Disk Space, RAID Question


I have an HP ML350 G5, with a Smart Array E200i RAID Controller.

The system is running Windows 2003 R2 x64, and has two partitions.

The system partition is running low on disk space and I need to increase it.  The system has three drives currently installed.  My thought was to somehow add another drive to the system.

Has anyone done such a process?  I imagine it is a little more complex especially being the partition that is too small is the system partition.

Any help/insight!

You can expand your drive capability by creating a mount on the C:\ drive using space from your other drive.

You won't be able to just add another drive without re-striping the data across all drives. Unless your RAID controller supports it, that involves backing up the data, wiping the array, then restoring the data.

One thing you may try is an open source tool like gParted (http://gparted.org/) that will allow you to re-size the partitions so that you can "borrow" space from your other volume that has space to spare. I've never had it go wrong for me (and I've used it a LOT of times), but you should always back up your data before attempting anything having to do with filesystem reorganization.

If you're new to this type of process, it always helps to try this out in a lab environment first.

The issue is the system partition is only 30 gigs, and has roughly 1.5 gb free.  As updates and such role out it has shrunk and I'm running out of ideas to find more space.

I like the plug in new drive and use HP's utility to expand...  

Then use a partition utility to resize I'm just wondering if it has any issues with systems using RAID.  I've done that stuff and used gparted before.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

RAID, as long as it is hardware-assisted and not software, runs underneath your OS. So GParted and DiskPart etc won't care about it. Partition utilities work with the OS and logical drives at the OS level, ignoring RAID.

As always, backup your files before proceeding with any solution.

You can delete the softwaredistrubtion

net stop wuauserv
del /s /q C:\windows\softwaredistribution
net start wuaserv

This will buy you some space.

gParted recognizes most RAID cards (especially something main-stream as in a brand-name server) and should have no problems reorganizing the partitions.

30 GB for the System Partition of a 2003 server is a huge and a waste of space. Half of that would normally still be wasting space. If you follow Leew's instructions from the Link I posted you should be able to free up plenty of space.
