In Linux systems, you can mount a data disk to the reinstalled system using the following steps:

  1. Find the device name of the data disk. You can use the command lsblk or fdisk -l to view the list of disk devices in the system and find the corresponding data disk device name, such as /dev/sdb.
  2. Create a directory for mounting. You can choose to create a new directory under /mnt, such as /mnt/data, for mounting a data disk.
  3. Create a new directory named “data” in the “/mnt” directory.
  4. Mount the data disk. Use the mount command to attach the data disk to the destination directory.
  5. Mount the /dev/sdb device to the /mnt/data directory using sudo.
  6. If the data disk is managed through LVM (Logical Volume Management), additional steps need to be taken to mount the LVM partitions. First, use the pvscan command to find the device name of the LVM partition, then use the vgscan command to find the volume group name, and finally use the lvscan command to find the logical volume name. Mount the found logical volume to the target directory.
  7. Please run vgscan, lvscan, and mount /dev// to /mnt/data as root.
  8. Set up automatic mounting. To ensure that the data disk can be automatically mounted after system reboot, it is necessary to add the relevant mounting information to the /etc/fstab file.
  9. Add the line “/dev/sdb /mnt/data ext4 defaults 0 0” to the file /etc/fstab using the command sudo tee -a.
  10. If the data disk is an LVM partition, the corresponding LVM partition’s mounting information needs to be added to the /etc/fstab file.
  11. Append the line “/dev// /mnt/data ext4 defaults 0 0″ to the file /etc/fstab using sudo tee -a.
  12. Please replace and with the actual volume group name and logical volume name.
  13. Confirm that the mounting was successful. Execute the df -h command to view the list of mounted file systems, and verify that the data disk has been successfully mounted to the target directory.

The above steps are applicable to most Linux distributions, but may vary slightly depending on the specific distribution and file system type. Please adjust accordingly based on your actual situation.
