Default How To Set Up Software RAID1 On A Running LVM System - upgrading kernel

when I upgraded my system (kernel) with apt-get dist-upgrade, raid doesn't work (when i unplugged one of disks, system can't boot)

I repaired /boot/grub/menu.lst but still doesn't work

Any idea?!?

Which distribution do you use?

Please make sure that all required kernel modules are loaded:
Code:
modprobe linear
modprobe multipath
modprobe raid0
modprobe raid1
modprobe raid5
modprobe raid6
modprobe raid10

Does the system boot? Do you see any error messages (also in the logs)?

no, it can't be booted. It's stops at Loading, please wait...
in the syslog I can't find anything useful... Don't know what should be wrong...

RAID was installed as you write down on the page... It'd worked perfect with both disks, with first or second... until... upgraded it wiht dist-upgrade
at installation he want to replace menu.lst, but I declined to do this automatically. After that I manually repaired it.

Now it boot only if I have both workin disks
