Add a new hard disk/partition

Updated on: 5.Dec.2020

To view the partitions & hard disks:

        sudo fdisk -l

To view the mount points :

        sudo mount -l

To mount a partition to the OS:

        sudo mount /dev/sdb1 /mnt

        (where ‘/dev/sdb1’ is the partition and ‘/mnt’ is the access point).

To unmount a partition:

        sudo umount /mnt

Note: you may mount a partition into user’s home folder as well. But, this requires to create a physical directory before mounting the partition.

        sudo mount /dev/sdb1 /home/user/mnt

        (where ‘mnt’ must be a directory before the mount command)

Note:  ‘mount’ effect will live until the server restart To permanently mount the directory, you must edit ‘/etc/fstab’ file. If the directory has blank space, replace it with ‘\040’ which will be interpreted as space character.

To mount a directory (not a partition) into another directory (for another user). For example, in the FTP service, user A and user B would like to access the same directory located in different partition/directory.

Below is the config that I have added to fstab in the office server where I’m mounting the “Source Codes” directory into “/home/lhw/Source Codes” so that I can access the source code in the different hard disk/partition. 

UUID=2CFA4F8CFA4F516E   /mnt/backup     ntfs    rw      0       0
UUID=3060658D60655B1C   /mnt/backup2    ntfs    rw      0       0
/mnt/backup/Source\040Codes     /home/lhw/Source\040Codes       none    bind    0       0

To view hard disk/partition usage,

        df -H

To view the usage in the directory, run the following command. (You have to install ncdu).

ncdu
