F2FS

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, install f2fs-tools from the official repositories.
Create the partition:
# mkfs.f2fs -l mylabel /dev/sdxY
where /dev/sdxY
is the target volume to format in F2FS.
Mounting a F2FS partition
Users will likely need to manually load the F2FS kernel module before mounting. Issue as root:
# modprobe f2fs
The partition can then be mounted:
# mount -t f2fs /dev/sdxY /mnt
Install Arch Linux on F2FS partition
With the latest installation media it is possible to install Arch linux with root located on a F2FS filesystem:
- Create the root partition as F2FS as described in section #Creating a F2FS partition.
- If your bootloader does not support F2FS, create a separate
/boot
partition using a filesystem that it does. - Continue with the installation procedure as per Installation guide#Mount the partitions until chrooted.
- Install f2fs-tools on the newly installed system as well.
- Regenerate the initramfs while chrooted.
The driver included in the kernel 4.6 or higher uses Crypto API for computing CRC32. Add crc32_generic
and crc32-pclmul
to the MODULES
array in /etc/mkinitcpio.conf
and regenerate the initramfs if the driver fails to load a CRC32 module at boot.
