Tech Article: Preventing Silent Data Corruption in Oracle Linux
Linux, like any OS, is vulnerable to silent data corruption. It can be caused by a faulty component or sysadmin error. It's nearly impossible to detect. But it's not impossible to prevent. EMC, Emulex, and Oracle partnered up on an end-to-end solution.

Blog: How to Treat an NFS File As a Block Storage Device
More about the dm-nfs kernel module, courtesy of Lenz Grimmer. If you want to work with block-based shared storage devices such as ocfs2, but you don't have iSCSI or SAN storage, you can use NFS, instead. Just create an NFS file that will contain the block-based shared storage device. In fact, you can create several shared storage devices that way. And use the "dm nfs" utility to create a device map. Lenz Grimmer expands on Wim's original blog.

Blog: How to Set Up a Global Heartbeat with OCFS2
Wim explains how to set up a global heartbeat on your site with OCFS2. In case you don't know, a heartbeat is how one file system lets others file systems know it is alive. When you have lots of devices sending each other heartbeats, the overhead becomes a problem. A global heartbeat in essence lets several devices share a single "beat."
