[ceph-users] [CEPH] OSD Memory Usage

Hello, I am using a CEPH cluster. After monitoring it, I set: ceph config set osd osd_memory_target_autotune false ceph config set osd osd_memory_target 1G Then restart all OSD services then do test again, I just use fio commands from multi clients and I see that OSD memory consume is over 1GB. Would you like to help me understand this case? Ceph version: Quincy OSD: 3 nodes with 11 nvme each and 512GB ram per node. CPU: 2 socket xeon gold 6138 cpu with 56 cores per socket. Network: 25Gbps x 2 for public network and 25Gbps x 2 for storage network. MTU is 9000 Thank you very much. Nguyen Huu Khoi
