Sage Weil 26cb966cab ceph-objectstore-tool: import pg at original epoch ... - In the jewel era, we fast-forwarded the PG to the OSD's latest epoch and cleared past_intervals. - In mimic, as of 2347ecb961, we brought the PG up to date while updating past_intervals. (At the same time we removed the OSD's parallel past_intervals regeneration.) The problem is that the tool then has to reimplement the past_intervals update logic, and *also* has to cope with splits and merges. Splits are somewhat easier (until now we enable partial import of a PG into a split child), but merges are not so easy. This patch changes it so we import the PG and leave the pg_epoch matching the import file. The OSD is then responsible for bringing it up to date with the latest map, and dealing with any intervening splits or merges. We also adjust the safety check to ensure that we don't collide with any existing PG, either a child we eventually split into, or a parent we eventually merge into.
