Description James Slagle 2018-10-03 13:01:15 UTC

We're getting several reports that 16GB ram is no longer sufficient for a minimum undercloud install.

Some examples are:

https://bugzilla.redhat.com/show_bug.cgi?id=1629062
https://bugzilla.redhat.com/show_bug.cgi?id=1634005
https://bugzilla.redhat.com/show_bug.cgi?id=1632461
https://bugzilla.redhat.com/show_bug.cgi?id=1634704

The default configurations of services should be checked since we switched to a whole new undercloud installation method in 14.

It would also be good to compare osp13 to osp14 doing the same sorts of deployments and stack updates.

If possible, we could also try installing an osp14 undercloud with instack-undercloud to compare resource usage.

If it turns out we need to increase minimum requirements for the undercloud, it will require a documentation update.

Hi James,

It looks like we bumped up the memory requirements for OSP14 to 24GB:

https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/14/html/director_installation_and_usage/planning-your-undercloud#determining-environment-scale

Was this enough?

Checked with Emilien. It should be enough. Feel free to reopen if it isn't.
