    Here's the run down: We have a 2 disk RAID 1 array. One of the drives failed and the other is marked as depreciating. We aquired a new drive, same specs as the old. To our thinking we simply replaced the old drive with the new drive and theh RAID should have taken care of the mirroring all on its own. well, it did not. All it does is erase the new drive.

    Now we are trying to figure out a way to make the new disk a mirrored disk and I had a thought that if we simply copy the whole drive EXACTLY like the other one and put it back into the RAID card we should be good to go.

    Well, its not that simple, most copy programs don't do RAID 1 and I don't really trust a whole bunch of non-tested tried and true programs. Or does it matter? I should have just tried it anyways, we would have been no further from the start if it didn't work.

    I decided to try out Ubuntu LiveCD and dd... I understand how to dd when we get names like /dev/sda and /dev/sdb...

    The drives, when I sudo lshw -C disk show up as UNCLAIMED and they have no nifty little name that would have made this so much simpler.

    Any suggestions on getting this RAID array back up and running?

    We basically have one shot at this, as the other drive is the only copy of the server and it is marked as DEPRECIATING.

    I look forward to hearing from everyone.
