[Ocfs2-announce] OCFS2 1.4.4-1 and OCFS2 Tools 1.4.3-1 released
All, We are pleased to announce the release of OCFS2 1.4.4-1 and OCFS2 Tools 1.4.3-1 for Oracle's and Red Hat's Enterprise Linux 5 Update 2 and higher. Oracle's Unbreakable Linux Network users who are subscribing to the "OCFS2 1.4 packages for Enterprise Linux 5" channel can upgrade to this release by running up2date. http://oss.oracle.com/pipermail/el-errata/2009-September/001170.html http://oss.oracle.com/pipermail/el-errata/2009-September/001169.html Red Hat's Enterprise Linux 5 users can download and install the relevant file system and tools packages from oss.oracle.com. http://oss.oracle.com/projects/ocfs2/files/RedHat/RHEL5/ http://oss.oracle.com/projects/ocfs2-tools/files/RedHat/RHEL5/ Novell's SUSE Linux Enterprise Server's (SLES10 SP2) latest kernel already includes elements of this release. Users should contact Novell for more information about OCFS2 on SLES10. COMPATIBILITY This release is fully compatible with OCFS2 1.4.1 and 1.4.2. Users can upgrade their nodes to the new version in a rolling manner if they so choose. This release is on-disk compatible with OCFS2 1.2.x. Users can install the software and mount the older volumes as-is. However, as the two releases are not network compatible, a rolling upgrade from 1.2 to 1.4 is not allowed. NEW RECOMMENDATION Users should add the "noatime" mount option to the mounts that hold the Oracle datafiles, redologs, archivelogs, voting file, etc. This is because OCFS2 1.4 supports atime (access time) which makes it update inodes even on a read. Like ls -l. As tracking access time is not useful for the database, users are advised to disable it for such mounts. WHAT'S CHANGED This release includes few bug fixes and a performance improvement. The main bug fixed concerns unlinked file not releasing space. The file system now scans the orphan directory at a regular interval to delete orphaned files that are no longer in use. This workload is spread evenly across all nodes in the cluster. The fsck performance has been significantly improved. fsck.ocfs2 now aggressively caches the metadata blocks inorder to reduce the time it takes to check a volume. Users can take advantage of this by running fsck.ocfs2 on a node with lots of free memory.
