Bug 1010846

Can you check again that the bug exists on OSE 1.2? I cannot reproduce the problem:

  [root@broker ~]# rhc app create testapp2 ruby-1.9 postgresql -s --no-git
  Using postgresql-8.4 (PostgreSQL Database 8.4) for 'postgresql'

Additionally, the reported error message does not exist in Enterprise.  It was introduced in commit ee550b2e3700f9777b884c4814c337aecc4eb6db to origin-server, which has not been backported to enterprise-server, and the text 'Failed to correctly execute all parallel operations' does not appear anywhere in the Enterprise codebase (I did a git grep on the enterprise-1.2 and enterprise-1.2.z branches).

Can you bug the problem again on OSE 1.2 and provide the exact commands and output of those commands? If I could get access to a devenv where you have reproduced the bug, that would be even better.

For what it's worth, I do have a local branch with the backport of the fix from origin-server, ready to push and merge.

I have check it. We should create a non-scalable app to reproduce this problem.there is not this problem with a scalable app.

1.create an non-scalable app
#rhc app create xiaom3 ruby-1.9
2.add postgresql cartridge to it
#rhc cartridge add postgre -a xiaom3
3.stop the postgresql cartridge 
#rhc cartridge stop postgresql -a xiaom3
4.reload cartirdge 
#rhc cartridge reload postgresql -a xiaom3    
Using postgresql-8.4 (PostgreSQL Database 8.4) for 'postgresql'
