How to mount a new disk on a Linux cloud server

# Check the disk status and find a new disk /dev/vdb
fdisk -l

# Partition the data disk. Follow the prompts and enter: n, p, 1, press Enter twice, wq
# Enter n to add a new partition # Enter p to create a new primary partition # Specify the partition number, just enter 1 # Specify the starting sector, the default is fine, it is not recommended to change # Specify the ending sector, which represents the partition size. You can use K, M, G to specify the partition size. By default, all are allocated fdisk /dev/vdb

# Now find the newly added /dev/vdb1
fdisk -l

# Format the specified partition mkfs.ext4 /dev/vdb1

# Temporarily mount the partition, which will become invalid after reboot # Mount it in the /data directory mount /dev/vdb1 /data

# Unmount /data

# Permanent mount: Write new partition information # The first partition to be mounted, such as /dev/sdb1
# The mount point of the second partition, for example, mount it to /root/RepositoryDisk# The format of the third partition should be the same as the format specified when you formatted the partition yourself# For the fourth partition, just defaults and keep it consistent with the system# For the fifth partition, keep it consistent with the system, just enter 0# For the sixth partition, keep it consistent with the system, just enter 0#
# Append the following text to the /etc/fstab file echo /dev/vdb1 /data ext4 defaults,noatime 0 0 >> /etc/fstab
