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...
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
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.
Note that libblkid is able to detect f2fs since util-linux 2.23.
