1.0.18-2.fc14.x86_64. Unfortunately, we can't
stop/update tgtd now as the system is under heavy use.
We certified our system on CentOS 6.2 as well, but there I see even
older version :(
scsi-target-utils-1.0.14-4.el6.x86_64
How do you roll out the latest stable releases for CentOS? Or we will
have to build it?
Thank you,
Konstantin

Hi,
We use tgtd with >100 targets and from time to time we see failures of
tgt-admin --update <iqn>
with iqn predefined in a conf file. The reported failures are
# Adding target: test_aaa
tgtadm -C 0 --lld iscsi --op new --mode target --tid 401 -T test_aaa
tgtadm: this target already exists
Command:
tgtadm -C 0 --lld iscsi --op new --mode target --tid 401 -T test_aaa
exited with code: 22.
We discovered that calculation of 'tid' value happens in tgt-admin and
it seems like if tgtd is under a relatively high load
sub process_targets {
...
my @show_target = `tgtadm -C $control_port --op show --mode target`;
doesn't actually get the full list of targets, and then later on
calculated $next_tid actually clashes with already existing target id.
Sounds like mgmt bugs.
What version you use? The mgmt code was rewritten in 1.0.25 so it
would be great if you could try 1.0.24 and the latest.
Thanks.
