Linux-HA

<p>The Linux-HA (High-Availability Linux) project provides a <a href="/facts/High-availability_cluster/MNWwE5RX">high-availability</a> (<a href="/facts/Computer_cluster/mT7S1BcX">clustering</a>) solution for <a href="/facts/Linux/9FvCKSTq">Linux</a>, <a href="/facts/FreeBSD/RKsFTm7F">FreeBSD</a>, <a href="/facts/OpenBSD/xmPS9tek">OpenBSD</a>, <a href="/facts/Solaris_(operating_system)/KPfT98EJ">Solaris</a> and <a href="/facts/Mac_OS_X/Y93vVpTm">Mac OS X</a> which promotes <a href="/facts/Reliability_(engineering)/cd6AS5w3">reliability</a>, <a href="/facts/Availability/l8SGSyyf">availability</a>, and <a href="/facts/Serviceability_(computer)/w9nQfmJF">serviceability</a> (RAS).
</p><p>The project's main software product is Heartbeat, a <a href="/facts/GNU_General_Public_License/S75KhLSX">GPL</a>-licensed portable cluster management program for <a href="/facts/High-availability_cluster/MNWwE5RX">high-availability clustering</a>. Its most important features are:
</p>
<ul><li>no fixed maximum number of nodes - Heartbeat can be used to build large clusters as well as very simple ones</li>
<li>resource monitoring: resources can be automatically restarted or moved to another node on failure</li>
<li>fencing mechanism to remove failed nodes from the cluster</li>
<li>sophisticated policy-based resource management, resource inter-dependencies and constraints</li>
<li>time-based rules allow for different policies depending on time</li>
<li>several resource scripts (for <a href="/facts/Apache_HTTP_Server/tcmWYYUq">Apache</a>, <a href="/facts/IBM_Db2/2cYITuuY">IBM Db2</a>, <a href="/facts/Oracle_database/FHv5g732">Oracle</a>, <a href="/facts/PostgreSQL/LHdXuHfl">PostgreSQL</a> etc.) included</li>
<li><a href="/facts/Graphical_user_interface/wBlQFWDP">GUI</a> for configuring, controlling and monitoring resources and nodes</li></ul>
