I have a manager node contains collector and negotiator. It has "htcondormanager" DNS address in my network. Sometimes this node can reboot with a new IP address. My execute and submit nodes contains the following setting:
CONDOR_HOST = htcondormanager
But when the manager node is restarted with its IP address change (from 172.17.0.22 to 172.17.0.24), the startd and schedd nodes can no longer connect to the collector with errors:
ERROR: SECMAN:2003:TCP connection to collector htcondormanager failed.
Failed to start non-blocking update to <172.17.0.22:9618
attempt to connect to <172.17.0.22:9618
> failed: No route to host (connect errno = 113).
It turns out that nodes get IP once from the "htcondormanager" address at the start.
How can I tell Condor to resolve DNSÂevery 10 minutes?
