F2FS (Flash-Friendly File System) is a flash file system initially developed by Samsung Electronics for the Linux kernel.
The motive for F2FS was to build a file system that, from the start, takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks, eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.
Installation
Out of the box Alpine Linux doesnt support making F2FS partitions, that can be added with:
# apk add f2fs-tools
Formatting a partiton using F2FS
You can format a partition using F2FS with the following command:
/dev/sda1 is used as a example# mkfs.f2fs /dev/sda1
f2fs module
f2fs needs to be manually added to /etc/mkinitfs/mkinitfs.conf if you are using it for rootfs.
Otherwise add it to /etc/modules:
echo f2fs >> /etc/modules
You need the module to mount partitions that are not rootfs.
