commit a17851ab0ab1296e587c582523e9421a06e20597 Author: Roman Podoliaka <rpodoly...@mirantis.com> Date: Mon Mar 6 12:45:51 2017 +0200 nova-status: require placement >= 1.4 Since Ia1a0066dc30025c02553584a077365b28d8ff80e FilterScheduler will no longer fall back to not using placement API. We need to require version 1.4 to prevent NoValidHost errors. Closes-Bug: #1669433 Change-Id: I6666cb2f558ed1f4e83f21e0317a206b07c25134 ** Changed in: nova Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1669433 Title: nova-status needs to check that placement 1.4 is available for pike Status in OpenStack Compute (nova): Fix Released Bug description: In Ocata, nova-compute wouldn't start if placement wasn't available, but it didn't check the version so placement from newton will still work with ocata computes. Also, the filter scheduler will fallback to not using placement if the computes aren't all new enough yet, but even once the computes are upgraded if placement is not the latest and microversion 1.4 isn't available, then the filter scheduler will not find any resource providers and it will result in a NoValidHost error. For Pike, the fallback code for the older computes has been removed from the filter scheduler: https://review.openstack.org/#/c/436180/ So we're always calling placement from the filter scheduler. However, we don't enforce a minimum version of placement and we need 1.4 for the filter scheduler to work. We should add a check to the "nova- status upgrade check" command to enforce that placement is running with at least the 1.4 microversion (ocata) before upgrading to Pike.
