Thanks in advance for your help. I am using HPC R2 pack installed on 2008 R2 machine acting as head node, I had compute node HPCCN01-07 added to cluster & everything working fine. Because of some hardware failure I was in need to replace two of my nodes HPCCN03 & HPCCN07. I deleted both nodes from HPC server manager GUI & operation went successful. NOw I am trying to add two different machine with same hostname to the headnode as preconfigured compute nodes, the operation is failing with following errors in provisioning logs :
Failed to update the scheduler configuration. The node with name HPCCNO7 already exists.
Any ideas how to get past this errors.
Already tried but no help. However on head node I reinstalled the cluster manager software and now I am able to add all the nodes. I believe the cluster manager keeps a backup of information somewhere and when it is trying to update that it failed. It would be good to know about such details. Otherwise whenever a problem occurs always reboot or reinstallation is not feasible.
Yes, thats a problem. HPC pack tracks information about its state and all of nodes. Sometimes, for example, as in your situation, it can produce an error. Sad, but i didnt find a solution for such a problems. But i'll ask some people who may know. Because reinstalling of whole bunch of stuff when such an error occurs, is no good..
