Are you really sure that the kernel supports f2fs?

 grep F2FS /boot/config-3.8.3-203.fc18.x86_64
 # CONFIG_F2FS_FS is not set

You have to convince fedora kernel maintainers to enable the filesystem :-) Reassigning...

Comment 2 Maxim Prohorenko 2013-03-21 07:46:48 UTC
I build and install kernel module f2fs.ko.
But it does not solve my problem too.
Mount know about f2fs but can't mount disk formatted by mkfs.f2fs

Comment 3 Josh Boyer 2013-03-21 14:09:52 UTC
Yeah, we don't build this.  If you're building it yourself, that's fine but this isn't a fedora kernel problem.

You'll want to show the output of lsmod and /proc/filesystems after you load your driver.

Karel, I'm passing it back to you for now.  If you don't think this is an issue in util-linux then please just close it as NOTABUG or WONTFIX given the fedora kernel doesn't build this filesystem.

Comment 4 Karel Zak 2013-04-15 09:26:47 UTC
Note that libblkid is able to detect f2fs since util-linux 2.23.
