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. 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. Yes, you can 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. Wim explains how.

MCA Tips Feed. Because tape is physically robust, it is the most reliable way to transport large amounts of data by, for instance, helicopter to an oil rig. But different tapes are written in different formats, and if the sysadmin on the oil rig doesn't have the right reader, you'd be out of luck, right? Not if you wrote to tape using the LTFS file system, and the sysadmin on the oil rig downloaded the free LTFS reader. Brian Zentz explains.

MCA Tips Feed. If you are not getting the performance you expect from your ZFS filesystem, I/O may be the culprit. To help, ZFS provides the Adaptive Replacement Cache, or ARC. But do you know how well the ARC is working? You will if you analyze it with DTrace probes. Brendan Gregg describes how.
