It was newfs indeed.   I had initially miscounted the size of the
second partition and instead of repartitioning, decided to put 0 in
the config file hoping that Vinum would choose the lowest common

Great, I'll do that.  Do you have enough information to fix the bug?
I presume the coredumps are of little use to you, because you already
