I've set this up before but I`m getting stuck with the 5.11beta version.

Getting back 2 my own setup.. It seems like I was a bit impatient to see the nodes started.

I can now see both nodes on my setup , altough it looks like this only happens after I started an ndbd node.

But the I can't connect to the local management console on the second node without a -c parameter.

I guess I`ll log that as a bug.

2 management nodes, 2 data nodes .. (config details below)

I can launch both management nodes but when I try connectiong to the management console on the 2nd node it fails with the following error

NDB Cluster Management Server. Version 5.1.11 (beta) Id: 2, Command port: 1186 Unable to connect to our own ndb_mgmd (Error -1) This is probably a bug.

I can connect from a remote node to both nodes and they give different outputs.

It seems the second node is in som kind of Identity crisis :)

Is this a known bug , or did I forget something in my setup ?

Also when starting the 2nd node I only get a message in the 1st node's log file stating

But no further info on successful connects.
