/dev/TestMirrorGroup/OnlineVol is your root filesystem? I have the same
problem. Snapshots on other (non root fs) work for me. 

AFAIK snapshots and pvmove do not work on the filesystem where the lvm-tools
reside. I hope this will change in the (not so distant) future as I 
need snapshots on root-fs.
