[TriLUG] upgrading a software (md) RAID

[Charles Mangin]

i've currently got my home network server running a three drive RAID  
system. it's running md (software RAID) under Fedora 11.

the drives in there are 500 gigs, and with the prices of 1+ Tb drives  
coming down so low, i'd like to increase capacity. ideally, i'd like  
to do it without having to migrate my data to some intermediary device  
while i build a whole new RAID.

is there a good tutorial (that i've yet to find by googling) that has  
a good step-by-step on how to do this? the process, as i understand  
it, is to replace one drive at a time, rebuilding the array each time.  
once all the larger drives are in place, the final rebuild will show  
the new capacity. there's bound to be some mdadm fiddling necessary as  
well...
