第 9 章 卸载 Red Hat Openshift Container Storage
对于 Red Hat Openshift Container Storage，OpenShift Container Platform Advanced Installer 附带了一个 playbook 来卸载集群中的所有资源和工件。要使用它，请提供用于安装 Red Hat Openshift Container Storage 的目标实例的原始清单文件，并运行以下 playbook：
在卸载 Openshift Container Storage 之前，请确保所有使用 Openshift Container Storage 文件的应用程序，并删除了块物理卷(PV)并删除所有 PV。如果没有这么做，节点可能会继续保留资源，直到资源重启为止。
警告
此过程将破坏数据。请小心操作。
ansible-playbook -i <path_to_inventory_file> /usr/share/ansible/openshift-ansible/playbooks/openshift-glusterfs/uninstall.yml
ansible-playbook -i <path_to_inventory_file> /usr/share/ansible/openshift-ansible/playbooks/openshift-glusterfs/uninstall.yml
此外，该 playbook 支持使用名为 openshift_storage_glusterfs_wipe 的变量，该变量在启用后将销毁用于 Red Hat Gluster Storage 后端存储的块设备上的任何数据。有关将要销毁的设置/变量的更多信息，请参阅 附录 B, 使用卸载 playbook 时销毁的设置。建议您以以下格式使用此变量：
ansible-playbook -i <path_to_inventory_file> -e "openshift_storage_glusterfs_wipe=true" /usr/share/ansible/openshift-ansible/playbooks/openshift-glusterfs/uninstall.yml
ansible-playbook -i <path_to_inventory_file> -e "openshift_storage_glusterfs_wipe=true" /usr/share/ansible/openshift-ansible/playbooks/openshift-glusterfs/uninstall.yml注意
- 如果卸载 gluster-block，请确保删除与 /etc/target/saveconfig.json 中与 gluster-block 对应的条目。配置文件可能包含 gluster-block 以外的条目，因此需要手动删除 gluster-block 条目。
- 在 OCS 卸载后，从所有启动器注销所有危险的 iqn。
