The official release version of Linux 2.6.34 features a number of noteworthy improvements to the code. In particular, the update includes a new filesystem known as “Ceph,” which is capable of managing petabytes worth of data stored in the cloud. While the new technology is promising, developer Sage Weil warns, “Ceph is still relatively new and experimental for something as conservative as storage, and only time and testing will change that.”
The updated kernel also features a second new filesystem called LogFS intended for use on flash storage devices. And in addition to fixing a number of bugs, the release offers improved performance due to networking and parallelization enhancements.
