07:31:42 frickler I'm seeing issues with the nova-metadata service on stein, does that ring a bell with someone? from the logs it always seems to start with an eventlet traceback, then some requests timeout. sometimes it recovers, sometimes thing break completely and need a restart of apache2 http://paste.openstack.org/show/sjn1zlp9BYRX4zNGckmg/
09:10:10 bauzas frickler: sorry for the late bump, but eventlet and stein are in my mind
09:11:57 opendevmeet Launchpad bug 1825584 in OpenStack Compute (nova) stein "eventlet monkey-patching breaks AMQP heartbeat on uWSGI" [Low,In progress] - Assigned to sean mooney (sean-k-mooney)
09:11:57 bauzas something like https://bugs.launchpad.net/nova/+bug/1825584
09:15:45 bauzas frickler: also, fwiw, we deprecated using eventlet for the API by Rocky
09:15:52 bauzas https://review.opendev.org/c/openstack/nova/+/549510
10:11:44 frickler bauzas: actually the service is running with wsgi in apache, the traceback is seen within /var/log/apache2/nova-metadata_error.log , I should have noted that
10:12:14 bauzas so a greenthread issue, I think
10:13:35 frickler ah, I just found https://review.opendev.org/c/openstack/nova/+/662095/5/releasenotes/notes/eventlet-monkey-patch-5f734ef581aa550e.yaml in the bug you linked, I need to check on those settings
10:15:07 frickler bauzas: ha, I think that's the issue, we have "threads=1" for nova-api, but =10 for metadata. hopefully that should be the issue already
10:15:20 frickler thx for the pointers
10:16:52 jkulik on that topic^ how does one deal with longrunning rpc-calls done from the API and the number of processes in uWSGI? It should block a whole process right? Thus making a DoS possible by doing a lot of volume-attachments in parallel (which does an RPC which holds a lock on the Instance)
10:18:47 lyarwood Only the initial part of the attachment is a call, the main part is a cast that should yield
10:19:02 lyarwood https://docs.openstack.org/nova/latest/reference/attach-volume.html
10:19:44 lyarwood I haven't had enough coffee to fully answer the impact of threads=1 on that flow however ;)
10:20:22 jkulik if there's an attachment running already, this takes the Instance lock. then all the other calls from nova-api to nova-compute for reserving the block-device-mapping entry (says for k8s workloads attaching > 10 volumes) will wait on the lock
10:21:16 jkulik so would it be recommended to run nova-api with a high number of threads to counter that?
10:21:24 lyarwood right that instance lock will block the remaining attachments
10:21:41 lyarwood that isn't going to help
10:21:59 lyarwood so you can run additional nova-api processes to avoid the lock on that side
10:22:10 lyarwood but nova-compute also takes an instance lock per attachment
10:22:20 lyarwood and another connect_volume lock within os-brick per compute node
10:22:42 jkulik yes, I'm not worried about nova-compute. I'm worried about some k8s projects starving out other users of nova-api
10:23:19 lyarwood I'm not sure if the instance lock actually blocks anything else from being accepted tbh
10:23:27 lyarwood but I get what you're saying
10:23:58 lyarwood we've not had any reports of n-api rejecting requests with k8s calling into it tbh but it could be possible
10:25:02 jkulik we're still on eventlet with a low number of process and trying to go to uWSGI, it looks like we have to run a huge number of processes to accommodate for that
10:25:14 jkulik or play around with threads=100 or something
10:26:39 lyarwood would you mind writing this up as a bug https://launchpad.net/nova/+bug ?
10:30:40 jkulik if you think that helps, sure. I just wanted to get input on how to run Nova tbh.
10:31:45 lyarwood It's mostly so others in NA can chime in later today with thoughts
10:32:46 jkulik ok. I'll write the problem statement down
