I can only imagine the associated 30-day-long fsck.

Hmm, ok, well maybe not that long, but it would require an impressive
machine :-)  Let's see, it takes an average 5-10 min to do an fsck on a
dirty 2GB news filesystem (probably closer to 5), so for 1500 times that
amount of disk space, 7500 minutes..  125 hours.. 5 days.

Assuming fsck doesn't have to swap.
