Problem with activating CI/CD for an old project - Path has already been taken

Hi Folks,

we're running Gitlab 10.8.4 and having issues with this "Path has already been taken" issue.

I read https://gitlab.com/gitlab-com/support-forum/issues/1126 and https://gitlab.com/gitlab-org/gitlab-ce/issues/13707 .

We trying to enable a CI/CD Pipeline for a project called "dashboard" in the namespace "test". This project already exists for a long time

But after I enabled it, we see that Path has already been taken message - nothing else.

How can i check the paths for CI/CD builds inside Gitlab? Is there a known database query? Or a maintenance rake task for the git gitlab-rake cli tool? Currently i can't get any information out of the log files...it seems to be not to be logged to the logfile?!

There is also another namespace called "foobar" with a project dashboard and CI/CD enabled?

Are the CI/CD paths without the group namespace created, so we can get duplicates? If yes, than we/you need to fix this, for example with an edit field to change this path name, or just create randomly sorted hex whatever codes/id/uid for project, so we/you don't get duplicates anymore

I need to find out why this is not possible. Because it's driving us crazy.

Thanks

Cheers Christian
