[Rdo-list] [rdo-manager] - frustrating node

hi all i am attempting to build a 2 node basic overcloud. my previous emails have been talking about the problems i encountered. what i have : - 1 vm called rdo with undercloud AND overcloud. this one is has not been updated since november and i keep restoring snapshots to that date. - a 2nd vm called rdo2, full updated, overcloud fails to deploy to a specific physical node observations: (unscientific!) the 2 physical nodes are both good. i tested by redeploying on rdo again and again. i even swapped their order in instackenv.json and redeploying succesfully from instackenv.json step. however i have a particular machine that refuses to deploy. it doesnt matter what order. if it is the controller, it fails, if it is the compute it fails. i am using the same flavour on both rdo vms. but again, i believe i have ruled out that variable. how far did i reach? over the past few days i have opened the console and watched this particular machine pxe boot, get an ip, reboot, change its hostname to reflect the ip, reboot to localhost.localdomain (?) and the power off. i am not saying i sat down and watched it for the entire 209 minutes but i have observed it unscientifically last error: Deploying templates in the directory /usr/share/openstack-tripleo-heat-templates Stack failed with status: Resource CREATE failed: resources.Controller: ResourceInError: resources[0].resources.Controller: Went to status ERROR due to "Message: No valid host was found. There are not enough hosts available., Code: 500" Heat Stack create failed. real 209m19.252s user 0m21.695s sys 0m2.402s what am i looking for?: what do i look for in the logs? and my logs are huge; they dont get rotated for some reason i would like to know the reason this particular physical machine refuses to deploy, so i can fix it. i believe i have eliminated all variables except the machine itself and it has me puzzled and frustrated as i need to move on to the next stage of network isolation. any ideas? thanks -- <https://candidate.peoplecert.org/ReportsLink.aspx?argType=1&id=13D642... *805010942448935* <https://www.redhat.com/wapps/training/certification/verify.html?certNumbe... *GR750055912MA* <https://candidate.peoplecert.org/ReportsLink.aspx?argType=1&id=13D642... *Link to me on LinkedIn <http://www.linkedin.com/in/mohammedarafa>*
