Description scollier 2012-06-13 13:59:40 UTC

Description of problem:

When the audrey agent launches it gives this error message:

# cat /var/log/audrey.log 
2012-06-13 14:45:07,425 - ERROR   : audrey:93 Failed accessing RHEVm user data.


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

# rpm -qa | grep audrey
aeolus-audrey-agent-0.4.5-1.el6.noarch

The hypervisor is:
RHEL - 6Server - 6.2.0.3.el6
VDSM Version - 3.0.112.1

How reproducible:

Sometimes.  Not always.  Sometimes it works.

Steps to Reproduce:
1. Launch a instance that has a <services> element in the app blueprint
2.
3.
  
Actual results:
 fails with above message

Expected results:
accesses user data, contacts config server and runs scripts.

Additional info:


I see it probably 10-20% of launches.

Comment 1 scollier 2012-06-14 01:20:18 UTC

I upgraded the RHEV environment to 3.0.3 today.  I just received the error again when launching to the RHEV environment:


# cat /var/log/audrey.log 
2012-06-14 02:21:47,611 - ERROR   : audrey:93 Failed accessing RHEVm user data.

Comment 2 dgao 2012-06-14 14:03:33 UTC

This bug is caused by:

https://bugzilla.redhat.com/show_bug.cgi?id=831577

which is introduced by applying a bad patch that fixes 

https://bugzilla.redhat.com/show_bug.cgi?id=796528.

Closing this bug because it's not an audrey agent issue.

Comment 3 Jan Provaznik 2012-06-19 13:00:32 UTC

I don't think this is caused by 831577 because:
1) a patch for 831577 was pushed only to 1.0.1 branch (fix of this regression - 796528 - is already in 1.0.1 too), but AFAIK Scott used 1.0.0
2) the problem occurs in 10%-20%, the regression introduced by 831577 caused failure in 100%

Re-opening this bug - a problem is somewhere else.

Comment 4 Joe Vlcek 2012-06-19 20:03:54 UTC

I have a patch in the works. Testing has been successful.

Comment 6 Joe Vlcek 2012-06-20 17:07:39 UTC

commit d66ec3793fab6ce58f48369289b03f378903a606

Comment 7 Joe Vlcek 2012-07-27 13:54:40 UTC

The fix for this bug has been pushed and confirmed by QA.

Why is it still open?

Comment 8 dgao 2012-08-06 15:29:15 UTC

Closing as this is no longer reproducible.
