From The HA Trenches

This is to serve as a retrospective hub over the field of HA in general, incl. for instance scenarios where pacemaker took a role, not necessarily positive:


 * GitHub/2012: multi-role MySQL, pacemaker and it's segfault


 * GoCardless/2017: Postgress, pacemaker, default-resource-stickiness, partial resource crash (via Adam Spiers on the users ML)
