I don't think there's anything in /etc/zfs apart from the NFS exports file. 
The list of currently-mounted pools and their devices is stored in
/boot/zfs/zpool.cache , and I believe is only used during bootup.  vdev
information itself is stored in the zpool labels; you can view that with
"zdb -l /dev/nnn", where nnn is one of the devices your zpool is bulit on. 
More info than you probably want:
