I echoed 2000000 (2M) in there, but nothing seems to have
changed. /proc/mdstat claims that it will be done some time
in the next 6 hours.  It is making progress, though -- it's
now saying "69.2% complete" vs around 65% last time
I checked.

Does it have to do this resync thing every time the machine
boots? That would be a really serious drag, and if that's
the case, I'll probably keep the two drives separate and
manually rsync critical stuff between them, instead of
using SW RAID.

Thanks for all the help so far, guys.
