I assume the steps would be the > following. What exactly do you mean by "now that I've upgraded them to 500GB drives". Don't tell my you got new 500GB drives, created little partitions on them to match the old drives, and added those to the array. That is the wrong way around. md is quite happy having using some partitions much larger than others. So if you have an array with (say) 4 200GB drives and want to replace them all with 500GB drives, you should make 500GB partitions on those drives (assuming that you really want to use partitions) and then one at a time, fail a working drive and add a new drive, and wait for recovery to complete. Once that is done you still have a working array of the same size as before but all the devices (and all the partitions) are larger. Then just mdadm --grow /dev/mdX --size=max and the array will resync the new space and be larger for you. Then you can resize the filesystem.
