Backup job not running on one node

[vtmikel]

Hello-

I have a fairly simple PBS backup job setup on my two node cluster. All nodes, all vms/lxc, nightly at 3am. Storage is PBS.

Recently I noticed that the backup job is not running on one of my nodes. Nothing of interest on syslog for the node that isn't executing the backup job at the time that it should run.

Manually running the job, runs on all nodes, as expected.

I removed the job, re-created. Still not running as scheduled.

Sorry for lack of logs, I just do not know where to look for signs of the problem. Any thoughts?

Hi,

I would check if the cron service running on that node:

systemctl status cron.service

Thanks for the response. Unfortunately (or fortunately), it is running.

This output is from the mentioned node right?

Can you please provide us with the syslog when the backup start until the backup job finish? You can get the syslog using journalctl by the following command:

journalctl --since '2024-08-20 00:00:00' --until '2024-09-20 09:20:00' > /tmp/Syslog.txt

You may edit date/time in the above command.

@Moayad - Thanks again for the response. Before seeing your response, I rebooted that node. After doing so, the backup job started launching at the scheduled time again. I’ll keep an eye on it and see if the situation reoccurs.

Thanks for the help.
