6장. HCI 구성 확인

프로세스

1. ceph 쉘을 시작합니다.

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

3. 특정 OSD 구성을 확인합니다.

   [ceph: root@oc0-controller-0 /]# ceph config get osd.11 osd_memory_target
   4294967296
   [ceph: root@oc0-controller-0 /]# ceph config get osd.11 osd_memory_target_autotune
   true
   [ceph: root@oc0-controller-0 /]# ceph config get osd.11 osd_numa_auto_affinity
   true

4. 특정 OSD 백필 구성을 확인합니다.

   [ceph: root@oc0-controller-0 /]# ceph config get osd.11 osd_recovery_op_priority
   3
   [ceph: root@oc0-controller-0 /]# ceph config get osd.11 osd_max_backfills
   1
   [ceph: root@oc0-controller-0 /]# ceph config get osd.11 osd_recovery_max_active_hdd
   3
   [ceph: root@oc0-controller-0 /]# ceph config get osd.11 osd_recovery_max_active_ssd
   10

5. 컴퓨팅 노드에서 reserved_host_memory_mb 구성을 확인합니다.

   $ sudo podman exec -ti nova_compute /bin/bash
   bash-5.1$ grep reserved_host_memory_mb /etc/nova/nova.conf
