I have a mongo 2 node cluster running, with this replica set config.
config = {_id: "repl1", members:[
{_id: 0, host: 'localhost:15000'},
{_id: 1, host: '192.168.2.100:15000'}]
}
I have to move these both nodes on to new servers. I have copied everything from old to new servers, but I'm running into issues while reconfiguring the replica config due to ip change on the 2nd node.
I have tried this.
config = {_id: "repl1", members:[
{_id: 0, host: 'localhost:15000'},
{_id: 1, host: '192.168.2.200:15000'}]
}
rs.reconfig(config)
{
"startupStatus" : 1,
"errmsg" : "loading local.system.replset config (LOADINGCONFIG)",
"ok" : 0
}
It shows above message, but change is not happening.
I also tried changing replica set name but pointing to the same data dirs. I am getting the following error:
rs.initiate()
{
"errmsg" : "local.oplog.rs is not empty on the initiating member. cannot initiate.",
"ok" : 0
}
What are the right steps to change the IP but keeping the data on the 2nd node, or do i need to recreate/resync the 2nd node?
