CentOS - Jul 2012 - EXT3-fs (dm-1): error: can't find ext3 filesystem on dev dm-1

Hello there,

I'm a new to linux need help in regards to issues during mounting of a new
created logical unit which I am unable to mount the volume due to error as
found below:

~]# mount -l -t ext3 /dev/mapper/vgNebula-lvg1 /mnt/iscsi0
mount: wrong fs type, bad option, bad superblock on
/dev/mapper/vgNebula-lvg1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

[root at HE ~]# mount -t ext3 /dev/mapper/vgNebula-lvg1 /mnt/iscsi0
mount: wrong fs type, bad option, bad superblock on
/dev/mapper/vgNebula-lvg1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

[root at HE ~]# tail /var/log/messages
Jul 24 16:31:37 HE kernel: EXT3-fs (dm-1): error: can't find ext3
filesystem on dev dm-1.
Jul 24 16:31:43 HE kernel: EXT3-fs (dm-1): error: can't find ext3
filesystem on dev dm-1.

Any help is very much appreciated.

Thank you.
