[linux-lvm] LVM snapshot sizes.

I have created an LVM logical volume of the size arount 60G and
formatted it with reiserfs. After that I put MySQL database onto this
partition and made it a replicating slave.
Using this configuration I took several LVM snapshots, 1G each.
It did not take long for these snapshots to overflow.
So here is the question:
Why would it take so fast to overflow an LVM snapshot?
In other words, what are the parameters, which affect snapshot fillups?
Is it possible, that journaling filesystem can contribute to the size of
changing data on the logical volume, and would LVM2 be more efficient?
