Dear all,
I am writing to seek your assistance in resolving an issue with my Ceph cluster.
Currently, the cluster is experiencing a problem where the number of Placement Groups (PGs) that need to undergo deepscrub and regular scrub cannot be completed in a timely manner. I have noticed that these PGs appear to be concentrated on a single OSD. I am seeking your guidance on how to address this issue and would appreciate any insights or suggestions you may have.
Please find attached the Ceph health detail output for your reference.
