   More specifically, it's the Solaris volume manager, isn't it?  I 
forget the specific incantation, but it is possible to tell Solaris 
"Forget about it" and treat a disk as a raw resource.

   It's probably a good thing for most users/workloads, but mostly Sun's 
volume manager just irritates me.
