I had two 80 GB disks in a raid1 set and wanted to replace them with new 300 GB disks. Replacing went fine and 'mdadm --grow --size max' seemed to work fine until I tried to run 'pvresize'. pvresize complained that md device was smaller than before and refused to resize and soon after that there was also complaints about access beyond end of device.
After restarting md array everything worked fine and I was able to resize physical volume successfully. mdadm --version if that matters: mdadm - v1.12.0 - 14 June 2005 Feb 16 19:40:23 galileo kernel: md: minimum _guaranteed_ reconstruction speed: 1000 KB/sec/disc.
