I found a similar problem with 2 pools on one storage. If I remember right it was something like variable initialized for the first are used for the second or so... This was back some years ago and I forgot to summit a patch but happed again during our upgrade process. So I finally submitted the patch.
Maybe it is the same problem, I could test is next week.
