Hi, I did setup CephFS forward scrub by executing cmd # ceph tell mds.cephfs:0 scrub start / recursive { "return_code": 0, "scrub_tag": "37a67f72-89a3-474e-8f8b-1e55cb979e14", "mode": "asynchronous" } But immediately after it started, memory usage on MDS that keeps rank 0 increased from 2GB to 32GB until MDS was killed by OOM killer. Why does it consume all the memory? Can it be adjusted somehow? Thank you
