Debian - open-iscsi error

[Schnippzle]

Hi all,
New time Tinkerboard user, long time pi user.  Trying to move away from a pi2 to a Tinkerboard as an NFS host with an iscsi attached LUN, but when I install open-iscsi I get the following:

Code:

Just as a follow up...

I have tried to amend my sources.list to only point to: deb  h t t p://ftp.de.debian.org/debian jessie main (no clickable links)

However when I re-install open-iscsi and run " sudo iscsiadm -m discovery -t st -p <target>" I get:

Code:

iscsiadm: can not connect to iSCSI daemon (111)!
iscsiadm: Could not scan /sys/class/iscsi_transport.
iscsiadm: Could not scan /sys/class/iscsi_transport.
iscsiadm: Could not scan /sys/class/iscsi_transport.
iscsiadm: iSCSI driver tcp is not loaded. Load the module then retry the command.

iscsiadm: Could not perform SendTargets discovery: iSCSI driver not found. Please make sure it is loaded, and retry the operation

[Schnippzle]

So, thinking that it'd be an idea to get the latest version (2.0.876) and compile myself, I now get the following errors when running "sudo make":

Code:

make -C libopeniscsiusr
make[1]: Entering directory '/home/linaro/Downloads/open-iscsi/libopeniscsiusr'

Will persist and keep trying

Have also tried v2.0.873 from the raspbian repo with the same results.

Base on this https://github.com/open-iscsi/open-iscsi
It shows it would need "iscsi_tcp.ko, libiscsi_tcp.ko, libiscsi.ko and scsi_transport_iscsi.ko" those kind of kernel module driver.

And after digging, may enable below kernel config.

Code:

CONFIG_INET=y
CONFIG_BLK_DEV_SD=y
CONFIG_SCSI_LOWLEVEL=y
CONFIG_ISCSI_TCP=m
CONFIG_SCSI_ISCSI_ATTRS=m

Then check from TinkerOS, it not include "CONFIG_ISCSI_TCP" & "CONFIG_SCSI_ISCSI_ATTRS".
So you can try to compile your own kernel & test it again.

-- compile at Tinker (v2.0.7)--
base: https://tinkerboarding.co.uk/wiki/index....are#Kernel (for x86 PC)

Install the related packages:

Code:

sudo apt-get update
sudo apt-get install git-core gitk git-gui device-tree-compiler mtools parted libssl-dev

Get source code (1.3~G):

Code:

git clone https://github.com/TinkerBoard/debian_kernel.git -b 2.0.7 --depth 1
cd debian_kernel

Modify Kernel config:
Adding following two lines in "/arch/arm/configs/miniarm-rk3288_defconfig"'s last line.

Code:

CONFIG_ISCSI_TCP=m
CONFIG_SCSI_ISCSI_ATTRS=m

Building Kernel image & modules:

Code:

make ARCH=arm miniarm-rk3288_defconfig -j4
make ARCH=arm zImage -j4
make ARCH=arm modules -j4 CFLAGS_MODULE=-Wno-misleading-indentation

Install Kernel image & modules:

Code:

sudo cp arch/arm/boot/zImage /boot
sudo make ARCH=arm modules_install

Reboot, then try again open-iscsi.

Holy cow, thank you so much for the assistance. I'm on the road at the moment but will try this asap.

Thanks again!

Attempted the proposed fix and got the following whilst installing open-iscsi

Code:

my bad...
It seems need to compile new kernel too...

Building Kernel image & modules:

Code:

make ARCH=arm miniarm-rk3288_defconfig -j4
make ARCH=arm zImage -j4
make ARCH=arm modules -j4 CFLAGS_MODULE=-Wno-misleading-indentation

(It may take some times)

install Kernel image & modules:

Code:

sudo cp arch/arm/boot/zImage /boot
sudo make ARCH=arm modules_install

reboot & try again

open-iscsi.service:

Code:

linaro@tinkerboard:~$ sudo systemctl status open-iscsi.service

[Schnippzle]

Thank you for the continued support. Before performing this, do I need to remove the open-iscsi packages to then re-install them after the kernel rebuild?

[Craz_tyle]

I'm not sure...since actually I don't know how to use open-iscsi...but should be no problem.

If have any concern or strange? remove it and re-install again...is very easy. haha

Thank you i've been using open-iscsi on the pi2 for a few years and it's generally been rock-solid with good performance.  As it's the only protocol that my NAS supports I'm kinda stuck with how I present LUNs to my fileserver (NFS host).

Will persevere and let you know how I get on!

[Schnippzle]

It's worked! Fantastic, thank you very much

Next query: If I ever need to do a kernel update/upgrade, do I need to perform that manually like you've shown me?
