Hi Luigi,

Hi Jerome,
thanks for the promptly reply. I'm not using the -fb branch.

Yes you are:

I have installed targetcli from centos rpm:
# rpm -qi fcoe-target-utils-2.0rc1.fb16-5.el6.noarch

See the version here? ....fb16...

I'm not sure what is the initscript you mention. I have in /etc/init.d/:
# ls fcoe-target iscsi*
fcoe-target  iscsi  iscsid

but afaik those are for the initiatior or fcoe-target...

Well, given the name of the redhat package, my best best would be fcoe-target :-)

I tryed to manually create the directory but nothing changed:

Mmmh. ok.

I'll have to take a look at that installing a centos 6.5 box, or we can wait for Andy (who maintains the fb branch) to be around, whichever comes first. I would still try that initscript first though :-)

# ll /sys/kernel/config/target/

the only difference I see is that the module is now used:
iscsi_target_mod      205464  1

and I can't rmmod it.

Hi Luigi,

I am not 100% sure of that, as you are using the -fb branch, but it
seems to me you haven't got the /sys/kernel/config/target/iscsi/
directory. Normally this is created by the initscript.

Can you either try creating it manually, and/or starting the target
service susing the initscript ?

Best,

hi everybody,
I write to you for a problem that sound as my simple mistake
but I can't really find a solution after googling and reading
official doc.

I'm trying to configure a iscsi target on a centos 6.5 box with
a custom kernel compiled from vanilla 3.16.3.

I have compile:
CONFIG_TARGET_CORE=m
CONFIG_ISCSI_TARGET=m
CONFIG_CONFIGFS_FS=m

I mount configfs:
# mount | grep config
configfs on /sys/kernel/config type configfs (rw)

manually load iscsi_target_mod (and this show nothing in dmesg)

and when I run targetcli ls command this is the output:
# targetcli ls
o- /
.....................................................................
[...]
   o- backstores
.......................................................... [...]
   | o- block ................................................ [0
Storage Object]
   | o- fileio ............................................... [0
Storage Object]
   | o- pscsi ................................................ [0
Storage Object]
   o- loopback ...................................................... [0
Targets]

I can't see "o- iscsi" so I can't create the iscsi target i need...

# targetcli version
targetcli version 2.0rc1.fb16

$ ls /sys/kernel/config/target/
core  version

# lsmod | grep scsi
iscsi_target_mod      205464  0
target_core_mod       229493  1 iscsi_target_mod
configfs               22151  3 iscsi_target_mod,target_core_mod
scsi_mod               93246  6
iscsi_target_mod,target_core_mod,sg,sd_mod,sr_mod,libata

any idea of what I can check?

many thanks in advance
Luigi
