Btrfs devel - Jan 2013 - Changing metadata block size after the fact

Hi,

I have an existing btrfs filesystem which was initialized with defaults. I
want to increase the metadata block size, but after reading wiki/man pages
etc. have come to the conclusion that this does not seem to be possible.
Is this correct, and the only way would be backup/mkfs with -l/restore?

thanks
Holger

   Correct, you can''t change the metadata block size once the FS has
been created.
