Since the upgrade a couple of my toolkit servers are not getting their pscheduler tasks any more. Other servers in the mesh are fine. I fixed limits.conf on all of them. Here are the outputs on one of the problematic servers.

 

[root@ps-14-ldn-tele pscheduler.d]# psconfig remote list
…

      "url" : "http://perf-pwa.sanren.ac.za/pub/config/sanren_mesh_2019.json",

I don't see anything funny in the log files:

…

2023/04/21 12:35:08 INFO guid=2E4ED44A-E030-11ED-9B71-BCF47E5E890A action="create" msg=No tasks to create

 

I wasn’t able to pull the mesh from here (server refused connection), so I couldn’t look at it directly.  However, the fact that pSConfig didn’t find any tasks to create means:

 

• None of the addresses specified in the mesh matches the hostname or the IP or FQDN on one of its interfaces
• -OR- no group includes an address that matches the host
• -OR- no task refers to a group that refers to a matching address

 

If your other hosts made the transition without trouble, odds are good something else changed that made pSConfig unable to find a match.  If you want to send me the mesh privately along with the output of `ip a` on that host, I’ll have a look at it for you.

 

Thanks, by the way, for including all of the troubleshooting output.  That helps weed out a lot of potential problems.  We might see about adding checking for host matches to the troubleshooting procedure since that first item is a frequent cause of problems.  I’ve opened a ticket on that:   https://github.com/perfsonar/psconfig/issues/101
