Abstract This document provides instructions for deleting the Argo CD instances added to the default namespace of the OpenShift GitOps Operator. It also discusses how to remove the OpenShift GitOps Operator Operator is a two-step process: 1. Delete the Argo CD instances that were added under the default namespace of the Red Hat OpenShift GitOps Operator. 2. Uninstall the Red Hat OpenShift GitOps Operator. instances created. 1.1. DELETING THE ARGO CD INSTANCES Delete the Argo CD instances added to the namespace of the GitOps Operator. Procedure 1. In the Terminal type the following command: NOTE You cannot

CurveFS kv方案设计 curve实现块设备时，元数据不是扁平化的设计，而是采用来有目录层级的 namespace 方式，namespace 已经实现了 fs 元数据管理的雏形，具备了基本的元数据管理功能。（当时为什么要设计为 namespace 的管理形式？留有租户这个概念），直接基于 namespace 开发： a. 功能 软/硬链接：目前是都不支持的。软链接可以通过标识文件类型解决；由于
