Resizing VMs Using VMWARE Running 2003STD

Hello EE Gurus
  I have a question regarding the use of VMWare.  I have 2 virtual servers setup running some critical applications.  I'm using the VMWAre GSX server product and I've allocated roughly 50 Gig of space per Virtual Machine.  What I'm discovering is that neither of the 2 VMs really need that much space.  Is there a method to shrink the 2 current VMs to roughly half the size they use now? The 2 VMs are setup as single partition Basic disks running MS 2003 STD SP1.  The base server is on a pair of mirrored 146 Gig drives.  Any advice on the feasibility and process would be greatly appreciated.

Not sure as I don't have access to my GSX server at home (it's quite late here) but I think you may be stuffed anyway. Windows on a Basic disk won't allow you to resize down. Convert it dynamic will help but downsizing is always a problem. Generally speaking, you need to start again, and move your system (or restore it) back into the VM space.

Not tried it, but Partition Magic (or similar) should be able to help as if run from within the VM session, it would just see the session as an active partition. As I said, not tried it but the theory is sound.

Hope this helps

Attached is a VMWare support document discussing several disk operations that can be performed on a virtual disk. This is not a process I would attempt without doing a full backup of your server data.

Partition magic may be the simpler method of accomplish this. I have managed to boot PM on a VMWare workstation virtual machine. It appears to be able to handle the existing virtual drives properly. You just have to enter the VMWare BIOS setup by hitting "F2" during the POST and changing the boot order.

I was looking into this the other day as well but the problem is this: "Remember, you cannot shrink a virtual disk if you allocated all the disk space when you created the virtual disk."

I would be surprised if Partion "Magic" can handle VM partitions.  In most cases, you have to copy your data off to the primary partition, C:\ remove the partition, and remake a new one with VMWare.  That should not be too hard, as you will know where and what your system settings are for the VMware partition, if not use a date copy--

xcopy \\vm-partition\*.*  /r/s/h/c/k/e/d:01-04-2006 C:\backup\vmware1\newdata

You get the idea, you are copying all files changed since 1 April 2006 (or whatever date makes sense) to another drive, and then you remake the VMWare partition, and you copy the data back, and it will reboot is it was - magic!!
