Changing Default LIM Behavior to Improve Performance Reconfiguration and LSF_MASTER_LIST If you change LSF_MASTER_LIST Whenever you change the parameter LSF_MASTER_LIST, reconfigure the cluster with lsadmin reconfig and badmin mbdrestart. If you change lsf.cluster.cluster_name or lsf.shared If you make changes that do not affect load report messages such as adding or removing slave-only hosts, you only need to restart the LIMs on all master candidates with the command lsadmin limrestart and the specific host names. For example: % lsadmin limrestart hostA hostB hostC If you make changes that affect load report messages such as load indices, you need to restart all the LIMs in the cluster. Use the command lsadmin reconfig. How LSF works with LSF_MASTER_LIST LSF_MASTER_LIST undefined In this example, lsf.shared and lsf.cluster.cluster_name are shared among all LIMs through an NFS file server. The preferred master host is the first available server host in the cluster list in lsf.cluster.cluster_name. Any slave LIM can become the master LIM. Whenever you reconfigure, all LIMs read lsf.shared and lsf.cluster.cluster_name to get updated information. For this example, slave LIMs read local lsf.conf files. lsf.shared lsf.cluster.cluster_name HostB Master LIM HostC lsf.conf slave LIM HostD lsf.conf slave LIM HostE lsf.conf slave LIM HostF lsf.conf slave LIM HostG lsf.conf slave LIM HostH lsf.conf LSF_MASTER_LIST defined The files lsf.shared and lsf.cluster.cluster_name are shared only among LIMs listed as candidates to be elected master with the parameter LSF_MASTER_LIST. The preferred master host is no longer the first host in the cluster list in lsf.cluster.cluster_name, but the first host in the list specified by LSF_MASTER_LIST in lsf.conf. 488 Administering Platform LSF
Chapter 37 Tuning the Cluster Whenever you reconfigure, only master LIM candidates read lsf.shared and lsf.cluster.cluster_name to get updated information. The elected master LIM sends configuration information to slave LIMs. The order in which you specify hosts in LSF_MASTER_LIST is the preferred order for selecting hosts to become the master LIM. lsf.shared lsf.cluster.cluster_name hostB Master LIM hostC lsf.conf master LIM candidate hostD lsf.conf master LIM candidate hostE lsf.conf slave-only LIM hostF lsf.conf slave-only LIM hostG lsf.conf slave-only LIM hostH lsf.conf LSF_MASTER_LIST=hostC hostD hostE Considerations LSF_MASTER_LIST undefined Generally, the files lsf.cluster.cluster_name and lsf.shared for hosts that are master candidates should be identical. When the cluster is started up or reconfigured, LSF rereads configuration files and compares lsf.cluster.cluster_name and lsf.shared for hosts that are master candidates. In some cases in which identical files are not shared, files may be out of sync. This section describes situations that may arise should lsf.cluster.cluster_name and lsf.shared for hosts that are master candidates not be identical to those of the elected master host. When LSF_MASTER_LIST is not defined, LSF rejects candidate master hosts from the cluster if their lsf.cluster.cluster_name and lsf.shared files are different from the files of the elected master. Even if only comment lines are different, hosts are rejected. A warning is logged in the log file lim.log.master_host_name and the cluster continues to run, but without the hosts that were rejected. If you want the hosts that were rejected to be part of the cluster, ensure lsf.cluster.cluster_name and lsf.shared are identical for all hosts and restart all LIMs in the cluster with the command: % lsadmin limrestart all Administering Platform LSF 489
