Controlling mbatchd Controlling mbatchd Restarting mbatchd When you reconfigure the cluster with the command badmin reconfig, mbatchd is not restarted. Only configuration files are reloaded. If you add a host to a host group, or a host to a queue, the new host is not recognized by jobs that were submitted before you reconfigured. If you want the new host to be recognized, you must restart mbatchd. Run badmin mbdrestart. LSF checks configuration files for errors and prints the results to stderr. If no errors are found, the following occurs: ◆ Configuration files are reloaded. ◆ mbatchd is restarted. ◆ Events in lsb.events are reread and replayed to recover the running state of the last mbatchd. Whenever mbatchd is restarted, it is unavailable to service requests. In large clusters where there are many events in lsb.events, restarting mbatchd can take some time. To avoid replaying events in lsb.events, use the command badmin reconfig. Logging a comment when restarting mbatchd Use the -C option of badmin mbdrestart to log an administrator comment in lsb.events. For example, % badmin mbdrestart -C "Configuration change" The comment text Configuration change is recorded in lsb.events. Use badmin hist or badmin mbdhist to display administrator comments for mbatchd restart. Shutting down mbatchd 1 Run badmin hshutdown to shut down sbatchd on the master host. For example: % badmin hshutdown hostD Shut down slave batch daemon on .... done 2 Run badmin mbdrestart: % badmin mbdrestart Checking configuration files ... No errors found. This causes mbatchd and mbschd to exit. mbatchd cannot be restarted, because sbatchd is shut down. All LSF services are temporarily unavailable, but existing jobs are not affected. When mbatchd is later started by sbatchd, its previous status is restored from the event log file and job scheduling continues. 64 Administering Platform LSF
Reconfiguring Your Cluster Chapter 3 Working with Your Cluster After changing LSF configuration files, you must tell LSF to reread the files to update the configuration. The commands you can use to reconfigure a cluster are: ◆ lsadmin reconfig ◆ badmin reconfig ◆ badmin mbdrestart The reconfiguration commands you use depend on which files you change in LSF. The following table is a quick reference. After making changes to ... Use ... Which ... hosts badmin reconfig reloads configuration files lsb.hosts badmin reconfig reloads configuration files lsb.modules badmin reconfig reloads configuration files lsb.nqsmaps badmin reconfig reloads configuration files lsb.params badmin reconfig reloads configuration files lsb.queues badmin reconfig reloads configuration files lsb.resources badmin reconfig reloads configuration files lsb.users badmin reconfig reloads configuration files lsf.cluster.cluster_name lsadmin reconfig AND badmin mbdrestart reconfigures LIM, reloads configuration files, and restarts mbatchd lsf.conf lsf.shared lsadmin reconfig AND badmin mbdrestart lsadmin reconfig AND badmin mbdrestart Reconfiguring the cluster with lsadmin and badmin 1 Log on to the host as root or the LSF administrator. 2 Run lsadmin reconfig to reconfigure LIM: % lsadmin reconfig Checking configuration files ... No errors found. reconfigures LIM and reloads configuration files, and restarts mbatchd reconfigures LIM, reloads configuration files, and restarts mbatchd lsf.sudoers badmin reconfig reloads configuration files lsf.task lsadmin reconfig AND reconfigures LIM and reloads badmin reconfig configuration files Do you really want to restart LIMs on all hosts? [y/n] y Restart LIM on ...... done Restart LIM on ...... done Restart LIM on ...... done The lsadmin reconfig command checks for configuration errors. If no errors are found, you are asked to confirm that you want to restart lim on all hosts and lim is reconfigured. If fatal errors are found, reconfiguration is aborted.
