That will most likely cause data corruption.
You need something like LVM snapshot (if using phy:/ with LVM-backed
storage) or use some storage-specific snapshot method (like vhd
snapshot, which is not available on Centos 5.5:
http://lxr.xensource.com/lxr/source/tools/blktap2/README). If you have
snapshot (using whatever method), then you should be able to safely
mount the snapshot on dom0, while domU continues to access the
original storage.
