正如标题所说，我的系统上有多个内核
4.18.0-193.19.1.el8_2.x86_64
4.18.0-240.el8.x86_64
4.18.0-372.26.1.el8_6.x86_64
问题是我在系统上使用 mpt3sas，当我安装它时，它4.18.0-193.19.1是完美的。现在在较新的内核上，我发现内核没有检测到该模块。我无法对其进行 modinfo 或 modprobe。但当我尝试安装它时，它确实检测到它已经安装。如果这有区别的话，它在/lib/modules/4.18.0-193.19.1.el8_2.x86_64/weak-updates&目录中。/lib/modules/4.18.0-193.19.1.el8_2.x86_64/extra
有什么想法吗？我应该卸载它并在较新的内核上重新安装它吗？我尝试复制目录和 .ko 文件，但似乎没有什么不同。
编辑：我尝试删除其中的旧版本并通过 dnf 安装它，现在看来系统上安装了两个版本。以下是输出modinfo mpt3sas：

答案1
内核模块特定于内核版本，新内核也要求模块进行更新/重新编译。
当原始提供商尚未构建所需的新二进制 RPM 包时，安装源包并构建与新内核匹配的自己的二进制 RPM 包，即
例如https://www.ibm.com/docs/pt/ess-p8/5.1.0?topic=guide-instructions-updating-mpt3sas-driver
下载 SRPM
为正在运行的内核重建 RPM。
rpmbuild --rebuild SRC_RPM_LOCATION/mpt3sas-13.100.00.00-1.el7_2.src.rpm此命令创建两个 RPM。
卸载当前的 mpt3sas 驱动程序。
rmmod mpt3sas安装 RPM。
rpm -Uvh /root/rpmbuild/RPMS/ppc64le/kmod-mpt3sas*rpm rpm -Uvh /root/rpmbuild/RPMS/ppc64le/mpt3sas*rpm加载更新的模块。
modprobe mpt3sas验证模块是否已加载。
modinfo mpt3sas
