[SOLVED] Help with new disk but don't know how to add

Hi,

This Linux server is a VM, on the VMware, I added new disk for this system. I was not able to see the new disk. I did try the scan command but didn't work. I then rebooted the system. Now when I do


Code:
 
fdisk -l
Disk /dev/sda: 161.0 GB, 161061273600 bytes
255 heads, 63 sectors/track, 19581 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         268     2048287+  82  Linux swap / Solaris
/dev/sda3             269       19581   155131672+  83  Linux

On the Vmware, I added another disk for 150 Gig.

Here is the output from df -h


Code:
 
df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3             144G  135G  1.9G  99% /
/dev/sda1              99M   26M   68M  28% /boot
tmpfs                 942M     0  942M   0% /dev/shm

where is my new disk? how do I add that.

I was able to add the new...


Code:
 
fdisk -l
Disk /dev/sda: 161.0 GB, 161061273600 bytes
255 heads, 63 sectors/track, 19581 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         268     2048287+  82  Linux swap / Solaris
/dev/sda3             269       19581   155131672+  83  Linux
Disk /dev/sdb: 161.0 GB, 161061273600 bytes
255 heads, 63 sectors/track, 19581 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb4               1       19581   157284351    5  Extended

but when I do mkfs, I get error message. Any idea?


Code:
 
mkfs ext3 /dev/sdb4
mke2fs 1.39 (29-May-2006)
mkfs.ext2: invalid blocks count - /dev/sdb4
