Good day I'm currently decommissioning a cluster that runs EC3+1 (rack failure domain - with 5 racks), however the cluster still has some production items on it since I'm in the process of moving it to our new EC8+2 cluster. Running Luminous 12.2.13 on Ubuntu 16 HWE, containerized with ceph-ansible 3.2. I currently get the following error after we lost 1 OSD (195). I'm forced to repair, scrub, deep scrub, restart OSDs etc, everything mentioned in the troubleshooting docs & information from IRC but cannot for the life of me get it to work. What I'm seeing is, that pg 9.3dd (volume_images) has a status of 1 OSD (osd is down) which I know, but the other OSD shows 316 (not queried). Also pg 9.3dd has 4x functioning UP's but still reference the missing OSD under acting.
