Description Dmitry Tantsur 2015-02-17 13:55:43 UTC

Description of problem:
Discovery ramdisk detects _possible_ amount of RAM, not actual one. It was fixed in Git master by commit https://github.com/rdo-management/instack-undercloud/commit/9327553ecbbb7cc20bf32dd940bb32d02edb5b94 and in DIB ramdisk by patch https://review.openstack.org/#/c/156173/.

How reproducible:
on bare metal machines with RAM != maximum RAM

Steps to Reproduce:
1. go through discovery on such a machine
2. Node.extra[memory_mb] in Ironic will be updated with wrong value

Comment 3 Dmitry Tantsur 2015-02-20 14:23:38 UTC

Fixed in stable/juno branch of instack-undercloud as commit https://github.com/rdo-management/instack-undercloud/commit/02853ff37851736d0aecdda3d30afe94db35b782

Comment 6 Alexander Chuzhoy 2015-06-18 14:58:04 UTC

Verified:

Environment:
openstack-ironic-common-2015.1.0-4.el7ost.noarch
openstack-ironic-discoverd-1.1.0-3.el7ost.noarch
python-ironic-discoverd-1.1.0-3.el7ost.noarch
python-ironicclient-0.5.1-5.el7ost.noarch
openstack-ironic-conductor-2015.1.0-4.el7ost.noarch
openstack-ironic-api-2015.1.0-4.el7ost.noarch
instack-undercloud-2.1.2-1.el7ost.noarch


The machine has 48GB of ram.
After the discovery, running "ironic node-show <id>":
{u'memory_mb': u'49152'
