RAID1 array is impeding computer from starting up

I have a server that is failing to restart and gives the following output when doing so:

md: md1: sync done.
md: syncing RAID array md4
md: minimum_guaranteed_reconstruction speed: 100 KB/sec/disc.
md: using maximum available idle IO bandwidth (but not more than 10000 KB/sec) fo
r reconstruction.
md: using 124k window, over a total of 5116544 blocks.
md: delaying resync of md2 until md4 has finished resync
 physical units
md: delaying resync of md2 until md4 has finished resync
 physical units

I have never deat with such a problem and it is my understanding that the machine is trying to rebuild the RAID array and is having a problem (creating a starting RAID arrays is the most I have done).  Please let me have detailed instructions as to how to proceed.  Thank you very much.

    seems like you have 2 or more md devices requiring a resync on the same physical device

    to avoid slowdown only 1 md device per physical device is rebuild at the same time
    other devices will be rebuild when first md device is done

    just wait and sooner (or later if you have big disks) all md devices are in sync again

    The computer finished doing what it was doing and it seemed to shut down or at least stopped making noise.  This was late at night as I was falling asleep.  This morning I went to check it and it seemed to be off, because it was extremely quiet, but the lights were on.  To make a long story short I rebooted the PC and after the md: sections were done I got the following:

    INIT: Entering runlevel: 3
    INIT: cannot execute "/usr/sbin/ttyload"
    INIT: no more processes left in this runlevel

    I feel as though there are a few important files that are not quite fixed, even missing and would like to know a recommended solution, hopefully not along the lines of re-installing although that is always the easy way out.  Any help is appreciated.

    Accepted Solution

    1) try rebooting
    2) try a fsck from rescue media
    3) boot knoppix or rescue media and check if partitions look ok

    can you scroll up and check if all partitions were sucessfully mounted?
