Description

Discovered while testing #1297. Looping pool creates eventually hang when the OSD rejects writes for being sent earlier than same_primary_since on the PG.
Turns out that the OSD was initializing same_primary_since based on the osdmap epoch when the PG was created locally, not when it was entered into the map.

A Fix is in testing now.

Well, I've found several different races and bugs. My current progress is in the wip-pg-creation branch, but there's still at least one issue creating...
Hopefully I can track it down tomorrow or on my way home.

Ah, I didn't have quite the right fix in for the PGMonitor's PG creation (I was only setting it properly for the localized PGs -- whoops!).

This issue is now resolved. However, there is a similar one that crops up when creating new PGs in a pre-existing pool. I've made bug #1358 to track that.
