Title:
Existing Ironic instances report negative available RAM for the node
after upgrade
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Ironic nodes that have an existing instance will report negative
available RAM after upgrading beyond this commit:
https://github.com/openstack/nova/commit/b99fb0a51c658301188bbc729d1437a9c8b75d00
The node attached to the instance will not have
instance_info[memory_mb], etc, set on the node object in Ironic. This
code causes the driver to report memory_mb_used=memory_mb=0 if this
info is unset. The resource tracker notices that an instance is on
that node and sets memory_mb_used to X (the size of the instance).
After which the node reports (-X) available memory.
This can wreak havoc on tools that look at total available memory.
These could range from capacity reporting tools to scheduler/cells
filters. If more than half of the capacity has instances, the total
memory available will be negative, and could cause things to not
schedule properly or generate alerts.
