Rock9.1 dracut无法引导

Question

我的Logic9.1VM内核无法在引导期间加载/引导/解密LVM Luks2卷。用5.14.0-162.6启动很好。但是引导最新的5.14.0-162.18或5.14.0-162.12内核失败，dracut抛出错误：

Starting dracut pre-udev hook.
dracut-pre-udev[397] modprobe: ERROR: could not insert 'dm_mod': Operation not permitted.

/run/iniramfs/rdsosreport.txt

dmsetup ls --tree
/dev/mapper/control: open failed: No such device
Failure to communicate with kernel device-mapper driver.
Check that device-mapper is available in the kernel.
Incompatible libdevmapper 1.02.185 (2022-05-18) and kernel driver (unknown version).
Command failed.

我创建了一个新的initramfs。Grub设置和模块是相同的。

包裹都是最新的。我重新安装了内核、内核模块和lvm2，但没有成功。

通过执行/usr/lib/kernel/install.d/51-dracut-rescue.install.，我成功地通过一个活动CD色度重建了一个救援initramfs和vmlinuz救援系统正在启动5.14.0-162.18内核。但是很多模块都缺失了。

谢谢你的建议！

Answer 1

毕竟，在做了一些研究并从以前的内核版本中重新生成initramfs之后，这对我起了作用：

cd /boot
dracut -f initramfs-5.14.0-162.23.1.el9_1.x86_64.img 5.14.0-162.23.1.el9_1.x86_64
reboot

在5.14.0-162.23.1.el9_1.x86_64版本…上引导良好
