LVM uses a kernel patch to quiese a filesystem prior to making a
snapshot. (I don't think that will work for you.)
Do you quiese your data?
XFS in particular will not be happy with you doing the above. (ie. It
will zero out the data in any open files.)
Not sure how robust the other Linux filesystems are for this.
