首先，查看系統(tǒng)的磁盤代號(hào)：
fdisk -l
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectors
Units = 扇區(qū) of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

分區(qū) 1 未起始于物理扇區(qū)邊界。

Disk /dev/sdc: 8178 MB, 8178892800 bytes
92 heads, 57 sectors/track, 3046 cylinders, total 15974400 sectors

/dev/sdc1 * 1552 15974399 7986424 b W95 FAT32
注意：根目錄/一定要先于其他目錄被掛載起來。
其他的掛載點(diǎn)必須為已創(chuàng)建好的目錄。
使用如下命令查看其他磁盤的UUID：
sudo blkid
結(jié)果如下： /dev/sda1: UUID="70fb376c-17c2-4ce1-a263-727f647949cf" TYPE="ext4"
/dev/sda5: UUID="0c5f073a-ad3f-414f-85c2-4af83f6a437f" TYPE="swap"
/dev/sdb1: UUID="11263962-9715-473f-9421-0b604e895aaa" TYPE="ext4"
/dev/sdb2: UUID="88928fea-5dd3-47b1-9931-bb107d74371e" TYPE="ext4"
接下來修改自動(dòng)掛載的配置文件： sudo vim /etc/fstab
修改如下：UUID=70fb376c-17c2-4ce1-a263-727f647949cf / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=0c5f073a-ad3f-414f-85c2-4af83f6a437f none swap sw 0 0
UUID=11263962-9715-473f-9421-0b604e895aaa /data ext4 defaults 0 1
UUID=88928fea-5dd3-47b1-9931-bb107d74371e /export ext4 defaults 0 1
最后兩行為新加的掛載點(diǎn)。
注意，千萬不要將掛載目錄設(shè)置為/，否在會(huì)覆蓋原有的根目錄，系統(tǒng)就會(huì)掛掉。
