I have a RH server with Raid-1 , I want to go to the single user mode , the GRUB of the kernel is "kernel/vmlinuz-2.4.21-4.EL ro root=/dev/md0" , I tried add "root=LABEL=/ single " to the end of GRUB but fail , I try that it is sucessful before installed the Raid-1 ( before installed the Raid-1 , no "root=/dev/md0" in GRUB ) , can suggest how to go to the single user mode now ? thx

One way of doing this is as follows.
modify you specific kernel line in the file /boot/grub/menu.lst
ex: << just that an examples from small system >>
FROM....
title Fedora Core (2.6.18-1.2849.fc6)
root (hd0,4)
kernel /vmlinuz-2.6.18-1.2849.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.18-1.2849.fc6.img
TO....
title Fedora Core (2.6.18-1.2849.fc6)
root (hd0,4)
kernel /vmlinuz-2.6.18-1.2849.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quiet 1
initrd /initrd-2.6.18-1.2849.fc6.img
--------------
In short just add a 1 at end of line
then reboot this should get you in single user mode ...
Do not forget to take out the 1 when you are finished so that at next reboot this does not boot once again in single user mode
enjoy life

Re: single user mode with Raid-1
Yes.
When you get the boot screen,
add single or 1 at the end.
If the root= parameter is correct, it send you in the single mode.
LABEL=/ means you aleady labeled / to some path
You may use e2label to label a disk
