Hi all,

I have a perfSONAR toolkit which had iperf 3.1.7 and I updated it manually to
3.9 (uninstalled 3.1.7, then downloaded 3.9 from
https://downloads.es.net/pub/iperf/).

I can run iperf3 on that server (located at /usr/bin/ with the same
permissions other tools like traceroute, nuttcp, etc have) but pScheduler
doesn't seem to find it. When I run a throughput test with '--tool iperf3',
for example:

"pscheduler task --tool iperf3 throughput --dest psb01-gva.cern.ch"

I get:

"Failed to post task: Unable to complete request: No tool in common among the
participants: localhost offered nuttcp, iperf2, ethr; psb01-gva.cern.ch
offered iperf3, nuttcp, iperf2, ethr."

Without the --tool option it works fine but uses nuttcp. From what I've seen
on the logs, a SQL database is queried to check what tools are available on
the node.
How can I update that DB? I tried these two but didn't fix the problem:

sudo pscheduler internal db-update
sudo yum reinstall pscheduler-server

Many thanks in advance.

Regards,
Ignacio
