6장. HCI 구성 확인

프로세스

2. NUMA 및 메모리 대상 구성을 확인합니다.

   [ceph: root@oc0-controller-0 /]# ceph config dump | grep numa
     osd                                             advanced  osd_numa_auto_affinity                 true
   [ceph: root@oc0-controller-0 /]# ceph config dump | grep autotune
     osd                                             advanced  osd_memory_target_autotune             true
   [ceph: root@oc0-controller-0 /]# ceph config get mgr mgr/cephadm/autotune_memory_target_ratio
   0.200000
