Hi, I had a failure on 2 of 7 OSD nodes. This caused a server reboot and unfortunately the cluster network failed to come up. This resulted in many OSD down situation. I decided to stop all services (OSD, MGR, MON) and to start them sequentially. Now I have multiple OSD marked as down although the service is running. None of these down OSDS is connected to the 2 nodes with failure. In the OSD logs I can see multiple entries like this: 2019-12-09 11:13:10.378 7f9a372fb700 1 osd.374 pg_epoch: 493189 pg[11.1992( v 457986'92619 (303558'88266,457986'92619] local-lis/les=466724/466725 n=4107 ec=8346/8346 lis/c 466724/466724 les/c/f 466725/466725/176266 468956/493184/468423) [203,412] r=-1 lpr=493184 pi=[466724,493184)/1 crt=457986'92619 lcod 0'0 unknown NOTIFY mbc={}] state<Start>: transitioning to Stray I tried to restart the impacted OSD w/o success, means the relevant OSD is still marked as down. Is there a procedure to overcome this issue, means getting all OSD up?
