Patch [1] enabled etcd3 by default in devstack. Patch [2] adds the ability to disable etcd3 - this gets s390x devstack working again when the following line is in local.conf
disable_service etcd3
But this is just a circumvention. The root cause is NOT that etcd3 is not working on s390x (it is working!! [5]), but that devstack downloads the (architecture dependent) binaries directly from github.com, e.g. [3]. But etcd does not provide binaries for s390x on github.
Devstack does so, as most distros do not yet have the etcd3.x version available (e.g. with ubutnu 16 it's 2.x).
I opened an issue against etcd to figure out what would need to be done to get that going [4].
Alternatively the following approaches are thinkable:
- Enhance devstack to download the binary and compile it
- Enhance devstack to check whether etcd3 is already installed and use it - otherwise fail for s390x
