increase vmfs volume

[admin]

Is there a way to extended the partition of the vmfs volume that I created on my ESX 3.5 m/c?

During the ESX installation, there was a partition created on one of my storage drive volume and some free space left on it. From VI client, I got added the storage with space showing of the partition and now I have stored all my VMs under it. Right now, I am running out of space for that storage and need to use the free space on that disk. is there any possibilty of make use of that free space in any way?

It was by mistake I created the partition on the drive where I wanted the create the vmfs volume.

I tried changing CHS using fdisk but it displays as the Resource is busy

I dont have an option to add a new storage to the server

Changing the CHS isn't going to help you(unless you want to reformat).

Best idea is to copy data off to external, then rebuild partition to meet your needs. I don't know of any disk utilities such as PM that

will work with vmfs......

Hello,

The short answer is No, there is no way to change the size of an existing VMFS. The long answer is you can use extents (avoid this if you can) or make a bigger LUN and migrate the VMs to that LUN then trash the other LUN. Ideally you really want More LUNs and not less when dealing with SANs. Which is not necessarily the case when dealing with local storage.
