Description Rob Millner 2012-03-29 23:12:05 UTC

Description of problem:
All my test migrations fail on an mcollective error:

MCollective::UnknownRPCError: Failed to validate namespace: undefined method `match' for nil:NilClass


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


How reproducible:
Always


Steps to Reproduce:
1. Create a stage instance from the previous version of Express (ami-0fce1066)
2. Create several applications with and without jenkins
3. Edit the readme file on each app, push and observe the app updated successfully.
4. Switch to the yum "candidate" repositories, do a clean all and upgrade.
5. devenv sync
6. follow the migration procedure.
  
Actual results:
All migration calls fail at the mcollective client call.

Expected results:
Most or all migrations succeed.

Comment 1 Rob Millner 2012-03-29 23:27:25 UTC

This stems from running migrate-mongo twice on the same node.

Comment 2 Rob Millner 2012-03-29 23:42:03 UTC

Fixed in ae22944179.

Comment 3 Meng Bo 2012-03-30 05:28:11 UTC

check this case with latest migration scripts.
after running migrate-mongo-2.0.8 twice, did not get any error when running migrate-2.0.8
mark this as VERIFIED
