Hello BTW i am deploying via direct interface I ended up increasing the ram from 6GB --> 8GB and was able to provision. Looks like a min requirement may have changed. Re-opening bug as documentation states min requirements is 6GB not 8GB. please advise https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/15-beta/html/director_installation_and_usage/planning-your-overcloud#compute-node-requirements With the direct deploy interface you either use image streaming (I can elaborate) or the image needs to fit into RAM so that it can be converted. The minimum requirement of 6GB has nothing to do with that, it's calculated for iscsi deployment. We probably need to update DCN docs to mention this behavior OR use streaming. Removing blocker and setting as doc bug to document that when using direct deploy need to have enough ram to fit image (8 8GB in this case). Note that overcloud images are built requiring a minimum of 7 GB for tmpfs - https://github.com/openstack/tripleo-common/blob/master/image-yaml/overcloud-images.yaml#L37 Thank you bob i am closing for now. |
