perfSONAR User Q&A and Other Discussion

[Andreas Demetriou <>]

 

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

 

Thanks,

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,
