這裡以rk3399為例，安裝的是ubuntu18.0.4伺服器版本
1）首先檢視磁碟是哪一塊
$ sudo
fdisk -l
disk /dev/mmcblk1: 58.5 gib, 62813896704 bytes, 122683392 sectors
units: sectors of 1 * 512 = 512 bytes
sector size (logical/physical): 512 bytes / 512 bytes
i/o size (minimum/optimal): 512 bytes / 512 bytes
disklabel type: gpt
disk identifier: 992df2c2-0170-4f66-9492-fbf320673eef
device start end sectors size type
/dev/mmcblk1p1 64 8063 8000 3.9m linux filesystem
/dev/mmcblk1p2 16384 24575 8192 4m linux filesystem
/dev/mmcblk1p3 24576 32767 8192 4m linux filesystem
/dev/mmcblk1p4 32768 262143 229376 112m efi system
/dev/mmcblk1p5 262144 122683358 122421215 58.4g linux filesystem
disk /dev/sda: 1.8 tib, 2000398931968 bytes, 3907029164 sectors
units: sectors of 1 * 512 = 512 bytes
sector size (logical/physical): 512 bytes / 512 bytes
i/o size (minimum/optimal): 512 bytes / 512 bytes
disklabel type: dos
disk identifier: 0x398f62b1
device boot start end sectors size id type
/dev/sda1 * 206848 3907026943 3906820096 1.8t 7 hpfs/ntfs/exfat
2）掛載
$ cd /mnt
$ sudo
mkdir sda1
$ sudo
mount /dev/sda1 /mnt/sda1
需要將磁碟格式化為可識別的格式，比如fat32
3）開機自動掛載
每次重啟，硬碟裝置標識始終為/dev/sda1
$ sudo blkid
/dev/mmcblk1: ptuuid=
"992df2c2-0170-4f66-9492-fbf320673eef" pttype=
"gpt"
/dev/mmcblk1p1: partlabel=
"loader1" partuuid=
"95d89d52-ca00-42d6-883f-50f5720ef37e"
/dev/mmcblk1p2: partlabel=
"loader2" partuuid=
"78be2786-acb9-4885-bb6c-77dddef5aac9"
/dev/mmcblk1p3: partlabel=
"trust" partuuid=
"a36bc2fb-b345-417b-8aef-b49ea06c1f7b"
/dev/mmcblk1p4: sec_type=
"msdos" label=
"boot" uuid=
"1121-c996" type=
"vfat" partlabel=
"boot" partuuid=
"cee6ebd4-da8f-4378-a430-05693004c5da"
/dev/mmcblk1p5: label=

"ext4" partlabel=
"rootfs" partuuid=

/dev/sda1: label=
"backup" uuid=
"16f0-0b2b" type=
"vfat" partuuid=
"5633890f-01"
$ sudo vim /etc/fstab
最後新增一行 /dev/sda1 /mnt/sda1 vfat defaults 0 2
# unconfigured fstab for base system
# /etc/fstab: static file system information.##
# /etc/fstab: static file system information.##
/dev/mmcblk1p4 /boot vfat defaults 0 2
/dev/sda1 /mnt/sda1 vfat defaults 0 2
$ sudo
mount -a
$ sudo
reboot
重啟驗證
linux掛載新硬碟，開機自動掛載
linux的硬碟識別 2.6 kernel以後,linux會將識別到的硬體裝置,在 dev 下建立相應的裝置檔案.如 sda 表示第1塊scsi硬碟.v,z b,2 f7 u hda 表示第1塊ide硬碟 即連線在第1個ide介面的master口上 scd0 表示第1個usb光碟機.當新增了新硬碟後...

掛在的命令是mount，當然可以把這個命令加到 etc rc.local裡。除此之外還有另外一種方法 etc fstab 新增新的內容 分割槽定位，可以給磁碟號，uuid或label，例如 dev sda2，uuid 6e9adac29ada85cd或label software 具體掛載點的位置，...
