Here's the run down: We have a 2 disk RAID 0 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.
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 0 and I don't really trust a whole bunch of non-tested tried and true programs.
I decided to try out Ubuntu LiveCD and
dd. I understand how to use
dd when we get names like
The drives, when I do
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.
