Which module supports Linux-IO Target

[qingquan]

I want to set up an iscsi server
Who knows, please?
Which module supports Linux-IO Target.

Hi qingquan

The iSCSI target fabric is included since Linux 3.1.

The important kernel modules are target_core_mod and iscsi_target_mod, which should be in the kernel ...

Found here:
https://wiki.archlinux.org/title/ISCSI/LIO

That suggests the following kernel config options need to be enabled:
CONFIG_TARGET_CORE
https://cateee.net/lkddb/web-lkddb/TARGET_CORE.html
CONFIG_ISCSI_TARGET
https://cateee.net/lkddb/web-lkddb/ISCSI_TARGET.html

If you look at the kernel config:
http://tinycorelinux.net/12.x/x86_64/release/src/kernel/config-5.10.3-tinycore64
it shows:

# CONFIG_TARGET_CORE is not set

and  CONFIG_ISCSI_TARGET  does not exist since it requires  CONFIG_TARGET_CORE.

That means  Linux-IO Target  support is not included in your kernel.

Hi Rich
Thank you for your reply. I have learned skills from it.

TinyCorePure64-12.0 Not supported Linux-IO Target.
 sorry to hear that,I'm not up to the task of recompiling the kernel.
 Is there any other way? For example, install a tcz.

[Juanito]

You will need to re-compile the tinycore kernel - it's not difficult.

[qingquan]

Thanks to Juanito's encouragement, I downloaded the source code:
http://tinycorelinux.net/12.x/x86_64/release/src/kernel/linux-5.10.3-patched.txz
Next, how to get the source code,or how to set it up?

TARGET_CORE, ISCSI_TARGET,TCM_IBLOCK,TCM_FILEIO,TCM_PSCSI,TCM_USER

Thank you very much!

[Juanito]

You also need to download http://tinycorelinux.net/12.x/x86_64/release/src/kernel/config-5.10.3-tinycore64

Then:

Code: [Select]

tce-load -i compiletc perl5 ncursesw-dev bc glibc_apps elfutils-dev
cd linux-5.10.3
make mrproper
cp ../config-5.10.3-tinycore64 ./.config
make oldconfig
make menuconfig
..choose your new configuration options (set them as modules "m", then save and exit menuconfig

Then:

Code: [Select]

make
Once completed, you will need to copy the new vmlinuz and the new modules.

The new modules can used to create a new extension and the new vmlinuz will replace the existing tinycore vmlinuz64.

Hi Juanito

Compiling in a "Linux partition" is a good choice
http://tinycorelinux.net/12.x/x86_64/release/src/kernel/linux-5.10.3-patched.txz
http://tinycorelinux.net/12.x/x86_64/release/src/kernel/config-5.10.3-tinycore64

Code: [Select]

tce-load -iw compiletc.tcz
tce-load -iw perl5.tcz
tce-load -iw ncursesw-dev.tcz
tce-load -iw bc.tcz
tce-load -iw glibc_apps.tcz
tce-load -iw elfutils-dev.tcz
tar -xvf linux-5.10.3-patched.txz
cd linux-5.10.3
make mrproper
cp ../config-5.10.3-tinycore64 ./.config
make oldconfig
make menuconfig

What should I do next? thank you!

[Juanito]

Your vmlinuz seems large - it should be +/- 5,500KB.

You need to search the source tree for the additional modules you created (named *.ko) and make them into an extension.

[qingquan]

I'll try to deal with the module(name*.ko).

My kernel compiled to vmlinux, not vmliunz.
Do you need to compress? "gzip" or "make zImage"

thanks.

[Juanito]

How big is the file bzImage?

[qingquan]

Since it takes too long to compile, I didn't use it
"make bzImage" recompiles.
Not sure what file size this will give you.

I compressed vmlinux with winrar and got a file of 5,406 KB
Estimated compression should be at +/-5,400KB

What am I supposed to do now? Recompile it or gzip it?

[Juanito]

I asked because I have a feeling that we are using bzImage renamed to vmlinuz - @curaga can confirm.

[qingquan]

vmliunx -->vmliunz, what should I do? thanks.

vmliunx is a file generated with make and should not be compressed

[Juanito]

You can use bzImage directly or rename it to vmlinuz64 (with a "z") and replace the existing vmlinuz64.
