perfSONAR User Q&A and Other Discussion

[David Cohen <>]

Hi Ivan,

The system was installed from a PerfSonar installation image.

perfSONAR Toolkit v4.2.4-1.el7

CentOS Linux release 7.8.2003 (Core)

python-dateutil.noarch 1.5-7.el7

As I mentioned in my original email:

export PYTHONPATH=/usr/lib/python2.7/site-packages

resolves the problem by adding existing dateutil to the python search path.

Bets regards,

David

Hi David,

 

Please also tell what pS software are you running and what version on which OS.

We can only assume here about pS Toolkit on CentOS 7.x.

 

Please check if you have the required package:

 

‘yum list python-dateutil’

 

 

Regards,

Ivan Garnizov

Betreff: Re: [perfsonar-user] Using ps_remove_data.py

 

Hi Andrew,

. bin/activate

is now working but dateutil is still missing,

thee is also a typo in the instructions, a missing "/" in the beginning of conf file path.

 

[root@tech-ps ~]# cd /usr/lib/esmond/

[root@tech-ps esmond]# . bin/activate
(esmond)[root@tech-ps esmond]# python /usr/lib/esmond/util/ps_remove_data.py -c usr/lib/esmond/util/ps_remove_data.conf
Traceback (most recent call last):
  File "/usr/lib/esmond/util/ps_remove_data.py", line 94, in <module>
    import dateutil.parser
ImportError: No module named dateutil.parser

(esmond)[root@tech-ps esmond]#

 

Cheers,

David

What happens when you change your current working directory to  /usr/lib/esmond/ before running the script (i.e. cd  /usr/lib/esmond/)? Possible it is making assumptions about the python path relative to the current directory.

Hi,

Recently, I observed that the PerfSonar root partition is close to full.

Trying to use ps_remove_data.py as documented at:

ttps://docs.perfsonar.net/multi_ma_backups.html

 

Produced some django and dateutils couldn't be found errors.

That worked for me though:

 

source /usr/lib/esmond/bin/activate

export PYTHONPATH=/usr/lib/python2.7/site-packages

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

 

Best regards,

David
