升级到内核版本:2.6.21.5
内核编译时成功,并且make install 后也自动更新了/root/grub/grub.conf文件,该文件内容如下:
#boot=/dev/hda
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux AS (2.6.21.5)
root (hd0,0)
kernel /vmlinuz-2.6.21.5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.21.5.img
title Red Hat Enterprise Linux AS (2.6.9-34.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-34.EL ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.9-34.EL.img
但是我以2.6.21.5内核启动时,出现错误,错误信息如下:
/proc/misc: No entry for devicemapper found
Is device-mapper driver missing from kernel?
Failure to communicate with kernel device-mapper driver.
0 logical volume(s) in volume group "VolGroup00" now active
mount: error 19 mounting ext3
mount: error 2 mounting none
switchroot: mount failed: 22
umount /initrd/dev failed: 2
kernel panic - not symcing: Attempted to kill init!

因为你的磁盘做了LVM,编译内核时记得选中 LVM support
