Is it possible to enable compression on existing F2FS filesystem?

I just noticed f2fs now have transparent compression support, but I can’t find information on how to enable it. Anyone know how to do this?

man mkfs.f2fs do not mention compression?

According to this, has to be enabled at creation of the filesystem:

It would be strange if it wasn’t, considering the file system supports even just compressing a bunch of files.
https://www.kernel.org/doc/html/latest/filesystems/f2fs.html

You would have to write again your existing files for the new setting to apply though.

Not worth the effort, see old forum, there is a post about it.

Just use plain f2fs.

Where?
And recently? Because F2FS gained lzo-rle and zstd as of lately.

I would have posted it anyway despite your “Where?”

And what part of that would suggest compression is not worth the effort?
