Among these, the 0.4.9 heartbeat, an application that checks if the machines in the cluster are responding appropriately, allowing the service to be always active, and performs corrections in the DRBD, a network disk replication device that obtains online disk mirroring. These modifications can be downloaded by all Conectiva Linux users and are available for the whole community. The Heartbeat 0.4.9 main feature is that it is more stable than the previous version, since it was divided into three more specific purpose packages. Conectiva developers have corrected some bugs related to cluster start up process, and the DRBD repair is connected with a problem that happens when the device is used with more than five shared volumes. While the kernel new version is not released, Conectiva is providing a patch that can be used to compile a kernel with the same number of volumes. Next Projects Due to its open source code, the updates and new features brought in to the Linux OS are a constant. In this scenario, Conectiva is among the active participants, maintaining a specialized team of programmers and developers, releasing important modifications such as the APT (Advanced Package Tool) for .rpm packages announced at theend of last year accompanying the Conectiva Linux 6.0. The team is developing a new version of heartbeat with support to the resources transition activated by external elements, higher stability and improved use of the network band. They have also started working with real time technology and N cluster nodes. These projects will allow to maximize and facilitate the use of the Linux operating system in critical high performance operation missions.
