Thanks Todd, I did it and … still jobs do not start. This is new content of the relevant part of /etc/condor/condor_config.local ############################################################################### # Security settings ############################################################################### # Allow local host and the central manager to manage the node ALLOW_ADMINISTRATOR = $(FULL_HOSTNAME), $(CONDOR_HOST) # master needs this two particular versions ALLOW_READ = *.lns.mit.edu,10.200.60.* ALLOW_WRITE = *.lns.mit.edu,10.200.60.* # Fix to version 8.3.6 suggested by ToddL ALLOW_NEGOTIATOR = 10.200.60.* ALLOW_NEGOTIATOR_SCHEDD = 10.200.60.* ############################################################################### At 15:38 I made this change on IP=121 which is condor master and has 6 job-slots open. I executed service condor restart next submitted 12 jobs - all are idle, despite 14 jobs slots are open. At 15:42 I made similar change on IP=122, which is just condor worker node. I did not expected it changes anything since the change on IP=121 did not helped. To be absolutely sure I rebooted few minutes later both VMs and verified again, condor jobs do not start, despite 6+8 jobs slots are open. Perhaps you can find time to look again in to the log files, which are copied from both VMs : $ scp -rp root@xxxxxxxxxxxxxxxxxxxx:/var/log/condor condor-122 $ scp -rp root@xxxxxxxxxxxxxxxxxxxx:/var/log/condor condor-121 and posted them here: Thanks for looking in to it Jan |
