Hello! It is clear what happens after OSD goes OUT - PGs are backfilled to other OSDs and PGs whose primary copies were on lost OSD gets new primary OSDs. But when OSD returns back it looks like all that data, for which the OSD was holding primary copies, are read from that OSD and re-written to other OSDs (to secondary copies). Am I right? If so, what is the reason to re-read copies from returned OSD? Wouldn't it be cheaper to just track modified ones?
Thank you. -- Dmitry Glushenok Jet Infosystems
