perfSONAR User Q&A and Other Discussion

[Jason Watt <>]

Mark,

   Thanks!  Your mention of "prior version" led to discovering I had at some point disabled the perfsonar repo.  The system I was having an issue with had these versions:

perfsonar 4.1.6-1.el7
python-urllib3              1.10.2-7.el7

CentOS Linux release 7.7.1908  

After enabling the perf repo and updating to 4.2.1, the problem went away.

Thanks again,

Jason

Has anyone come across this problem with perf before?  Just about any pscheduler command produces these errors, and archiving quit working.  Here is the last portion of pscheduler troubleshoot:

 

/usr/lib/python2.7/site-packages/urllib3/connectionpool.py:769: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.org/en/latest/security.html
  InsecureRequestWarning)
 Failed.
Archiving never completed.

 

The error message you’re seeing is produced by urllib3, which underpins Python’s requests library.  We replaced that with libcURL in 4.2.0.

 

If you’re running a prior version, can you let me know what OS you’re running and check what version of python-urllib3 is installed on your system?  There was a change in urllib3 1.25 (released in September) that made it pickier about self-signed certificates, which is what the pScheduler server uses.  I’m not seeing that CentOS, EPEL or Debian has upgraded that far, so I’m a little curious about how  that version got onto your system.
