红帽全球峰会第 19 章 在 OSD 回填过程中启用更快的客户端 IO 或恢复 IO
在维护窗口期间，您可能希望使用客户端 IO 或恢复 IO。与客户端 IO 相比，恢复 IO 会显著减少 OSD 恢复时间。有效恢复配置集选项为 balanced、high_client_ops 和 high_recovery_ops。使用以下步骤设置恢复配置集。
先决条件
- 下载 OpenShift Data Foundation 命令行界面(CLI)工具。使用 Data Foundation CLI 工具，您可以有效地从终端管理数据基础环境并进行故障排除。您可以从客户门户网站找到兼容版本并下载 CLI 工具。https://access.redhat.com/downloads/content/547/ver=4/rhel---9/4.17.0/x86_64/product-software
