At some point (not very long after starting), all I/O hung and the machine became totally unresponsive. This is with 2.6.34-9-desktop on x86_64. I then rebooted into openSUSE 11.2 (yes, 11.2 -- 2.6.31.5) rescue mode. I completed the pvmove, and transitioned once again to another software raid (shuffling disks about is not fun). Again it hung. *all* I/O hung, it appeared. This time, I managed to capture all of "dmesg" as well as "echo t > /proc/sysrq-trigger" and "echo b > /proc/sysrq-trigger". I had to cold cycle the box. Eventually the pvmove worked fine. I will attach the dmesg output.
