Download Ocfs2 1.4.1-1

Oracle has released version 1.4.1-1 of its Ocfs2 file system. Ocfs2 focuses on both good performance and high availability in a clustered environment. For example, applications that are designed ‘cluster-aware’ can use parallel I/O for a higher throughput of the required data or achieve higher availability because data is stored in multiple places. For more information, we refer you to this page† The announcement on the mailing list of this latest release is as follows:

all,

We are pleased to announce the release of OCFS2 1.4. This release has been available with Novell’s SUSE Linux Enterprise Server (SLES10 SP2) for some time now. Today we are announcing the release of the same for Red Hat’s and Oracle’s Enterprise Linux (EL5 U2) distributions.

Before upgrading, users are encouraged to read the OCFS2 1.4 User’s Guide to learn about the new features, compatibility issues and also about the new file system defaults.

Oracle’s Unbreakable Linux Network users looking to upgrade to this release will need to subscribe to the “OCFS2 1.4 packages for Enterprise Linux 5” channel. ULN users who do not wish to upgrade to this release should not subscribe to this channel. They will keep getting the patch upgrades for their OCFS2 1.2 install.

Red Hat’s Enterprise Linux users will need to download and install the relevant file system and tools packages from http://oss.oracle.com/.

Please note that this release only works on EL5 U2 or later. The earliest supported kernel version is 2.6.18-92.el5. It will not work with the older kernels. Needless to add, users looking to use OCFS2 1.4 will have to upgrade to EL5 U2. This goes for both Red Hat’s and Oracle’s Enterprise Linux distributions.
