Description Peter Vreman 2019-07-17 09:10:59 UTC

Description of problem:
On RHEL6 the default is not to use cgroups.
The new Egg 3.0.110 has a check for cgroups

Running the Egg on RHEL6.10

--------

This is a major regresssion with the past. You should not require to add a new cofniguration setting to get things working on a OS release where the client was working before for years.


See the offical RHEL6 documentation https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/resource_management_guide/ch-using_control_groups#The_cgconfig_Service that the cgroup is an optional that is not part of the Base OS installation.


Add OS detection for RHEL6 to implciltyl set ignore_cgroup=True so it works again out of the box


Please also provide an explanation Why Engineering and Testing did not found this issue as it is major Regression on a well known standard platform.

Comment 1 Jeff Needle 2019-07-17 11:58:18 UTC

My apologies, Peter.  This was a complete and total process breakdown on our part in our coordination, testing, and release gating processes.  We have reverted that change and a new egg will be available very soon (within the hour, it is propagating now).  We will be addressing the QE failure and make immediate changes.  This was inexcusable on our part.

Comment 2 Ian Page Hands 2019-07-17 12:19:25 UTC

Peter please accept another apology from myself. This was a fix that was meant to address an issue where certain customers were experiencing a client failure when cgroups was partially disabled. This was a P1 for those customers.

Obviously there was a bug and this affected a wider audience.

The new egg is going out now but I believe you will have to manually force an egg update. Or tweak the setting and then the egg will update. Unfortunately this check happens before the egg is updated on the machine I believe.

I think you do done of these:
- https://access.redhat.com/articles/3747741
- rm /var/lib/insights
- set ignore_cgroup=True in /etc/insights-client/insights-client.conf then run the client, then remove it

Comment 3 Peter Vreman 2019-07-18 13:20:31 UTC

Good to read that you have identified it as a missing part of the QE process.

I am not really affected by it as i have auto_update=False. I had only to revert my last commit, because i thought the egg was successful as the first run (in which the new egg is downloaded) was successful

Only then when looking for the output of a new feature to print the egg versions (based on a diff of the unpacked egg source code i found this feature was developed) i noticed it failed to start on RHEL6.10

Many Thanks for seeing the issue being picked up quickly.

Comment 4 Peter Vreman 2019-07-19 14:39:35 UTC

Confirmed egg 3.0.112 fixes the issue
