[Felix Blanke]

Hi,

is there any way to set/change the label after the filesystem has been created?


Best regards,
Felix

There was a patch to do that. But AFAICT this patch was never merged.
If you are interested look at

[Repost] btrfslabel - kernel space

https://kerneltrap.org/mailarchive/linux-btrfs/2010/1/4/6683133/thread

IIRC the user space utility, in case of a *unmounted* filesystem, is able to 
change a LABEL without patching the kernel.

True, I have to admit that my reply was not very clear.
The patches of which I posted the link, contains the command btrfslabel which 
is able to change a label.
Unfortunately the patches were never accepted.

If you are interested I can update and repost the patches.

Re: Set/change label

[Felix Blanke]

Hi,

ah ok :) I thought there is a way without the patch to change the label of unmounted
fs.

I am interested! If it is not to mutch work for you it would be great to have that
feature.
It's kind of strange that it is not possible to do that with the default btrfs
utilities, because it's such an elementary thing.

Thanks again for your help!


Regards,
Felix
