@admin_db, Snapshots are won't list in df -h. Instead list the Logical volumes
Code:
# sudo  lvs -o +devices

You have created your filesystem using
Code:
# mke2fs -t ext4 /dev/VGExaDb/data_snap

Then trying to mount with ext3 how it will mount ? Mount it using
Code:
# mount  /dev/VGExaDb/data_snap /snap_db

Hope this will mount.. Please provide us which operating system you using by running command
Code:
# lsb_release -a

If you need to know more about how to work with snapshot please feel free to read my article right here

pvck

PVCK(8) 						      System Manager's Manual							   PVCK(8)

NAME

       pvck - check physical volume metadata

SYNOPSIS

       pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       pvck checks physical volume LVM metadata for consistency.

OPTIONS

       See lvm for common options.

       --labelsector sector
	      By  default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0.  This parameter allows you to specify a
	      different starting sector for the scan and is useful for recovery situations.  For example, suppose the partition table is corrupted
	      or  lost	on  /dev/sda, but you suspect there was an LVM partition at approximately 100 MB.  This area of the disk may be scanned by
	      using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

	      pvck --labelsector 204800 /dev/sda

	      Note that a script can be used with --labelsector to automate the process of finding LVM labels.
