f2fs （Flash-Friendly File System)有很多对SSD友好的特性，主要特性包括：

  • 基于日志结构
  • 聚焦于优化日志结构中的wander tree的雪崩效应和清除代价

此外，它还充分利用了SSD的内部的某些特殊指令，以减小WAF，值得试用、借鉴。下边分享了Linux 环境部署f2-fs的步骤。（注意部署前，需要确认内核已经支持，3.10默认的kernel 不支持，4.18的内核可以支持。）

遵循ReadMe 编译

You should install the following packages.

  • libuuid-devel or uuid-dev
  • pkg-config
  • autoconf
  • libtool
  • libselinux1-dev

Initial compilation

Before compilation initially, autoconf/automake tools should be run.

#./autogen.sh

How to compile

#./configure
#make
#make install

格式化f2-fs盘并挂载

insmod f2fs.ko

nvme format /dev/nvme1n1

mkfs.f2fs /dev/nvme1n1

mkdir -p /mnt/f2fs

mount -t f2fs /dev/nvme1n1 /mnt/f2fs
