Updated piranha packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
Piranha provides high-availability and load-balancing services for Red Hat Enterprise Linux. The piranha packages contain various tools to administer and configure the Linux Virtual Server (LVS), as well as the heartbeat and failover components. LVS is a dynamically-adjusted kernel routing mechanism that provides load balancing, primarily for Web and FTP servers.

Bug Fixes

Previously, the lvsd daemon did not properly activate the "sorry server" fallback service when all real servers were unavailable. Consequently, incoming traffic for a virtual service with no available real servers was not directed to "sorry server". This bug has been fixed and the lvsd daemon now properly activates "sorry server" when no real servers are available.
In certain cases, most often caused by brief network outages, high latency between directors, or aggressive keepalive and deadtime settings, the lvsd daemon did not properly terminate when signaled by the pulse daemon. Consequently, lvsd ran on both master and backup directories having multiple virtual IPs (VIPs). With this update, lvsd has been modified to correctly catch and handle all signals from the pulse daemon. As a result, the redundant VIP is now properly removed.
Users of piranha are advised to upgrade to these updated packages, which fix these bugs.
