The disks are seen, the volume groups are seen.  When I try to activate the
VG I get this:

vgchange -ay vg1
  device-mapper: reload ioctl on  (253:19) failed: Input/output error
  0 logical volume(s) in volume group "vg1" now active

I executed 'vgchange -ay vg1 -vvvv -dddd' and this is the only time an
error was thrown.

I've uploaded two very verbose and debug ridden.

Ignore the naming.  It's not a gluster.  I was planning on making two and
mirroring them in a gluster.
