perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

A couple things to check: are you a sudo user when you do this? are you using bash as your shell (the command before it in particular assumes bash)? any errors from the prior command "source /opt/rh/python27/enable”?

Thanks,

Andy

Yes but when I do I also get an error when I enter:

 

/opt/rh/python27/root/usr/bin/virtualenv --prompt="(esmond)" .

 

The error is:

 

/opt/rh/python27/root/usr/bin/python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

Subject: Re: [perfsonar-user] Removing old Cassandra Data

 

Andreas,

 

Have you done the following before attempting to run the ps_remove_data?

 

cd /usr/lib/esmond

source /opt/rh/python27/enable

/opt/rh/python27/root/usr/bin/virtualenv --prompt="(esmond)" .

. bin/activate

 

From here: http://docs.perfsonar.net/multi_ma_backups.html

 

esmond uses a nonstandard python (2.7) on CentOS6, so the environment must be set up correctly for its various scripts to run correctly, otherwise it may try to run under python 2.6 and get incorrect behavior.

Hi,

 

I’m trying to remove old measurement data from perfsonar, and I try running this command:

 

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

 

but I get this error:

 

Traceback (most recent call last):

  File "/usr/lib/esmond/util/ps_remove_data.py", line 69, in <module>

    import django

ImportError: No module named Django

 

Can you help with this?

 

Kind Regards,
