perfSONAR User Q&A and Other Discussion

Hi Soichi.

After running 'rm -rf /var/lib/pgsql/data/*' try stopping postgresql with "/sbin/service postgresql stop" then proceeding with the rest of the commands. My guess would be the postgresql is already running and still has the old password loaded. 

Thanks,

Andy

Hello.

I am having the same problem on perfsonar-bw.grid.iu.edu.

When I run configure_esmond, it asks me for password,

[root@perfsonar-bw ~]# rm -rf /var/lib/pgsql/data/*                                       

[root@perfsonar-bw ~]# /opt/perfsonar_ps/toolkit/scripts/system_environment/configure_esmond
Initializing database:                                     [  OK  ]
Starting postgresql service:                               [FAILED]
Waiting for postgresql to complete startup
could not change directory to "/root"
Password:

 I don't know what password it is asking.. what password should I enter here?

Yes it will delete your data. On the flip side, if you have collected data then you shouldn't have this problem unless you are really just trying to mess with me  :)

To anyone else reading this thread, in general, please do not run these commands. Under normal circumstances you shouldn't have to. If you have no data in the graphs as indicated in the subject there is a very high chance its something else entirely. Please contact the list with information about your specific case if you are unsure.
