"Conectiva has published several high availability update
solutions for Linux. 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."
