i like to verify things.
Over private network,public network(if is setup the llt traffic) or disk hearbeat go heart beat and gab traffic(when a resource is modifed,added).
Let`s say we have 2 nodes vcs and the service group failover from noda a to node b.What happened and what happens?The agent of faulty resource put the resource offline,HAD interogate this agent and saw the resource offline and is a critical resource,then had start to put the group offline on this node.So at every resource put offline,had will log in engine_A.log and will send out through gab the information that a certain resource is offline on node a.On node b the gab will receive this and will inform had about it.This had will modify it in RAM and will log in engine_A.log.right?
The same steps to all the resources within this group and with group itself.
On node b then had will start the group based on information from main.cf.So every agent will bring online the appropiate resource and had will write into engine_A.log.Example,the diskgroup agent will import the disk group and will start the volumes,then monitor this disk group.right?
Every time when an resource is added or modified on an node,had on that node will write this information on main.cf and log it,then will send out using gab to the other vcs nodes.right?
Please i like to verify also when i should to use gabconfig -c -x.Is this when i have 3 nodes cluster and 1 node goes down,or 2 nodes clusters and 1 node goes down?
thanks so much.
