Hard Disk Size

[PKKR]

Hi,

If we want to increase Hard disk size for a VM. How do we do that? Can we do it while it is power on?

I have got the info from one website that:

While converting V2V, in the process customized settings, we can increase the Hard disk size.

I am not sure if the above is correct? If the above is correct, is there any alternate way.

Thanks,

Prashant

The question I posted is for ESX 4.0 and 4.1.

Thanks,

Yes its possible to extend the disk on vSphere Client and extend on OS level.

Which OS are you running and which drive you want to extend?

By using VMware Converter it is possible to extend the disk/voulme by selecting the advanced option in the disk screen

Does it only support for specific OS's? Can we increase both C & D drive?

Thanks,

Prashant

Linux and Windows HDD can be extend but like Troy Clavell said becareful with OS with active snapshot.

I would use gparted ( http://gparted.sourceforge.net/ ) to grow the size of the partition ( after you have resized the virtual disk).

Yes you can increase both the drives, What is the OS and do have seperate HDD fro both C and D

Hi,

If you have ESX 3.5 or newer:

1. Open VMware Infrastructure (VI) Client and connect to VirtualCenter or the ESX host.
   
   
2. Right-click the virtual machine.
   
   
3. Click Edit Settings.
   
   
4. Select Virtual Disk.
   
   
5. Increase the size of the disk.
   
   Note: If this option is greyed out then the disk may be running on snapshots or the disk may be at the maximum allowed size depending on the block size of the datastore
   
   
   
6. Follow the steps in Increasing the size of a disk partition (1004071) so the guest operating system is aware of the change in disk sizeR

yes.  NEVER increase the size of a HDD while the guest has an active snapshot.  The vSphere Client option will be greyed out, so that will help a bit.

While converting V2V, in the process customized settings, we can increase the Hard disk size.

yes, you can do it via converter, but it's quicker to do it post conversion.

You can use THIS LINK to see step by step how to do that in windows and linux.
