I know exactly what I would like to do, but I'm not RAID-Smart enough to know if this is an existing capability or completely impossible. Speaking in very generic terms, I have a RAID 5 array that is reaching it's capacity. Drives are cheap and I want to grow the array. Backing up the array to DLT is "hard" and I don't want to take my production system offline. I want to buy a stack of new (hot swappable) drives and do the following to my array: 1) pop out drive 1 2) Insert new drive 3) "initialize" the new drive 4) Some magic happens and the larger drive becomes part of the array lather, rinse, repeat for the remaining replacement drives and *poof* I have a larger array. This capability would save me an incredible amount of labor and hand wringing. Our "technology refresh" upgrades happen quite regularly because our data never stops growing. Is this a pipe dream or an eventual reality?
