RHBA-2019:2103 - Bug Fix Advisory

Topic

An update for sbd is now available for Red Hat Enterprise Linux 7.

Description

The sbd packages provide integration with hardware-based watchdogs allowing the SBD utility to be used as a cluster-fencing device. SBD watches the cluster process and initiates a hardware reset if one of the processes fails or the node loses quorum.

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.7 Release Notes linked from the References section.

Users of sbd are advised to upgrade to these updated packages.
