8.3. 删除 Block Storage (cinder)服务

流程

1. 在您要删除的节点上识别并禁用 cinder-volume 服务：

   (central) [stack@site-undercloud-0 ~]$ openstack volume service list --service cinder-volume
   | cinder-volume | dcn2-computehci2-1@tripleo_ceph | az-dcn2    | enabled | up    | 2022-03-23T17:41:43.000000 |
   (central) [stack@site-undercloud-0 ~]$ openstack volume service set --disable dcn2-computehci2-1@tripleo_ceph cinder-volume

2. 登录到堆栈中的不同 DistributedComputeHCI 节点：

   $ ssh tripleo-admin@dcn2-computehci2-0

3. 删除与您要删除的节点关联的 cinder-volume 服务：

   [root@dcn2-computehci2-0 ~]# podman exec -it cinder_volume cinder-manage service remove cinder-volume dcn2-computehci2-1@tripleo_ceph
   Service cinder-volume on host dcn2-computehci2-1@tripleo_ceph removed.

4. 在您要删除的节点上停止并禁用 tripleo_cinder_volume 服务：

   [root@dcn2-computehci2-1 ~]# systemctl stop tripleo_cinder_volume.service
   [root@dcn2-computehci2-1 ~]# systemctl disable tripleo_cinder_volume.service
   Removed /etc/systemd/system/multi-user.target.wants/tripleo_cinder_volume.service
