Hello, All

I have not found any documen= tation about how to prepend LV with some free space
.
P= ossible use case - we have LV with filesystem and data on it. But to migrat= e this LV to KVM virtual machine we need to craft partition inside this LV = with already existing data.

I know it is possible = to create new LV and copy data here, but it could be time consuming for big= LVs.

So, Is there any way to prepend LV with some= free space ?

Thanks in advance,
