• Get inside the console of AWS→EC2→Volumes

  

  Configure the New Volume:

  • In the Create Volume wizard:

    • Volume Type: Select the type of volume (e.g., General Purpose SSD, Provisioned IOPS SSD, Magnetic).

    • Size (GiB): Specify the size of the volume in gigabytes.

    • Availability Zone: Choose the same availability zone as your EC2 instance to ensure they can be attached together.

  • Optionally, you can set other configurations such as Snapshot, Encryption, etc., based on your requirements.

    ---

    Attach the Volume to Your EC2 Instance:

    • Once the volume is created, go back to the Volumes dashboard.

    • Right-click on the newly created volume & select Attach Volume.

      

      NOTE: [this use to show clearly in white indication]

    • In the Instance field, select the EC2 instance to which you want to attach the volume.

    • Specify the Device (e.g., /dev/sdf, /dev/xvdf) [you’ll also name them when you attach it to the instance] where the volume will appear inside the instance.

      1. Partitioning the Disk

      To create a new partition on /dev/nvme1n1:

      1. Run fdisk to start partitioning:

          sudo fdisk /dev/nvme1n1
         

      2. In the fdisk menu:

         

         • Press n to create a new partition.

         • Accept the default partition number by pressing Enter.

         • Accept the default first sector by pressing Enter.

         • Accept the default last sector by pressing Enter (this will create a partition using the whole disk).

         • Press w to write the partition table to the disk and exit fdisk.

           

           

         • Now the partition /dev/nvme1n1p1 is created.

2. Formatting the Partition with XFS

Next, format the partition using the XFS filesystem:

1. Run the following command to format /dev/nvme1n1p1:

    sudo mkfs.xfs /dev/nvme1n1p1
   

3. Mount the Partition to /data/linux_karthi/

Now, mount the newly formatted partition to the desired directory:

1. Create the mount point if it doesn't exist:

    sudo mkdir -p /data/linux_karthi
   

2. Mount the partition to /data/linux_karthi:

    sudo mount /dev/nvme1n1p1 /data/linux_karthi
   

4. Making the Mount Permanent.

To make the mount persistent across reboots, add an entry to the /etc/fstab file:

1. Open /etc/fstab with an editor vi,

   • get the blkid first hand

     

    sudo vi /etc/fstab

2. Add the following line to the file:

    UUID  /data/linux_karthi  xfs  defaults  0  0
   

   

3. Save the file and exit the editor.

5. Verifying the Mount

To verify that the partition is mounted properly, use:

df -h /data/linux_karthi

This command will display the disk usage of the newly mounted partition. If everything is set up correctly, you'll see the details of /dev/nvme1n1p1 mounted at /data/linux_karthi.
