# Check the Tencent Cloud Server Data Hard Drive # We can see that there is a 20GB data disk that is not mounted. Look at the previous path /dev/vda1

# Execute fdisk /dev/vda1

# Enter n, p, 1, Enter, Enter, wq
# The VDA here is the name of the data hard disk we saw above. If it is not this, you need to replace it according to your actual disk name. If it is the same as mine, just copy it directly.

# Format as ext3 file system mkfs.ext3 /dev/vda1

# A - Create a new directory mkdir /home

# B - Mount the partition mount /dev/vda1 /home

echo '/dev/vda1 /home ext3 defaults 0 0' >> /etc/fstab

# Execute df -h

# The following is the execution result Filesystem Size Used Avail Use% Mounted on
