OCFS2 crash

When trying to even cd or ls the mounted OCFS2 partition it crashes.  I think this is a combination of VMWare Server's problem and the way I mounted and symlinked to it.

More than anything this shows the problem and lack of forsight with VMWare, but also that OCFS2 is easily crashed if you do strange things.

Relevant OCFS2 Mount Points & Symlinks

/mnt/sda2/VMWare on /var/lib/vmware/Virtual Machines type none (rw,bind)

I think the space in "Virtual Machines" is half the problem and I was also experimenting on it with new symlinks and even deleting it at some points.  I think this is what did it since that "Virtual Machines" was remounted from the OCFS2 partition.
