Almost Re: Adding Disks to a 4400 (using existing RAID container)

On a somewhat similar but different tack... we've been looking at adding
more disks to an existing raid container and extending the existing ext3
filesystem that is there to include the new disks.  It seems that there
are reports that this is possible, but documentation is kind of thin. 
Has anyone successfull done this?  Or... are we just hosed and resign
ourselves to wiping the configuration and reloading when adding the
disks?

Thanks for any clues...
