红帽全球峰会21.2. 在 overcloud 节点上配置内核
Red Hat OpenStack Platform director 包括在 overcloud 节点上配置内核的参数。
- ExtraKernelModules
要载入的内核模块。模块名称列为带有空值的 hash 键：
ExtraKernelModules: <MODULE_NAME>: {}- ExtraKernelPackages
在从
ExtraKernelModules加载内核模块前要安装的内核相关软件包。软件包名称列为带有空值的 hash 键。ExtraKernelPackages: <PACKAGE_NAME>: {}- ExtraSysctlSettings
要应用的 sysctl 设置哈希。使用
value键设置每个参数的值。ExtraSysctlSettings: <KERNEL_PARAMETER>: value: <VALUE>
本例演示了环境文件中的这些参数语法：
parameter_defaults:
ExtraKernelModules:
iscsi_target_mod: {}
ExtraKernelPackages:
iscsi-initiator-utils: {}
ExtraSysctlSettings:
dev.scsi.logging_level:
value: 1
