The software described in this documentation is either in Extended Support or Sustaining Support. See https://www.oracle.com/us/support/library/enterprise-linux-support-policies-069172.pdf for more information.
Oracle recommends that you upgrade the software described by this documentation as soon as possible.
Ideally, each node should be running the same version of the OCFS2 software and a compatible version of the Oracle Linux Unbreakable Enterprise Kernel (UEK). It is possible for a cluster to run with mixed versions of the OCFS2 and UEK software, for example, while you are performing a rolling update of a cluster. The cluster node that is running the lowest version of the software determines the set of usable features.
Use yum to install or upgrade the following packages to the same version on each node:
kernel-uekocfs2-tools
If you want to use the global heartbeat feature, you must
install ocfs2-tools-1.8.0-11 or later.
