Unable to mount a clone file system (NetApp)

Linux and Unix-Like Red Hat
1

Hi

I have the following difficulty:
the NetApp admin has clone one file system from one red hat server and presented this cloned LUN into another redhat server.
I can see the LUN as:

 fdisk -l

Disk /dev/sda: 64.4 GB, 64424509440 bytes
255 heads, 63 sectors/track, 7832 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I/O size (minimum/optimal): 4096 bytes / 65536 bytes
Disk identifier: 0x000d6bb9

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               2        1886     1047552   8e  Linux LVM
[root@simregebackup /]#

So I beleive is /dev/sdc because he told me the LUN has 1Gb

but when I try

 mount -t ext3 /dev/sdc /teste
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

Please can you assist, as I am not familiar with fdisk utility

How is the disk /dev/sdc used on the source side? It's labelled as Linux LVM so I'm guessing it is allocated to a volume group, which may then be one or more logical volumes formatted as filesystems or just raw space.

You target system needs to know what to do with it, but without destroying the content.

I don't have a test server I could play with like this, so I'm guessing a bit but somehow you need to build a volume group to include this disk without it rewriting the first few blocks else you would lose the LVMs it contains. Perhaps vgimport will help you here, but I've not used it before.

I hope that this helps,
