how to extend disk size of C drive OS (WIndows 2008 Server R2)

[ashokcharan]

Dear All,

I want to know how to extend C drive partition size.

C Drive there in Disk0 virtual drive & D drive in DISK1

kindly suggest how to extend Disk0 Size without losing data.

Hi there,

Do you have a separate VMDK for your C drive?  If so you should be able to increase the size in the VM settings, then in the OS go to disk management and extend the C:\ volume, all on the fly and all without losing data!

Hope that helps.

Good luck

Can you post a screenshot of the settings for both disks so that we can see what you are looking at?

[brunofernandez1]

are both VMDKs on the same datastore?

[ashokcharan]

There is a snapshot on the VM. You need to consolidate that before you can extend the size of Disk 1.

Kindly Advice how to consolidate ?

I already had to respond this question today once

Re: removing snapshots

[cjscol]

Right click on the VM, Select Snapshot....Consolidate (or Snapshot...Snapshot Manager and then Delete All).

Sorry What Will do after Deleting a snapshot.

[cjscol]

All of the writes that have been made to the disk(s) since the snapshot was taken will be applied to the base VMDK file from the Delta files. You will no longer be able to roll back your VM to the point you took the snapshot.

While there is a snapshot on the VM you are unable to increase the size of the disk.
