This readme provides a step-by-step guide for attaching an Oracle Block Volume to an instance and creating a partition, file system, and mounting the file system. It also includes instructions for updating the /etc/fstab file to automatically mount the disk when the system boots, rebooting the instance, and checking the file system. The guide al…

Oracle Attach BLOCK Volume to Instance

• Creating a partition with fdisk
• Creating an ext3 file system
• Mounting the file system
• Updating the /etc/fstab file
• Rebooting the instance
• Checking the file system

Preparation

see the volume in the console

lsblk

sudo fdisk -l

Creating a partition with fdisk

sudo fdisk /dev/sdb

When you press "m" and confirm the entry with Enter, the program will provide a page of available commands

1. use the entire disk space, press the "n" key and Enter.
2. The system will ask about the type of partition select "p" - primary.
3. The partition number select "1"

Save the changes by pressing "w" and confirm the selection with the Enter key.

see the volume in the console

lsblk

Creating an ext3 file system

sudo /sbin/mkfs.ext3 /dev/sdb1

Mounting the file system

Create a directory

sudo mkdir /oradiskvdb1

change the access rights to the directory. Only root and only read and write.

sudo chmod -R 660 /oradiskvdb1

Mount

sudo mount /dev/sdb1 /oradiskvdb1

Updating the /etc/fstab file

To mount the disk automatically when the system boots, edit the /etc/fstab file.

sudo nano /etc/fstab

At the very end of the file, insert the line:

/dev/sdb1 /oradiskvdb1 ext3 defaults 0 0

Rebooting the instance

sudo reboot

Checking the file system

lsblk

User Permissions

chown -R $USER:$USER /oradiskvdb1

Reference

• Connecting to Volumes With Consistent Device Paths
• Mounting a disk and creating partitions in Linux
• Permission Denied When Creating Directory or Writing a File

You might also to use the newer ext4 instead of ext3, but that's just my personal preference. But you probably should use /dev/oracleoci/oraclevda1 instead of /dev/sdb1 in the fstab if you have consistent device paths for your block volume.
