On client nodes (the ones that you want to monitor) you have edg-fmon-agent running. On the collector node you have 2 more proceses: edg-fmon-server and gridice-mds. If you want to move the collector you have to stop this 2 processes, and chkconfig --del <them>. A new configure_node will take care of some configuration files but won't stop this 2 processes. > 2) does YAIM remove RPMs no longer needed in the process of > configure/install of a node ?

Until now gridice packages didn't have any conflicts. > 3) does YAIM at least chkconfig --del <unwanted_services> ? > No - unfortunatelly you have to do as you say below. > I would do such changes by hand, thank you very much, :-) , provided > that somebody answers (1)... > > All the Best, Cristina PS: in case of more problems with gridice - there is [log in to unmask] > Sergio Andreozzi wrote: > >> Hi Laurence, >> >> Laurence Field wrote: >> >>> The reason for this decision was to make things more uniform. >>> >>> MON in this case is short for Monitoring.
