Hi all, I also hit the bug #24866 in my test environment. According to the logs, the last_clean_epoch in the specified OSD/PG is 17703, but the interval starts with 17895. So the OSD fails to start. There are some other OSDs in the same status. 2019-10-14 18:22:51.908 7f0a275f1700 -1 osd.21 pg_epoch: 18432 pg[18.51( v 18388'4 lc 18386'3 (0'0,18388'4] local-lis/les=18430/18431 n=1 ec=295/295 lis/c 18430/17702 les/c/f 18431/17703/0 18428/18430/18421) [11,21]/[11,21,20] r=1 lpr=18431 pi=[17895,18430)/3 crt=18388'4 lcod 0'0 unknown m=1 mbc={}] 18.51 past_intervals [17895,18430) start interval does not contain the required bound [17703,18430) start The cause is pg 18.51 went clean in 17703 but 17895 is reported to the monitor. I am using the last stable version of Mimic (13.2.6). Any idea how to fix it? Is there any way to bypass this check or fix the reported epoch #? Thanks in advance.
