Not enough disk space on C: for Xchange

Hello All - Our mail server was poorly designed by having the C: drive
partition set to only 10GB (don't ask, I don't know either). We are
having all sorts of issues, but my main concern is our Exchange
database (granted is very small now < 4GB) which sits on the C:
partition. The E: drive (where data resides) is about 200GB or so. We
need to do two things:
1. Resize C: drive (know of any solid tools do so on a Windows 2003
SMB SP2 server?)
2. Move the Exchange database and files to E: to provide for future
growth
My approach would be to run (2) full backups, rebuild the partitions
from scratch (yes, reloading Windows) and starting new (very afraid!).
Your help and wisdom greatly appreciated in advance. Kind regards,

How much is free on C:\ and E:\? What is the physical disk configuration?

I would not rebuild the server. Take a backup, move the Exchange databases
to E:\, take another backup, then resize the C:\ partition.

Hi, Michael. Thanks for the info. I don't have experience in how to
make the C: partition bigger w/o rebuilding. The disks I believe are
(2) SCSI disks operating in RAID 1; (2) logical partitions (C: has
about 1.5GB of free space); E: has about 100GB of space. Thanks again,

You'd probably want to use something like Acronis Disk Director, if this
were something you actually needed to do.

You should be fine with 10GB on the system volume - just don't put any
*data* files on there.

See "How to move Exchange databases and logs in Exchange Server 2003"
http://support.microsoft.com/?kbid=821915&SD=tech

You could also uninstall any third party apps & reinstall them on D. Clean
out old $NTUninstall folders from %windir%.

Thanks again. I'll look into this and get back to the group with a
final outcome. I truly appreciate your input.

No problem. Good luck. Do run a backup first, just in case. It's rare that
something goes wrong during this procedure, but ....

Do a backup, then use the Exchange Management GUI to move the database (and
logs) to the E: drive.

Interesting. How do I deal with the C: drive?

Aside from 3rd party tools and a lot of risk, you won't be abke to resize
C:.  Given that, you want to move as many components as possible off of C:.
The databases, the transaction logs, the smtp virtual directory, redirect
the temp directory, the message tracking logs, etc.

This is all correct, and to the original poster, you can also move many,
many other things and I think you'll find 10GB is more than enough for
the OS partition. First and foremost, move your pagefile to another
drive. That will likely free up 1GB out of the box if it's not already
been done. You can also migrate your ServicePackFiles folder to another
drive (have to change one registry key) for several hundred more MB,
also kill any service pack uninstalls in the Windows folder. I have
supported many Exchange servers that had 8GB-10GB OS partitions, and
with just a little handiwork, end up with 1GB of constant free space on
the OS partition for temp files and software updates.

Thanks, Venger. Definitely key information you provided. I'll check on
the logs and SP files (have that registry key to change by any
chance?). Thanks again,

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup

ServicePackCache
ServicePackSource

Just change the path, and move the folder. Done it many times.

You may also have the i386 folder in the root of c:\ - that is almost
certainly the OS source files, those can also be moved to another drive.

The SourcePath key in the same registry location above controls where it
looks for the install files - if that key says C:\i386, then you can
move those files and change the path entry in the registry as well.

With all of this, you should almost assuredly be able to run with a 10GB
C: partition with tons of room (2GB probably), assuming you also moved
the Exchange logs and databases as discussed elsewhere in this thread.

Good luck,

Venger
