[arch-general] Software RAID w/ 4 Drives Fails

[Robert Howard]

RAID5 is one of the levels that can be added to after creation. I think you
should boot from the install CD and read the mdadm man page. It contains all
the information you need to do what you want. That said, when you try to
build the 4-drive array, do you get any errors reported? You may need to set
the partition type to Linux MD RAID for the new drive if you intend to use
the mdadm hook to assemble the array.

Can you add a drive to an array after it has been built?

I know you can add a hot spare, or remove a drive and add another, but I did
not think you could increase N, where the size of the array is N-1 * size of
each drive. How is the raid going to know which is data and which is parity?

Of course I could be wrong.
