While your storage nodes are starting up, you can get slightly more detailed information about what they are doing via the management client.
If you enter STATUS, the management client will tell you what phase of the startup process you are in, as in this example:
ndb_mgm> 2 STATUS Node 2: starting (Phase 2) (Version 5.0.11) ndb_mgm> 2 STATUS Node 2: started (Version 5.0.11)
You can also use the ALL STATUS command to list the status for all nodes at the same time.
A quick description of what the cluster is doing during each phase follows; this is often useful when you are debugging problems as it gives you a hint as to exactly what problems you are experiencing:
