Fwd: [opensuse-cloud] Since upgrade to Ocata cinder-volume causes high CPU load
Hi Eugen, 2017-10-18 9:38 GMT+02:00 Eugen Block <eblock@nde.ag>:
I compared the Ocata cinder code to Newton and Mitaka, an that function causing all this traffic to the cluster is indeed new since Ocata. So at least it's explainable, but how can I configure it properly? Any ideas?
If I understand your issue correctly, this is the fix you're looking for: https://review.openstack.org/#/c/508455/ it is already in pike or newer. Is there a particular reason you're staying with Ocata? We could backport it I think, as it is not changing any API, just wondering whether it is worth the effort (if someone wants it, it is..)

Hi Dirk, thanks for the link, that did the trick!
it is already in pike or newer. Is there a particular reason you're staying with Ocata?
We just did a triple upgrade to Leap 42.3, to Ceph Luminous and to OpenStack Ocata, all within a couple of days, I think we need a little break ;-) But if Pike is already stable we'll definitely upgrade soon to avoid another upgrade marathon across mutliple OS's and OpenStack releases ;-) Thanks again!

Hi list, during upgrade process from Mitaka to Ocata we were having troubles with two services: openstack-nova-api-metadata.service openstack-nova-api-os-compute.service They wouldn't start because of "address already in use" errors since metadata is served by neutron successfully, so we disabled these two services and didn't face any issue since. Now I stumbled upon this again because I wanted to write a little script, so I tried to figure out, if these services are still necessary in Ocata if you use neutron networking. I always check the OBS docs [1] for config changes etc.,and it still has this section for nova.conf: ---cut here--- [DEFAULT] # ... enabled_apis = osapi_compute,metadata ---cut here--- This has been enabled since Mitaka in our nova.conf. Since I have already faced some mismatches between the docs, I compared the compute chapters between OBS and Ubuntu docs [2], and indeed, in Ubuntu guide there are no "enabled_apis" mentioned for nova.conf (both control and compute nodes). So I'm assuming this should be applicable to OBS guide, right? So my question is, could I simply remove (or move) the service files /usr/lib/systemd/system/openstack-nova-api-metadata.service /usr/lib/systemd/system/openstack-nova-api-os-compute.service because they are not needed? Should I report a bug in Launchpad for this? Any insights are appreciated! Have a nice weekend! Best regards, Eugen [1] https://docs.openstack.org/ocata/install-guide-obs/nova-controller-install.h...
