SBS2008 Extending Server C: drive

I have a HP DL360 G5 SBS2008 server. It is now running low on disk space on the C: drive. There are 2 partitions on this server. There were 3 disks using Raid 5. I have added a forth disk and extended the logical drive. What would you recommend to extend the C: partition to make use of the new unused space? Windows disk management or a 3rd party disk partitioner?

I have already moved everything of off the C: drive that I can, SharePoint, Exchange etc. So this looks like my only option.

I would use Windows disk management.  I've never had an issue resizing using this.

As for other files to relocate...have you looked at the IIS logs?  These can grow huge and take up a lot of space.

How to Change the Log File Directory in IIS7:

1.  Open IIS Manager from Administrative Tools and click on the Default Web Site.
2.  Double-click the Logging icon.
3.  Type in the path to the new log directory that you want to use, or click Browse and navigate to it.
4.  When you’ve entered or chosen the new log directory click Apply.
5.  The new directory will be created (if it doesn’t already exist) when the next log entries are written by the server.
Usually you can't do this purely with diskmanagement, as the space you need to expand to has to be right after C:\, and that is usually not the case. Normally you have partition D:\ right behind C:\, and freshly allocated space comes after D:\. So basically you'd have to move D:\ to the end of the virtual disk first, and that can't be done natively.

On the other hand all you need to do is take an extra backup (which should always be done prior to manipulations on servers anyway). Then delete partition D:\, extend C:\, and then restore D:\.

Also delete the contents of C:\Windows\SoftwareDistribution\Downloads, that should free up quite a large amount of space. Besides that, SBS 2008 as far as I know also includes WSUS, you may want to make sure that is also on another partition, or you can probably clean it up to reduce the size it uses.

Hi ScottCha,

Thanks for your reply. I have tried all the various guides to clear space on the C: drive over the last few years. But it gradually diminishes again with system updates.

I have read that "Extend Volume" is only available if there is contiguous unallocated space on the right side system partition. Otherwise the option is greyed out.

My raid is 75% of the way through parity initialisation after extending the Array. So as soon as it has finished I will see what the situation is with extending the C: partition with disk management.

I will let you know how it goes.

Hi rindi,

Sorry didn't see your message before my post. So it would mean deleting D; drive partition. Extend C: partition, then recreate D: and restore.

So looks like it may have to be done while the server is offline for a while.

I have read that some of the 3rd party partioners can be used even if there is no space after C: with no reboot. But have not had any experience using them on a server.

While have a check for the softwaredistribution downloads, thanks for the tip.
3rd party tools can do this, but it will usually take just as long, if not longer, and many of them have to either reboot and then you have to wait for things to finish, or they aren't windows programs, so you need to run them via boot media (which both would mean the server isn't accessible during that time), or if they can do the job fully within windows, the server versions are expensive. So unless you need those tools for the future too, they aren't necessary.
