How to Disk Partition Formatted in Openwrt System
How to Disk Partition Formatted in Openwrt System and Improve network performance⌗
如何在openwrt系统下给磁盘分区，并且是给固态硬盘分区
nvme标识最近在在淘宝买回一台小主机2.5g 4个网口的 cpu N5105 intel 赛扬,主要帮提升一下网络性能 升级wifi6，升级家庭网络结构，提升局域网络复制文件速度，同时解决了4k视频播放本地播放传输慢卡顿问题 店主省事帮我安装一openwrt x86系统，（不是arm，不是/dev/sda磁盘标识），没有把128G固态磁盘剩余的空间分区并格式化 导致我收到主机后，登录openwrt系统查看不到剩余空间，开始怀疑是否发错错了，不是128G的，还是64G的？？？ 询问店主后得知没有分区剩下的磁盘空间，所以需要买家自己行解决，如果不是it出生的用户怎么办，想想也是，不是it人员不用这部分空间也 也无所谓
解决分区问题，分三步⌗
1， 检查相关命令，是否有分区命令，没有需要安装，
opkg install fdisk
如果安装好后，使用fdisk -l 命令查看硬盘使用情况，分区情况，以及分区编号
2, 格式化未使用的空间,nvme0n1p1,nvme0n1p2己使用了，创建新分区nvme0n1p3
mkfs.ext3 /dev/nvme0n1p3
3, 挂载分区，使用命令临时挂载，一次性的，需要开机则挂机，则需要添加init.d命令，这里推荐用图形界面挂载比 比较简单,选择UUID,挂载点后点击保存即可
以下是用命令操作分区格式化的过程

Welcome to fdisk (util-linux 2.37.3).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
GPT PMBR size mismatch (2236959 != 180355071) will be corrected by write.
The backup GPT table is corrupt, but the primary appears OK, so that will be used.
The backup GPT table is not on the end of the device. This problem will be corrected by write.
This disk is currently in use - repartitioning is probably a bad idea.
It's recommended to umount all file systems, and swapoff all swap
partitions on this disk.
