Hi I found an unfound object problem in my test environment (hammer). I suspect the reason is the wrong update of up_thru. from osdmap, the up_thru become smaller than before at an epoch. some old PGTemp messages with smaller epoch are prepared and executed, and change the up_thru to smaller epoch. maybe_went_rw is wrong for that interval. I think prepare_pgtemp should not change up_thru if it is smaller than current, and duplicated PGTemp messages not be sent ? Is this a bug or something wrong for me?
