The mount points are all on the same internal SATA drive.  They are always
mounted by /etc/fstab at boot, and I don't fool with them.  I did some
cable fiddling, and they are back.  As I type this, I'm running my backup
scripts.

If it happens again, I will try umount -f, but even if it works, I'll have
cause to worry.
