Attaching Block Volume Storage in Oracle Cloud Infrastructure Instance

 Attaching Block Volume Storage in Oracle Cloud Infrastructure Instance

1. Login to your OCI console, search for block volume or from the left hamburger menu, select "Storage" then "Block Volume" then "Create Block Volume"

2. Input your block volume name, compartment, AD, block volume size etc.

3. Once it is created, go to your instance and from left side you can see "Attach Block Volumes"  Then you need to make sure the attach type, compartment.

4. At the right of the side, you can see "iSCSI Commands & Information", click on that, you will see the commands to attach the volume to the instance.

5. Login to the linux instance. Issue the above commands. You can see a successful message.

6. Now to identify attach volume or device use unix command lsblk. This command helps you to identify the device for me its /dev/sbd

7. Format the disk using unix command fdisk and make file system using unix commnd  mkfs as you want in this case i am gong to make it as ext4 command is mkfs.ext4 /dev/sbb.

8. Create a folder directory for the mount mkdir /data

9. For permanent mounting you need to add an entry in /etc/fstab

/dev/sbd1 /data ext4 defaults,noatime,_netdev 0 2

10. Now we are going to mount. mount /dev/sdb1 /data

That's it. You can verify it using the command df -h
