Description Zhe Wang 2013-07-22 09:27:19 UTC 
Description of problem:
Given a scaling app with auto scaling disabled, it fails to add a Jenkins-client cartridge to it after scaling it up. On the other hand, there is no such problem if we do not scale up the app before adding Jekins-client cartridge.

Version-Release number of selected component (if applicable):
devenv_3535

How reproducible:
always

Steps to Reproduce:
1. create a scaling app

2. disable its auto scaling by touching a disable_auto_scaling marker

3. push the marker to its repo

4. scale up the app with REST API

5. create a Jenkins server app

6. embed a Jenkins-client cartridge to this app

7. check the gear groups of this app via REST API

Actual results:
Adding a Jenkins-client cartridge to the scaled up app fails with the error below:

Using jenkins-client-1.4 (Jenkins Client 1.4) for 'jenkins-client'
Adding jenkins-client-1.4 to application 'srb9' ... Unexpected error: User does not exist in cgroups: 447847664739953338744832

Moreover, in Step 7, it turns out that the UUID in the error in Step 6 referrs to the scaled-up gear.

Expected results:
It should be successful to add a Jenkins-client cartridge to a scaled app.

The bug has been fixed in devenv_3574, and the steps are identical to those in the description.

Result:

[zhe@fedora run106]$ rhc cartridge add jenkins-client -a spy27
Using jenkins-client-1.4 (Jenkins Client 1.4) for 'jenkins-client'
Adding jenkins-client-1.4 to application 'spy27' ... done

jenkins-client-1.4 (Jenkins Client 1.4)

Would you please move this bug to ON_QA, so that I can archive this bug as VERIFIED then.

Thanks,
