我已经将
Linux(Fedora)服务器系统从IDE驱动器克隆到SATA驱动器,但是它无法启动,在交换机根目录时失败.我在目标驱动器上做了一个干净的安装,并通过检查initrd文件了解到在SATA驱动器上安装fedora时它包含了ahci模块,当我在安装工作期间没有SATA驱动器时没有使用系统.
所以我想运行mkinitrd来构建新的initrd,和旧的一样,但添加ahci模块(可能作为预加载)
我做了太多的猜测,所以我想在这里提出这个问题：
什么是从现有的initrd构建新initrd的最简单方法,只需添加一个模块？
这是两个init文件的差异
diff /media/disk/SATA_initrd/initrd/init /media/disk/PATA_initrd/initrd/init 50a51,52 > echo "Loading crc-t10dif module" > modprobe -q crc-t10dif 57,60d58 < echo "Loading ahci module" < modprobe -q ahci < echo Waiting for driver initialization. < stabilized --hash --interval 250 /proc/scsi/scsi 66a65,68 > echo "Loading pata_amd module" > modprobe -q pata_amd > echo Waiting for driver initialization. > stabilized --hash --interval 250 /proc/scsi/scsi
和我要修改的initrd的init文件.

解决方法
您无需担心所有已安装的模块.首先,启动进入救援盘.
chroot /mnt/sysimage # this is for Fedora specifically - YMMV
cp /boot/initrd-2.26.27.24-78.2.53-fc9.x86_64.img \
/boot/initrd-2.26.27.24-78.2.53-fc9.x86_64.old
mkinitrd --preload ahci -f /boot/initrd-2.26.27.24-78.2.53-fc9.x86_64.img \
2.26.27.24-78.2.53-fc9.x86_64
exit and reboot the system.
华而不实的
在“驱动程序初始化”之前,您不必担心所有的modprobes
ignore --> use the --preload *MODNAME* in the arguments to mkinitrd ignore --> for all the rest use --with
只需添加–preload ahci
