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.
