    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 :mad:
    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 :(
