Hi I'd like to discuss redundancy type in pacemaker of course I read this one: http://clusterlabs.org/doc/en-US/Pacemaker/1.1-plugin/html/Clusters_from_Scratch/s-intro-redundancy.html
BUT i'm wondering if it possible to make such SCENARIO let's say we have 2 locations (A and B) we have 4 servers (2 per location) or 3 servers (2 in A, 1 backup in B) location A is primary, location B acts as backup - so it should only be active ONLY during blackout of A on location A - we want to have active-active service (lets say it's IP address) running on both servers ... if one server in location A goes down... the service doesn't go to backup server in location B - but it remains in location A (so it stays only on 2nd server in A) whole location A goes down - active-active service is migrated to location B (in fact it doesn't need to be active-active in B - it's enough if it works on one server in B) i hope my description is clear enough :) I was trying to play with some options but I couldn't do it as designed.... i could do active-active (but when one fails - service was active-active on 1 server in A and 1 server in B) regards, n
