Drive F2Fs Support
Information
Builds now have experimental support for F2FS for /data and /cache. A compatible recovery is requiried.
WARNING
The F2FS version used by CM is newer than the one used by existing ROMs, recoveries and custom kernels. Features like inline_dentry and inline_data have been enabled to save disk space and improve the performance. Those features are not available on older kernels and this can cause corruption and data loss if you switch back! Just rebooting into a unsupported recovery or any other f2fs kernel can be enough to corrupt your userdata partition. Always make a backup when you switch ROMs!
F2fs is NOT supported on /system and it will never be!

Convert to cm's f2fs from any other fs/rom
It will wipe your userdata!
  • If you're already on f2fs for any reason, flash a factory image to revert to stock partitions (DO NOT USE ANY OTHER WAY TO REVERT TO EXT4)
  • Download the this recovery
  • Sideload it via fastboot boot recovery.img
  • Go to wipe > data > Repair or Change File System > f2fs
  • Go to wipe > cache > Repair or Change File System > f2fs
  • Reboot and enjoy

Let me warn you: some grouper users with ext4 had problems booting on the today build, I haven't test it yet on tilapia (with ext4), but I can tell for sure f2fs is working (I have to convert mine back to ext4). Will report later.
