What was then called HA Summit was held in Brno, Czechia, on Feb. 4 and 5, 2015. The dates were chosen to coincide with the week of the DevConf conference to make it easier for people to attend. It was the first HA conference since 2008.

Some important milestones came out of the conference:

• ClusterLabs, which at the time focused solely on Pacemaker, was chosen as an umbrella location for open-source high availability clustering projects, to improve cooperation, coordination, and awareness
• The ClusterLabs IRC Channel and ClusterLabs Mailing Lists were created to replace multiple project-specific channels and lists
• Future summits would be called ClusterLabs Summits, with a goal of holding one every 2 to 3 years (which was met until the COVID-19 pandemic)

Various topics of open discussion included:

• Scaling with pacemaker-remoted and/or a new messaging/membership layer
• SBD (storaged based death) fencing
• Degraded mode for resource status
• Making fencing mandatory (or requiring a special setting waiving rights to complain if disabled)
• Scan Core is an open source effort to provide a mechanism for collecting and analysing software and sensor data and using it to make intelligent decisions about cluster configurations. The primary comment here was to explore the possibility of having Scan Core support existing nagios scan agents.
• Better support for SNMP to simplify management of large cluster environments
• UI / ease of use, cooperation and sharing ideas on improving the interfaces
• OCF standard updates: We now have a process for proposing changes to the OCF standard via pull requests on github. Marek Grac proposed adding features currently used by the fence-agents to the OCF standard, and krig proposed some form of parameter validation (types for IP address, file, directory, device, integer ranges, email address, executable, boolean, etc.) to improve the feedback given by UIs for incorrect data in parameters
• Requirements for development of resource agents for 3rd party applications from ISVs (for example SAP)
• Integration of CTDB/clustered Samba with Pacemaker
• Geo-clustering with booth
