g-api unable to run

[Vincent Hou]

I am using the latest devstack and glance code. This is the error message when I run g-api using devstack.

Set rabbit_durable_queues = True in your glance-api.conf.

[Jiajun-xu (jiajun-xu)]

I also met the issue and setting "rabbit_durable_queues = True" could solve it.

[Nicolae Paladi (n-paladi)]

I have met the same issue;
when setting "rabbit_durable_queues = True" g-api can indeed be started;
However, Devstack always rewrites the glance-api.conf each time, resetting
"rabbit_durable_queues = False" so this breaks the execution of the devstack scripts

[Brian Waldon (bcwaldon)]

We aren't going to change anything in Glance to treat this. The only place that measurable work could be done is in Devstack (where we actually had a hacky fix for this at one point). I'll let the Devstack team triage this.
