hi people: I pretend to build a HA cluster using Heartbeat with 2 nodes (Active/Standby). These nodes are just compatible computers (PCs), so they don't have any IPMI, RSA, APC or similar features to use stonith. I'm thinking about using DRBD to replicate information between both nodes so I would like someone with more experience than me give me some advices to achieve a reliable setup. - If I won't be able to use stonith to kill the other node in split brain situation... Does my information will be at risk? - If I use a dual-primary DRBD configuration... Is it possible that data loss occurs in split brain situations? Do I need to use GFS/OCFS in this scenario? How reliable is this for production use= - What would be that appropiate shared storage configuration for my HA Cluster? I have seen some posts talking about DRBD+NFS or DRBD+iSCSI.. How reliable are the alternatives that I have? I'm trying to make the right choice of technologies for my cluster scenario so I would appreciate some advices. Please consider my ONLY TWO PCs available (both nodes), or maybe suggest me a better scenario (maybe a third PC or something else) so I can evaluate the better choice. Thanks people , bye :)
