iSCSI install failed

ROCK Pi Series Using ROCK Pi E
1

Hi everyone,

I tried to install iSCSI with the command apt-get install open-iscsi, but it failed loading the iscsi daemon.

I have modified /etc/initiatorname.iscsi with the target IQN and did not change the iscsid.conf as I did not set any authentication on the target but no luck.
I tried with Windows and it works well so the issue is definitely not in the Target side
Anyone has succeeded in getting that working?

Hi all,

I flashed the latest Armbian version and the installation of open-iscsi worked like a charm, however the kernel is not stable and the OTG does not work. There is definitely something wrong with the debian version.

Does someoen know what to do?

Thank you,
Armandooooo

Hi. We are forcing on this issue now.

Hi Stephen,

Were you able to find a solution to get the iSCSI working properly?
It seems like we should be loading “modprobe iscsi_tcp” but it failed because the iscsi_tcp.ko is not loaded in the kernel.

Thank you,
Armandooooo

@Armandooooo

Sorry for the late reply.
Can you upgrade kernel to 4.4.194-20 and test again?

Modify file /etc/apt/sources.list.d/apt-radxa-com.list like this:

Buster

deb http://apt.radxa.com/buster-stable/ buster main
deb http://apt.radxa.com/buster-testing/ buster main

Focal

deb http://apt.radxa.com/focal-stable/ focal main
deb http://apt.radxa.com/focal-testing/ focal main

And install needed packages.

sudo apt update
sudo apt install -y linux-4.4-rock-pi-e-latest
sudo reboot

Reboot ROCK Pi E and execute command modprobe iscsi_tcp to load iscsi_tcp module.

Hi Stephen,

I was able to load the iscsi_tcp module and initiate connection with the iscsi lun. However the connection seems not stable, I have a lot of ping time out that are dropped in the console. Do you know what can cause this? It cannot be by home network:

Can you share how to config this two files:

/etc/iscsi/iscsid.conf 
/etc/iscsi/initiatorname.iscsi

and what is your target device ?

Hi,

I restarted from a fresh image. On my server side, the configuration is without authentication to start, I will set it once it is working properly:

image
image1845×1005 73.4 KB

I did not set anything particular for the iscsid.conf and initiatorname.iscsi.
After I run : #apt-get install open-iscsi
I did the following in sequence:
#iscsiadm -m discovery -t st -p 192.168.0.10
That returned my iscsi server:
192.168.0.10:3260,1 iqn.2004-04.com.qnap:ts-453pro:iscsi.nsw.ef0d6e
Then I run:
iscsiadm --mode node --targetname iqn.2004-04.com.qnap:ts-453pro:iscsi.nsw.ef0d6e --portal 192.168.0.10:3260 --login

At this stage, things seem to work… Except when I fire my first command:

You see above connection errors… Do you know what can it be?

However I could connect it through modprobe:
modprobe g_mass_storage file=/piusb.bin stall=0 removable=1 ro=1

Thank you,
