Pinned topic Configure a default Cluster and FS manager

‏2012-08-23T09:19:25Z |
Hi all,
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.
Thx Bernd

    as long as you don't assign 'manager' designation to your NSD servers, they wont be elected as FS managers...

    mmchnode is your friend.

    Hallo 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.
    Regards Renar

    The 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.
