第 6 章 验证 HCI 配置

流程

1. 启动 ceph shell。

2. 确认 NUMA 和内存目标配置：

   [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. 确认特定的 OSD 配置：

   [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. 确认特定的 OSD 回填配置：

   [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. 确认 Compute 节点上的 reserved_host_memory_mb 配置。

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