Hi, all. I am new to Rocks but have set up a couple of Beowulf Linux clusters with Torque and Maui.
This time we bought the new cluster from the vendor and my senior manager wanted the vendor to save us time and have them installed Rocks 4.3 for us. Currently, Torque + Maui can not work together for a simple setup. #qmgr -c "print server" create queue default set queue default queue_type = Execution set queue default kill_delay = 90 set queue default enabled = True set queue default started = True # # Create and define queue batch # create queue batch set queue batch queue_type = Execution set queue batch resources_default.nodes = 1 set queue batch resources_default.walltime = 01:00:00 set queue batch enabled = True set queue batch started = True # # Set server attributes. # set server scheduling = True set server acl_host_enable = False ################################ set server managers = root at jupiter.mydomain.com set server operators = root at jupiter.mydomain.com ################################ set server default_queue = default set server log_events = 511 set server mail_from = adm set server query_other_jobs = True set server resources_default.walltime = 336:00:00 set server scheduler_iteration = 60 set server node_ping_rate = 300 set server node_check_rate = 600 set server tcp_timeout = 6 set server node_pack = False set server pbs_version = 2.1.8 ----- #grep -v ^# /opt/maui/maui.cfg RMPOLLINTERVAL 00:00:3 SERVERPORT 42559 SERVERMODE NORMAL #NOTE: the fqdn SERVERHOST Jupiter.Mydomain.com RMCFG[Jupiter.Mydomain.com] TYPE=PBS ADMIN1 maui root LOGFILE maui.log LOGFILEMAXSIZE 10000000 LOGLEVEL 3 QUEUETIMEWEIGHT 1 BACKFILLPOLICY FIRSTFIT RESERVATIONPOLICY CURRENTHIGHEST NODEALLOCATIONPOLICY MINRESOURCE ENABLEMULTINODEJOBS TRUE ENABLEMULTIREQJOBS TRUE ---- The information on /etc/hosts are the followings and _cannot_ be changed: ############################################ #cat /etc/hosts | grep Jupiter 10.1.1.1 Jupiter.local Jupiter # originally frontend-0-0 192.168.10.181 Jupiter.Mydomain.com ############################################ The compute nodes are in 10.1.1.0/8 network. As you can see SERVERHOST and RMCFG domain name's first letter (Mydomain) is capitalized and if I changed it to Jupiter.mydomain.com or jupiter.Mydomain.com or jupiter.mydomain.com or Jupiter.local or Jupiter then I would get this type of error: Starting maui: ERROR: server must be started on host 'jupiter.Mydomain.com' (currently on 'Jupiter.Mydomain.com') ---- I would like to know where is this "(currently on 'Jupiter.Mydomain.com')" being set. Currently, I could only set these 2 parameters to Jupiter.Mydomain.com but doing so Maui would only listen to the public interface and torque pbs can not communicate with maui to schedule job Jupiter PBS_Server: Connection refused (111) in contact_sched, Could not contact Scheduler - port 15004 If I modified /etc/hosts to have "10.1.1.1 Jupiter.Mydomain.com" then torque and maui would work but after I rebooted the frontend then this manually set entry got overwritten by the info in the database. I used php admin interface and would like to change that value but an engineer from the vendor told me that I should not change that entry because that is the way rocks works. Please advise what I should modify to make maui listen to private interface or non FQDN so torque can communicate with it. Thank you very much for your helps.
