perfSONAR User Q&A and Other Discussion

[Michael Petry <>]

Only one process running when I looked, but this was straight off the ISO behavior.   That was my concern.  There may be a synchronization issue hidden in the startup scripts/configs.

The cassandra log shows:

/usr/sbin/cassandra: line 155: /var/run/cassandra/cassandra.pid: No such file or directory

and there is no /var/run/cassandra

Looks like something in the setup on the ISO needs tweaking.

Hi Mike,

Do you already have an instance of cassandra running? I have seen similar cases where you "start" cassandra on a machine where it's still running, particularly where the pidfile gets out of sync and so the init scripts think things are okay.

You may want to look at something like `ps aux | grep cassandra` and kill any existing processes that may be running, that start again via the init script.
