  • Subject changed from cachepool: objecter: send requests to cache pool, then main pool on ENOENT to cachepool: objecter: send requests to cache pool, then follow redirect instructions
  • Assignee set to Greg Farnum

Our current thinking is that the cache/tiering flags specify the write behavior which the Objecter handles, and that if the OSDMap says so it directs all reads to the cache pool and follows whatever redirects that returns.

wip-6032-cache-objecter, currently based on top of https://github.com/ceph/ceph/pull/554
The objecter will follow the read_tier and write_tier redirects, and there is a workunit testing it.

Next up is defining the redirect interface and implementing it on both the OSD and Objecter sides.
