mount drive problem

[Zion Ahead]

I had to reload a server for a client due to the primary drive being corrupt. Secondary drive is untouched and *should* have backups on it.

This is what I did to mount it without formatting it:

fdisk -l

mkdir /backup
mount /dev/sdb3 /backup

Disk /dev/sda: 160.0 GB, 160000000000 bytes
255 heads, 63 sectors/track, 19452 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14         144     1052257+  82  Linux swap / Solaris
/dev/sda3             145       19452   155091510   83  Linux

Disk /dev/sdb: 80.0 GB, 80000000000 bytes
255 heads, 63 sectors/track, 9726 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1          13      104391   83  Linux
/dev/sdb2              14         144     1052257+  82  Linux swap / Solaris
/dev/sdb3             145        9726    76967415   83  Linux

However, its ending up replicating (even in real-time) the primary drive, sda3 which is odd. How I know its replicating it is because Cpanel is currently being installed on the primary. Every few minutes I refresh the d -h output and both sizes on sda and sdb update to exact usage size. I even went into /backup and it looks like the primary which is odd.

Why would this happen?

mount /dev/sdb3 /backup
[root@server092 home]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3              72G  3.7G   64G   6% /
/dev/sda1              99M   11M   83M  12% /boot
tmpfs                 252M     0  252M   0% /dev/shm
/usr/tmpDSK           485M   13M  447M   3% /tmp
/dev/sdb3              72G  3.7G   64G   6% /backup
