First, check the system disk code:
Fdisk-ldisk/dev/SDA: 120.0 GB, 120034123776 bytes255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectorsunits = sector of 1*512 = 512 bytessector size (logical/physical): 512 bytes/512 bytesi/o size (minimum/optimal): 512 bytes/512 bytesdisk identifier: 0x000214d1 device start end block number ID system/dev/sda1 * 2048 217925631 108961792 83 Linux/dev/sda2 217927678 234440703 8256513 5 extensions/dev/sda5 2 17927680 234440703 8256512 82 Linux swap/solarisdisk/dev/SDB: 500.1 GB, 500107862016 bytes255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectorsunits = sector of 1*512 = 512 bytessector size (logical/physical): 512 bytes/4096 bytesi/o size (minimum/optimal): 4096 bytes/4096 bytesdisk identifier: 0xec689ddc device start end block number ID system/dev/sdb1 2052 471040703 235519326 7 HPFs/NTFS/exfat Partition 1 does not start with the physical sector boundary. /Dev/sdb2 471040704 976770467 252864882 7 HPFs/NTFS/exfatdisk/dev/SDC: 8178 MB, 8178892800 bytes92 heads, 57 sectors/track, 3046 cylinders, total 15974400 sectorsunits = sector of 1*512 = 512 bytessector size (logical/physical): 512 bytes/512 bytesi/o size (minimum/optimal): 512 bytes/512 bytesdisk identifier: 0x16c0ca45 device start end block number ID system/dev/sdc1 * 1552 15974399 7986424 B w95 FAT32
Note: the root directory/must be mounted before other directories.
Other mount points must be created directories.
Run the following command to view the uuid of another disk:
sudo blkid
The result is as follows:
/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"
Next, modify the automatically mounted configuration file:
sudo vim /etc/fstab
Modify as follows:
UUID=70fb376c-17c2-4ce1-a263-727f647949cf / ext4 errors=remount-ro 0 1# swap was on /dev/sda5 during installationUUID=0c5f073a-ad3f-414f-85c2-4af83f6a437f none swap sw 0 0UUID=11263962-9715-473f-9421-0b604e895aaa /data ext4 defaults 0 1UUID=88928fea-5dd3-47b1-9931-bb107d74371e /export ext4 defaults 0 1
The last two actions are newly added mount points.
Note: Do not set the Mount directory to/. If it overwrites the original root directory, the system will crash.
