That was my intent...take out all of them, and leave two that have been
switched to 500gb drives.
Then grow them, then change things, then add the spare 500gb cloning the new
sizes.
Or just change them all to 500gb drives with the spare, having cloned the
raids, then grow the raid device.
So...that is the way to do it then? Sound good?
