🗒 Tutorial


OCFS2 is a general-purpose clustered file system used in clustered environments to increase storage performance and availability. In Oracle Cloud Infrastructure, you can deploy OCFS2 clustered file systems through Read/Write - shareable block storage attached to an instance.

Note: For optimal OCFS2 file system performance, reduce the number of files with the OCFS2 filesystem. Applications such as Oracle e-Business Suite (EBS) or Oracle WebCenter Content (WCC) should leverage a separate NFS file system for directories containing large amounts of temporary files. During runtime, system administrators should actively archive, purge, remove, delete, and move any non-current files to one or more separate subdirectories or filesystems while regularly monitoring the OCFS2 filesystem file/inode usage.

These guides provide instructions on using ocfs2-tools to deploy and test a two node Oracle Cluster File System version 2 (OCFS2) on Oracle Cloud Infrastructure.


  • Prepare for an OCFS2 configuration
    • Configure security list
    • Create and attach a block volume
  • Install or upgrade the software required for OCFS2
  • Configure the cluster layout
  • Configure and start the O2CB cluster stack service
  • Create an OCFS2 volume
  • Mount an OCFS2 volume


Two Oracle Linux systems with the following configuration:

  • a non-root user with sudo permissions
  • Oracle Linux 8 or later and the latest UEK kernel
  • additional block volumes for use with OCFS2
