Hi Brent

 

Regarding the raw cache review:

https://review.openstack.org/#/c/633400/

Currently the code is implemented according the discussion before between Ovidiu and Lisa: http://lists.starlingx.io/pipermail/starlingx-discuss/2019-January/002548.html

The raw cache is configured via “system storage-backend-modify”. e.g. system storage-backend-modify ceph-store cinder_raw_cache_gib=10

 

Your opinion is to decouple openstack from the storage backend. Thanks for your comment.

 

I take a look of system subcommand, there’s no subcommand for openstack currently, at this point “system storage-backend-modify” seems is the best choice. Should we add subcommand “openstack”?  Something like: system openstack cinder_raw_cache_gib=10

Or should we config openstack in other way? Could you please give suggestion on this? Thank you very much

 

Regards

Liang
