If you want online snapshots you should have applied the VFS patch
which tell the fs to checkpoint itself ready for the snapshot to be
taken.  If you are using a database you will have to instruct the
database to do this checkpointing yourself.

It might be worth you waiting a few days for the 2.0 release which
will have the 'invalidate busy buffer' problem fixed.
