Red Hat Bugzilla – Bug 1282644
[Nova] increase reserved_host_memory_mb
Last modified: 2017-02-10 10:31:27 EST
Description of problem:
With zero swap being deployed with our overcloud (https://bugzilla.redhat.com/show_bug.cgi?id=1259539) we should really bump the reserved_host_memory to allocate a realistic amount of memory used.
Right now we default to 512MB. My idle compute node was consuming 1230MB. I would recommend setting this value to 2048MB on the compute nodes.
This bug did not make the OSP 8.0 release. It is being deferred to OSP 10.
This bugzilla has been removed from the release and needs to be reviewed and Triaged for another Target Release.
This was fixed incidentally here:
That change made it a param. Fixed was here: https://github.com/openstack/tripleo-heat-templates/commit/79e84f35b46e561d5f2d0a744d07c10285adecab
