Hi everyone, I’m adding a new node to an existing cluster. After installing slurm and the prereqs, I synced the clocks with ntpd. When I run ‘ntpq -p’, I get 0.0 for delay, offset and jitter. (the slurm head node is also the ntp server) ‘date’ also gives me identical times for the head and compute nodes. However, when I start slurmd, I get a munge error about the clocks being out of sync. From the slurmctld log:
[2020-10-27T11:02:06.511] node NEW_NODE returned to service [2020-10-27T11:02:07.265] error: Munge decode failed: Rewound credential [2020-10-27T11:02:07.265] ENCODED: Tue Oct 27 11:09:45 2020 [2020-10-27T11:02:07.265] DECODED: Tue Oct 27 11:02:07 2020 [2020-10-27T11:02:07.265] error: Check for out of sync clocks [2020-10-27T11:02:07.265] error: slurm_unpack_received_msg: MESSAGE_NODE_REGISTRATION_STATUS has authentication error: Rewound credential [2020-10-27T11:02:07.265] error: slurm_unpack_received_msg: Protocol authentication error [2020-10-27T11:02:07.275] error: slurm_receive_msg [HEAD_NODE_IP:PORT]: Unspecified error I restarted ntp, munge and the slurm daemons on both nodes before this last error was generated. Any idea what’s going on here?
