It should work with ext2.
You can make reiserfs snapshots, but you also need to apply the
linux-2.4.0-test10-VFS-lock.patch that comes with the LVM 0.9 code. This
adds the hooks LVM needs to ask reiserfs to make the FS consistent before
creating the snapshot.
And, you need to edit linux/drivers/block/lvm.c, and uncomment the
LVM_VFS_ENHANCEMENT #define. This enables the LVM code that uses the hooks.
