[Ocfs2-users] [ocfs2-announce] OCFS2 1.4.10-1 released

[Srinivas Eeda]

All,

We are pleased to announce the release of OCFS2 1.4.10-1 and OCFS2 tools 
1.6.3-2 for Oracle Linux 5 Update 7 and higher and Redhat Enterprise 
Linux 5 Update 7 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.

Red Hat's Enterprise Linux 5 users can download and install the relevant 
file system and tools packages from oss.oracle.com.

COMPATIBILITY

This release is fully compatible with earlier releases of OCFS2 1.4. 
Users can upgrade their nodes to the new version in a rolling manner.

RECOMMENDATION

This is just to remind users to add the "noatime" mount option to the 
mounts that hold the Oracle datafiles, redologs, archivelogs, voting 
file, etc. This is for OCFS2 1.4 only.

WHAT'S CHANGED

This release includes bug fixes, applicable backports from mainline and 
a new feature discontiguous block group. The new feature allows block 
groups to allocate discontiguous groups when contiguous region is not 
available.

To enable discontigous block group feature
    # tunefs.ocfs2 --fs-features=discontig-bg <dev>

To disable discontigous block group feature
     # tunefs.ocfs2 --fs-features=nodiscontig-bg <dev>

Users will need to install ocfs2-tools-1.6.3-2 to enable/disable 
discontigous block group feature
