is there a way to configure a default FS and cluster manager (mmchconfig mmchfs)? I would like to make sure that the FS manager does not reside on NSD servers since they are very busy serving I7O.

Re: Configure a default Cluster and FS manager2012-08-23T16:08:37Z in response to SystemAdminHallo Bernd,
the first gpfs-node that is defined as managernode that is started is the cluster-manager. If you want to change these selection you must change this with mmchmgr -c. You can also dynamicaly change the filesystemmanager with these cmd after the election as fs-manager on this node. My understanding here the first manager node in the list of managernode is elected as FS-Manager.

Re: Configure a default Cluster and FS manager2012-08-23T16:18:26Z in response to SystemAdminThe cluster manager is selected from the pool of quorum nodes -- typically the first node in the list that's up would be elected. The file system manager is appointed from the pool of nodes with the 'manager' designation; if none exist, the quorum nodes are used. So have a pool of quorum and manager nodes, and make sure your NSD servers aren't in that pool.
