Okay, I've setup one of my nodes with a VG, and created an lvol on it.
I'm currently running a bunch of dd's (on the node in question) in 
parallel, and serially, in a loop, in an attempt to help speed up the
lockup getting triggered.

Oddly enough, the cluster has now been up for almost 4 days, and hasnt
locked up (typical!). I'm just hoping the non initnode dies first...
