MCA Tips Feed. 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.

MCA Tips Feed. 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."

MCA Tips Feed. Loadable kernel modules are cool because they let you add code to a running Linux kernel. But how do you know the code you add won't make your kernel a client of the Death Star? You don't. Unless you use signed kernel modules. Robert Chase explains how.

MCA Tips Feed. Oracle Solaris zones are referred to as lightweight virtualization because they impose no overhead on the virtualization layer and the applications running in the non-global zones. As a result, they are a perfect choice for high performance applications. Detlef Drewanz continues his overview of virtualization strategies with a focus on Oracle Linux Containers and Oracle Solaris zones.
