perfSONAR User Q&A and Other Discussion

[Johann Hugo <>]

Hi all

I get a "password authentication failed for user "esmond"" in /var/log/esmond/django.log

I've stopped cassandra, moved the database, start cassandra

systemctl stop cassandra

mv /var/lib/cassandra/data/system /var/lib/cassandra/data/system.old

systemctl start cassandra

Do I need more steps to recreate the DB ?

I following the steps from https://docs.perfsonar.net/FAQ.html to nuke all data and start from scratch, but I get an error:

python /usr/lib/esmond/util/ps_remove_data.py -c esmond-nuke.conf

                                                             ^

Am I missing some steps here ?

BTW - The path for "configure_esmond" in the FAQ is different from my install.

/usr/lib/perfsonar/scripts/toolkit/system_environment/configure_esmond

should be:

/usr/lib/perfsonar/scripts/system_environment/configure_esmond
