0k, i'll try it from here. UNAVAIL means ZFS can't locate correct vdev 
for this pool member. Even if this file exists it's not used by ZFS 
because it lacks ZFS headers/footers.

You can (I think so) reinsert empty file to the pool with:

# zpool replace storage /tmp/sparsefile1.img /tmp/sparsefile1.img

                 ^- pool ^- ZFS old vdev name ^- current file

If you replace both files you can theoretically bring pool to fully 
consistent state.

Also you can use md to convert files to devices:

# mdconfig -a -t vnode -f /tmp/sparsefile1.img
md0

And you can use md0 with your pool.
