How long should it take Disk Utility in Mac OS 10.4.8 to update a concatenated RAID when two new drives were added to it?

I have a Mac Mini running 10.4.8. I received two new LaCie 250GB drives for Christmas that I configured into a Concatentated Disk Set using disk utility. I then copied the approximately 400GB of data I had on two other drives to the new RAID set. This worked fine.
Once I was satified that everything was working off the new RAID disk, I added the two older 250GB drives to the concatentated disk set. I confirmed that Disk Utility could erase the two old drives in order to add them. I did this about noon today. It is 6:30pm here and Disk Utility still says "Updating RAID".
Creating the RAID was very fast. I expected the addition of the two additional drives to be reasonably quick as well. Not for any good reason, I guess. I've never set up a RAID before. I am suprised to find it still updating after 6+ hours.
So, hive mind, how long should I expect the update process to take? Should I just wait or is something broken?
