Modify the hard disk name and boot-mounted hard disk under ubuntu
1. View information
Check the volume label and uuid of all hard disk partitions on the computer,
sudo blkid
/dev/sda1: LABEL="win7" UUID="40305E93305E9030" TYPE="ntfs"
/dev/sda5: LABEL="software" UUID="823E2D6213AF89BD" TYPE="ntfs"
/dev/sdb1: LABEL="learning" UUID="CCBC9A082598C349" TYPE="ntfs"
/dev/sdb2: LABEL="datadisk" UUID="40e93235-b5d1-48c4-936c-212029bda05a" TYPE="ext4"
/dev/sdc1: UUID="7350922f-c69c-4f33-84e0-befd8b42d2f6" TYPE="swap"
/dev/sdd1: UUID="3002feb1-dceb-441d-bfd2-31243e336d39" TYPE="ext4"、
- #In order to better distinguish the hard disk partitions, modify the volume label (similar to Windows C, D, E, F disk)
sudo e2label /dev/sdb2 data
- 2. Mount processing
View the hard disk number to be mounted
df -h
# 以下只显示常用的
Filesystem Size Used Avail Use% Mounted on
tmpfs 13G 19M 13G 1% /run
/dev/sda3 113G 14G 94G 13% /
/dev/sda1 453M 141M 286M 33% /boot
/dev/sda4 479G 43G 422G 7% /home
/dev/sdb1 7.3T 729G 6.2T 11% /home/data
If it /dev/sdb1is what we want to mount (shown under mounted on here, I have processed it and put it in /home/data)
Then, pop up the partition whose name you want to modify,
sudo umount /dev/sdb2
- Mount the hard drive
sudo mount /dev/sdb2 /home/data
- 3. Modify auto mount
The partition is automatically mounted after the system restarts
sudo vim /etc/fstab
Add in the last line
/dev/sdb2 /home/data ext4 defaults 0 1
# or
# 编号，查看第一步
UUID="40e93235-b5d1-48c4-936c-212029bda05a" /home/data ext4 defaults 0 1
4. Hard disk permission settings
Modify the folder permissions to other users, avoid using it sudoto modify the files in the hard disk
sudo chown -R 你的用户名 /home/data
sudo chmod 777 /home/data
# or
sudo chome -R 775 /home/data
