how to auto mount hdd on linux.md

Find all the available mountable file drives on your system:

sudo fdisk -l

output:

Disk /dev/ram0: 8 MiB, 8388608 bytes, 16384 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

Device             Start      End  Sectors   Size Type
/dev/mmcblk0p1        40 58720295 58720256    28G Microsoft basic data

Disk /dev/mmcblk0boot1: 8 MiB, 8388608 bytes, 16384 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk /dev/nvme0n1: 953.9 GiB, 1024209543168 bytes, 2000409264 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk /dev/zram0: 2 GiB, 2073931776 bytes, 506331 sectors
Units: sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

Look for your HDD based on Disk size (probably in GiB's) in our case it's:

• /dev/nvme0n1

  Disk /dev/nvme0n1: 953.9 GiB, 1024209543168 bytes, 2000409264 sectors
  Units: sectors of 1 * 512 = 512 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  

Now create a mount point where you want to attach your hdd on the system

sudo mkdir /media/LFS
sudo chmod 777 /media/LFS

Now we have to edit /etc/fstab so that it auto mounts the hdd on boot

sudo vim /etc/fstab

Edit the file and add a new line

# <file system> <mount point>         <type>          <options>      <dump> <pass>
/dev/sda        /media/LFS             ext4           defaults            0 1

And finally to mount the device run the below command

sudo mount -a

To see the available mounted device use command: df -H

Output:
