Crunch of hard drive space on your linux machine. Wanted to add new hard drive follow up the below steps (On Virtual Machine)

Step 1: Open VMware. Select “Edit virtual machine settings”




Step 2: Now click on Add… button.


Step 3: Select “Hard Disk” then “Next”.


Step 4: Independent option can be check  according to the need. Here I am keeping unchecked.



Step 5: Change hard disk size according to need.



Step 6: Start the Virtual machine.


Step 7: Open terminal and find out new raw partition name, as below (In my case it is /dev/sdb)


Step 8: use fdisk /dev/sdb to create new partition.




Step 9: We created the partition called /dev/sdb1.

Create one directory under root mount point.
#mkdir /d01
#mount –t ext3 /dev/sdb1 /d01

O/P Before mounting /d01 filesystem 




 O/P After mounting /d01 filesystem


NOTE: Be careful while editing /etc/fstab entries. It will cause boot problem (If in-case follow the link solution)  

To make it auto mount during the server boot add below entries to /etc/fstab file.
Eg. 

/dev/sdb1       /d01      ext3 defaults 1 2 


Command for unmounting the /d01 mount point


Command to mount: mount /dev/sdb1
