Probe hosts error screenshot

Description of problem:
Probe hosts in Cockpit UI fail with error "Unexpected playbook failure. Check ansible-runner-service directory '2dcbb7ee-b4c4-11ea-aff0-002590fbd652' for details" as shown in the attachment and hence could not proceed with the installation.

Also, logs are not available in ansible-runner-service directory as the error shows

Version-Release number of selected component (if applicable):

cockpit-ceph-installer-1.1-0.el7cp.noarch

Also, I had added a metrics node as you can see in the attachment but in next validate step it went missing any idea why this happened?( you can compare attachment 1698351 [details])
Comment 2 Paul Cuzner 2020-06-22 23:09:46 UTC 
issue relates to EOL py2 support. The probe trips up detecting the disk signature gpt or mbr since it was using py3 only syntax - the Ameena's test environment is RHEL7 + py2.

fix on upstream branch ready for testing (fix-gpt-detection-py2)

Comment 4 Paul Cuzner 2020-06-24 00:23:03 UTC 
Tested patch on the QE systems directly (minor py change)

- all hosts have py2 as the default python interpreter
- cockpit UI launched, and installer flow started using the existing server:role layout
- probe performaned successfully (see attachment)

Ameena, please confirm. Once confirmed, I'll merge the change and get the rpm rebuilt.

Hi Paul,
I have tested the patch and the probe host issue is not seen.
