Hmm I'm not completely sure; I switched to using a separate runtime for each plugin. > On July 29, 2020, 3:27 p.m., Qian Zhang wrote: > > src/slave/csi_server.cpp > > Lines 194 (patched) > > <https://reviews.apache.org/r/72716/diff/2/?file=2236468#file2236468line194> > > > > I think we should set this based on the CSI services in the related > > `CSIPluginInfo` rather than hard code here, e.g. in future we may support > > both node and controller services for Portworx. > > > > Or maybe we should not have this parameter at all?

Yea we may want to remove the service information from the plugin info, I'm not sure. I'll leave it there for now and just initialize the volume manager with the correct services here. > On July 29, 2020, 3:27 p.m., Qian Zhang wrote: > > src/slave/csi_server.cpp > > Lines 233-235 (patched) > > <https://reviews.apache.org/r/72716/diff/2/?file=2236468#file2236468line233> > > > > I am just curious what would happen if any of the initialization logic > > fail, how will the failure be propogated back? I updated the server so that now `start()` returns a future associated with the initialization. > On July 29, 2020, 3:27 p.m., Qian Zhang wrote: > > src/slave/csi_server.cpp > > Lines 244-245 (patched) > > <https://reviews.apache.org/r/72716/diff/2/?file=2236468#file2236468line244> > > > > Do we have to use `started` and `initializationCallbacks`?

The reason it's more complicated here is because we may add more "initialization logic" after server construction if publish/unpublish calls are made before the server is started. So we need an approach which will allow us to add more function calls which are executed during startup. I explored another approach while coding but this is what I ended up settling on, but I'm happy to explore other options if we can think of something better. - Greg ----------------------------------------------------------- This is an automatically generated e-mail.
