BDA Expansion Fails with Error Illegal Number of Nodes on Rack
(Doc ID 2107177.1)
Last updated on MARCH 24, 2016
Applies to:Big Data Appliance Integrated Software - Version 4.2.0 and later
The symptom is that it is not possible to expand the cluster by a number other than multiples of 3 nodes. Doing so results in a failure. The Mammoth log files show the following error:
GridSteps::DieTrap('Exiting...') called at GridSteps.pm line 1532
GridSteps::MsgPrint('EE', 'Cannot continue with operation') called at GridSteps.pm line 13668
GridSteps::ValidateParamfile() called at /opt/oracle/BDAMammoth/bdaconfig/GridInst.pl line 151
GridSteps.pm line 13668 corresponds to :
if ($appl_node_count[$idx] < 3)
MsgPrint("E", "Illegal number of nodes on rack $racklist[$idx]");
MsgPrint("EE", "Cannot continue with operation");
