+Yes, that helps a lot.
+
+I'm not sure why it makes a difference (considering my own setup here is
+at least partially similar to yours), but I'll definitely dig into it more.
+
+Can you describe the LVM setup? i.e. how the lvm sits on top of the
+physical disks etc? I really want to try and reproduce the issue so I
+can make a good upstream explanation of the problem with the patch.
