Changes

a) Connect to the VMware ESXi 5 server using the vShpere Client. Edit the VM's properties to increase the hard disk size (VM has  to be off) - I won't get into details on that, if you have the experience on managing ESXi you know what to do... I'm  assuming the process is the same for ESXi 4. Now restart the VM.

b) Login via SSH to the VM and follow this process.

- First list all partitions:

  $ ls -al /dev/sda*

- Create new partition using fdisk:

Then:

     type p - to list the new partition table

- Reboot server:

  $ reboot   

  $ reboot   

- Assuming you created partition /dev/sda3, let's now create the physical volume in that partition:   

* Assuming you created partition /dev/sda3, let's now create the physical volume in that partition:   

  $ pvcreate /dev/sda3   

  $ pvcreate /dev/sda3   

   

   

- Now let's extend the server's Volume Group to that physical volume.   

* Now let's extend the server's Volume Group to that physical volume.   

  $ vgdisplay   

  $ vgdisplay   

This will give you the info on your current Volume Group. Note down the entry next to "VG Name". That's your Volume Group name.

- Since we're (essentially) extending the main logical volume, let's get the name of that:   

* Since we're (essentially) extending the main logical volume, let's get the name of that:   

  $ lvdisplay   

  $ lvdisplay   

and note down the entry next to "LV Name". This is your logical volume's name (e.g. /dev/srv/root), which you'll now extend to  the newly added partition/physical volume.

- Extend the logical volume by X GBs:   

* Extend the logical volume by X GBs:   

  $ lvextend -L +XG yourLogicalVolumeName   

  $ lvextend -L +XG yourLogicalVolumeName   

Make sure you replace X above with the actual number of GBs you've added in your VM's settings. So if you increased your VM by  20GBs, the command becomes:

- Finally, let's resize the file system to the new allocated space:   

* Finally, let's resize the file system to the new allocated space:   

  $ resize2fs yourLogicalVolumeName   

  $ resize2fs yourLogicalVolumeName   

(this may take some time depending on number of GBs added to the file system.

- Check the new file system sizes:   

* Check the new file system sizes:   

  $ df -hT   

  $ df -hT   

You should now see an increased disk space for your primary logical volume.
