Unable to export ceph information for multiple stacks

[John Fulton]

Unable to export two stacks at once [1] after the fix for 1884246 landed though I can export one stack at a time [2]. We need to be able to export two at once however, because we need to generate one file.

@John,

It does not look related to 1884246 as you've mentioned in the bug report. Normal export does not support multiple stacks specified with ','. AFACS, it's only specific to export ceph[1]. To me it is broken after your recent patch[2].

@Bogdan, these are recent regressions and not applicable to train.

Sorry for the confusion. I agree it's related to the my recent patch [2]. That patch is the fix for 1922249, not 1884246 so my original report should have said "after the fix for 1922249 landed" (not 1884246). I agree also it only applies to the current main branch (not train).

I've posted a fix for this bug: https://review.opendev.org/c/openstack/python-tripleoclient/+/785272
