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

src/gz arm_core https://mirrors.ustc.edu.cn/lede/releases/17.01.6/targets/mvebu/generic/packages
src/gz arm_base https://mirrors.ustc.edu.cn/lede/releases/17.01.6/packages/arm_cortex-a9_vfpv3/base
src/gz arm_luci https://mirrors.ustc.edu.cn/lede/releases/17.01.6/packages/arm_cortex-a9_vfpv3/luci
src/gz arm_packages https://mirrors.ustc.edu.cn/lede/releases/17.01.6/packages/arm_cortex-a9_vfpv3/packages
src/gz arm_routing https://mirrors.ustc.edu.cn/lede/releases/17.01.6/packages/arm_cortex-a9_vfpv3/routing
src/gz arm_telephony https://mirrors.ustc.edu.cn/lede/releases/17.01.6/packages/arm_cortex-a9_vfpv3/telephony

2. 通过“fdisk -l”来查看插入的移动硬盘

root@LEDE:~# fdisk -l
......
Disk /dev/sda: 931.5 GiB, 1000204885504 bytes, 1953525167 sectors

3. 重建移动硬盘的分区,并用ext4格式化

8G给/overlay,用于软件安装的空间;其余都给/extdisk,存放文件的空间

root@LEDE:~# fdisk /dev/sda

Welcome to fdisk (util-linux 2.29.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

4. 确认两个分区的信息

root@LEDE:/overlay# block info /dev/sda*
/dev/sda1: UUID="580b4d58-b30d-4d88-bd16-6456c9217658" VERSION="1.0" TYPE="ext4"
/dev/sda2: UUID="143409e7-a88c-4f49-ac96-b0f9687ca5c5" VERSION="1.0" TYPE="ext4"

5. 手动修改fstab(注意用Tab隔开,而不是空格),使其每次重启后自动挂载

root@LEDE:/overlay# more /etc/config/fstab

config 'global'
	option	anon_swap	'0'
	option	anon_mount	'0'
	option	auto_swap	'1'
	option	auto_mount	'1'
	option	delay_root	'5'
	option	check_fs	'0'

config 'mount'
	option	'target'	'/overlay'
	option	'device'	'/dev/sda1'
	option	'fstype'	'ext4'
	option	'options'	'rw,async'
	option	'enabled'	'1' #<<<
	option	'enabled_fsck'	'0'

config 'mount'
	option	'target'	'/extdisk'
	option	'device'	'/dev/sda2'
	option	'fstype'	'ext4'
	option	'options'	'rw,async'
	option	'enabled'	'1' #<<<
	option	'enabled_fsck'	'0'
