OpenWRT/LEDE 分区并挂载移动硬盘

去年年初,为了体验4k的“塞尔达传说-旷野之息”,我升级了我的电脑,并在18年不断完善,目前经过optane加速的4T硬盘,速度提升非常显著,很是喜欢。但电脑里有些录音,以及家庭照片,想随时观看,而不想开电脑,另外也起到备份的作用(数据无价),所以一直在考虑采购一台NAS,但感觉现在的NAS及配件(硬盘)功能比较弱(其实就是没米。。。),所以就考虑利用现有资源,把1T的闲置移动硬盘挂载到 WRT1200路由器下,这样 Win/Mac/手机 通过sshfs/samba远程挂载目录,这样可以体验简易NAS,等时机成熟了再考虑NAS,此篇主要总结如何挂载移动硬盘,由于环境版本的不同,总结中的内容可能跟读者遇到的会有少许差异,如遇到问题,可自行google或baidu

有时候通过LEDE的luci直接挂载不起作用,也弄不明白为啥,所以还是CLI最靠谱。另外在openwrt里,移动硬盘的格式最好是ext3或ext4,这样效果高,问题少。另外就是最开始我想用sshfs,但后来发现windows访问sshfs效果非常不好,所以对于windows,就换回了samba服务器,速度不错,可以达到平均60MB/s 上下

另外Samba配置,可以参考我之前的文章 Deploy Samba on OpenWRT

1. 国内更新源,这样就可以随便更新软件了
