no dm mirror in the kernel

marcz · January 18, 2019

I find quite strange that CONFIG_DM_MIRROR is not set in the kernel. It makes impossible under lvm to have logical volume mirror, and I just experienced an impossibility to make a pvmove to change one drive for another one. All my filesystems are built upon lvm, the only possibility would be to rebuild a kernel. But I find it quite heavy, since I have to platforms bananapi and espressobin; and it needs to be done for each release.

But why no have built dm-mirror as module with the usual CONFIG_DM_MIRROR=m ?

Werner · January 18, 2019

Maybe because no one had a need for it yet.

You can build your own kernel and edit the config using the build script: https://github.com/armbian/build

If you think this might be useful for others feel free to send a PR with the changes to the kernel config so all future builds include this.

WIP. If you need it faster either donate or build yourself using the tools mentioned above. Either way give some feedback if it worked (the module or donation )

perhaps an idea using " compile.sh " and select particular option from kernel ( save .config in user space )

KERNEL_CONFIGURE=yes

Done. Go checkout dm-mirror branch and build.

Quardex · September 24, 2020

Thanks a lot all!

Firstly will try compile..

Tried build branch twice. Failed atm..

root@orangepione:~# modprobe dm-mirror
modprobe: FATAL: Module dm-mirror not found in directory /lib/modules/5.8.11-sunxi

Seems I need add that into my action.

modules is there. However there is not much what we can further do about that if - for example- there is an upstream issue with it.

dolphs · September 29, 2020

@Quardex - OPiOne is a H3 board isn't it , well current branch should be fine indeed

Nevertheless perhaps you can give kernel 5.9 a go ( currently rc7, production ready in about 2,5 weeks imho )

Try building with e.g. ( assuming Debian and no Desktop ) :

./compile.sh BRANCH=current RELEASE=buster BUILD_MINIMAL=yes BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=yes BOARD=orangepione

Go to kernel configuration and select :

~~" Device Drivers ", " <M> DAX: direct access to differentiated memory "~~

Uhm DAX was in kernel 5.9 (rc5) an issue if I remember correctly, well your module should be here, also for 5.8 that is no difference :

" Device Drivers " -> ", " Multiple devices driver support (RAID and LVM) ---> ", " <M> Mirror Target ".

I just checked out and indeed it is not selected so enable <M> and give it a go.

Perhaps more dependencies needed, I am not sure but you should be able to take your pick and build it according your needs.

It should build and hopefully it helps you out

Atm when I try compile master brunch I got that error:

Which board?

Look at output/debug folder and check the compilation.txt for errors.

Try with setting EXTRAWIFI=no

With "EXTRAWIFI=no" compiled fine

Try to clear your cache directory. My builds from today seem fine: https://werner.armbian.de/Okt04/

We have an automated job which runs whenever things are changed to detect errors and there are none atm.

Nope, it wasn't.

After update the compilation was successful and the module worked properly.

Thank you all!
