What obvious thing have I done, or not done, here?

What should I do now?

(I am not panicking, because I can always revert back...)

I tried to implement you suggestion,

# swapoff -a
# dd if=/dev/zero of=/swapfile1 bs=1K count=16M
16777216+0 records in
16777216+0 records out
17179869184 bytes (17 GB) copied, 119.642 s, 144 MB/s
# mkswap /swapfile1
Setting up swapspace version 1, size = 16777212 KiB
no label, UUID=9afbf206-9a79-45b8-ad4b-148f71c440d7

17GB is a bit ridiculous for swap, especially on a single user machine.

	I once encountered an fsck that required more than 400G.  I had to
kill the process, slot a new 500G drive, and enable swap on the new drive.
