F2FS (Flash-Friendly File System) is a file system intended for NAND-based flash memory. It is supported from kernel 3.8 onwards.

Creating a F2FS partition

In order to create a F2FS partition, you need to install package f2fs-tools from the official repositories.

Create the partition:

# mkfs.f2fs /dev/sdxY

where /dev/sdxY is the volume that you wish to format in F2FS.

Mounting a F2FS partition

You may need to load the F2FS kernel module before mounting. Issue as root:

# modprobe f2fs

Then you can mount the partition:

# mount -t f2fs /dev/sdxY /mnt

Install Arch Linux on F2FS partition

With the latest installation media (2013.04.01) it is possible to install system on F2FS partition:

  1. Install f2fs-tools from official repositories while running arch from installation media.
  2. Load f2fs kernel module as described.
  3. Create root partition as F2FS as described.
  4. Create boot partition as ext4 (or any other supported filesystem).
  5. Mount, install and chroot system as per official installation guide.
  6. On installed system add f2fs to modules section in /etc/mkinitcpio.conf and remove fsck from hooks section since F2FS does not have fsck implementation yet.
  7. Don't forget to regenerate the initramfs image after that:
# mkinitcpio -p linux
