Highlights

Features added since Pacemaker-1.1.10

• crmd: Do not block on proxied calls from pacemaker_remoted
• crmd: Enable cluster-wide throttling when the cib heavily exceeds its target load
• crmd: Make the per-node action limit directly configurable in the CIB
• crmd: Slow down recovery on nodes with IO load
• crmd: Track CPU usage on cluster nodes and slow down recovery on nodes with high CPU/IO load
• crm_mon: add --hide-headers option to hide all headers
• crm_node: Display partition output in sorted order
• crm_report: Collect logs directly from journald if available
• Fencing: On timeout, clean up the agent's entire process group
• Fencing: Support agents that need the host to be unfenced at startup
• ipc: Raise the default buffer size to 128k
• PE: Add a special attribute for distinguishing between real nodes and containers in constraint rules
• PE: Allow location constraints to take a regex pattern to match against resource IDs
• pengine: Distinguish between the agent being missing and something the agent needs being missing
• remote: Properly version the remote connection protocol
