Step 1: Create a New Block Volume

1. Log in to OCI Console:
   Go to the OCI Console.

2. Navigate to Block Volumes:
   From the navigation menu, select Storage > Block Storage > Block Volumes.

3. Create a New Volume:

   • Click Create Block Volume.
   • Provide the following details:
     • Name: Enter a name for the block volume (e.g., additional-storage).
     • Availability Domain: Select the same availability domain as your instance.
     • Size: Enter 200 GB.
     • Performance: Choose the performance level (Balanced, Higher, or Lower).
   • Click Create Block Volume.

Step 2: Attach the Block Volume to Your Instance

1. Locate Your Compute Instance:

   • Navigate to Compute > Instances in the OCI navigation menu.
   • Click on your instance to open its details page.

2. Attach the Block Volume:

   • On the instance details page, click Attached Block Volumes.
   • Click Attach Block Volume and provide the following:
     • Attachment Type: Use Paravirtualized or iSCSI (default: Paravirtualized).
     • Block Volume: Select the 200 GB block volume you created earlier.
   • Click Attach.

Step 3: Configure the Volume on the Instance

Once the block volume is attached, configure it on the compute instance.

1. Log in to the Instance:
   Use SSH to connect to your instance.

2. Identify the New Volume:
   Run the command to list available disks:

   lsblk
   

   The new disk should appear (e.g., /dev/sdb).

3. Partition and Format the Volume:

   • Partition the disk (if needed):

     sudo fdisk /dev/sdb
     

   • Format the partition with the ext4 file system:

     sudo mkfs.ext4 /dev/sdb
     

4. Mount the Volume:

   • Create a mount point:

     sudo mkdir /mnt/additional-storage
     

   • Mount the volume:

     sudo mount /dev/sdb /mnt/additional-storage
     

5. Update /etc/fstab (Optional):
   To make the volume mount automatically at boot, add an entry to /etc/fstab:

   echo '/dev/sdb /mnt/additional-storage ext4 defaults 0 0' | sudo tee -a /etc/fstab
