When I started the PBS service, all daemon processes took tens of seconds to identify the network interface, for example pbs_server daemon, 13:52:34 – > 13:52:54 takes 20 seconds (similar to other comm, mom and sched)
02/07/2022 13:52:34; 0002; Server@cf -poc-master; Svr; Log; Log opened
The blank space is caused by copy and paste.
I confirmed that the configuration in /etc/hosts is the same as /etc/pbs.conf about cf-poc-master
I did the following tests:
Maintain offline status. execute command “getent hosts cf-poc-master” also takes about 20 seconds, which is equal to the time spent identifying the interface when PBS’s every daemon starts
Change the server online, then both command “getent hosts cf-poc-master” and pbs start are completed instantly
command “getent hosts cf-poc-master” outputs IPv6 address not IPv4 address. I think this is another problem, no need to care here.
In addition, command “getent ahost cf-poc-master” can instantly get the IPv4 address, no matter online or offline
Q: How can I further locate the DNS problem? Thank you!!!
