Looking to add storage to your Oracle Cloud Infrastructure (OCI) instance? Here’s a step-by-step guide to creating and attaching a new block volume in no time! 💾

Step 1: Create a New Block Volume

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

2️⃣ Navigate to Block Volumes:

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

Step 2: Attach the Block Volume to Your Instance

1️⃣ Locate Your Compute Instance:

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

2️⃣ Attach the Block Volume:

• On the instance’s details page, go to Attached Block Volumes.
• Click Attach Block Volume and fill in:
  • Attachment Type: Use Paravirtualized (default) or iSCSI.
  • Block Volume: Select the 200 GB volume created earlier.
• Click Attach.

Step 3: Configure the Volume on Your Instance

1️⃣ Log in to the Instance:

• Use SSH to connect to your instance.

2️⃣ Identify the New Volume:

• Run the following command to list all available disks:

  lsblk
  

  The new volume will appear (e.g., /dev/sdb).

3️⃣ Partition and Format the Volume:

• Partition the disk (if needed):

  sudo fdisk /dev/sdb
  

• Format the partition with ext4:

  sudo mkfs.ext4 /dev/sdb
  

4️⃣ Mount the Volume:

• Create a mount point:

  sudo mkdir /mnt/additional-storage
  

• Mount the volume:

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

5️⃣ Optional: Automate Mounting at Boot:

• Add the following entry to /etc/fstab for automatic mounting:

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