I have configured everything using the option 1 : provider network Edit : Version I'm using is Antelope Instance IP a (looks like the machine is not getting an IP) Controller IP a Instances Network info Subnet submitted by /u/Zikalol [visit reddit] [comments ..read more

Has anyone attempted deploying multiple regions using Charmed OS? I have a maas controller in each region and juju controller with a separate model for each region (region1, regions2). It seems cross model relations is what I want, but can find very little information online as to how to use this to point the second region and the Keystone in region1. Of course region2 will rely on region1, but will looking DR solution for that later. submitted by /u/Foreign-Wrongdoer806 [visit reddit] [comments ..read more

My questions: I want to use my remaining two servers as Nova compute hosts. Can the other remaining OpenStack services be installed on vm's running in my VMware environment? Would this be acceptable production? What would be a better solution if not? Can I separate OpenStack services and install them on th ..read more

I'm using Openstack Yoga. I created an instance with 400GB of disk, but after 60 retries the volume allocation had failed (now I've changed block_device_allocate_retries to 500 in nova.conf). I later deleted the failing instance but the associated 400GB volume would not be deleted. I tried to manually wipe the volume using commands: cinder reset-state --reset-migration-status VOLUME_ID cinder reset-state --attach-status detached VOLUME_ID cinder delete VOLUME_ID but the volume remained in the "deleting_error" state, so I followed this other procedure to delete the volume directly from the ..read more
