    Rebooted 12.04 LTS server after updates, stuck at (initramfs) prompt now

    I just rebooted my server this morning and noticed that the server never came back online. I just got home, and turned the old monitor on, and it was sitting at the "(initramfs)" prompt. I just ran dmesg, and at the end it shows (paraphrased):

    Code:
    md/raid:md0: device sdc1 operational as raid disk 0
    md/raid:md0: device sdd1 operational as raid disk 2
    md/raid:md0: device sdb1 operational as raid disk 1
    md/raid:md0: allocated 4280kB
    md/raid:md0: raid level 5 active with 3 out of 4 devices, algorithm 2
    RAID conf printout:
     --- level: 5 rd:4 wd:3
     disk 0, o:1, dev:sdc1
     disk 1, o:1, dev:sdb1
     disk 2, o:1, dev:sdd1
    md0: detected capacity change from 0 to 3000606523392
     md0: unknown partition table
    md: linear personality registered for level -1
    md: multipath personality registered for level -4
    md: raid0 personality registered for level 0
    md: raid 1 personality registered for level 1
    md: raid10 personality registered for level 10
    Did one of my raid 5 drives die? What else could be causing issues? I boot from a separate 640gb sda drive, but /home is mounted on the md0 drive.


    edit: Scrolling up the dmesg output a bit shows:
    Code:
    md: bind<sde1>
    md: bind<sdb1>
    md: bind<sdd1>
    md: bind<sdc1>
    ...
    md: kicking non-fresh sde1 from array!
    md: unbind<sde1>

    Solved my issue... I had to re-add the "sde1" disk back to the raid 5 array, as it was marked as "non-fresh". It re-built the sde1 disk in about 3 hours, and then the system booted up fine afterwards.

    I ran this command to re-add the sde1 disk back to the array:
    Code:
    /sbin/mdadm /dev/md0 --add /dev/sda5
