I have a client whose C: drive is running out of space (and before anybody
suggests it, all data folders, Exchange data and clientapps folders have
already been reallocated). Fortunately, the drive is on a fairly large
hardware RAID-5 system with plenty of free space. Since the C: drive is
formatted as a dynamic disk, I know it's possible use Logical Disk Manager
to grab some free space and expand C: into it. I can even allocate extra
space immediately adjacent to the current C: drive.

My question is: is expanding a dynamic volume with LDM better or worse than
ghosting C:, deleting and recreating a larger volume and restoring the
image?

Hi Andrew,

I may be wrong but I thought you could not extend the system
partition/volume.

Regards,
Clive

Andrew, if you've moved everything off, I'd be curious as to why your C:
drive is still using up disk space. It should remain fairly static. What
about your pagefile? Have you moved that, too? The only other thought might
be that Volume Shadon Copy Services is taking up some of that space.

ghost doesn't work with dynamic disks. That isn't an option and just
wondered why dynamic disks were done in the first place....you HAVE to make
room somewhere since you are kinda screwed.

I agree, Mark -- I have yet to have an installation where I thought I might
gain something from using dynamic disk. As I see it, I had more to lose than
to gain ...

Correction - Ghost works with simple volumes on dynamic discs, not mirrored,
striped or other fancy volumes.

Kevin, the pagefile had already been moved.

I think the problem was that historically the server's original had been
upgraded all the way from SBS 4.5 days when it was originally on a 6Gb
drive. In its latest incarnation, it's a partition of a very, very much
larger RAID volume, but was originally created by mirroring the original
drive. I believe that 6Gb would be tight for most SBS installations,
particularly with 3rd party software added for Antivirus, AntiSpam, etc,
etc.

This volume expansion has been a while coming, but we knew of its necessity
from the very first day we upgraded to SBS 2K3.

Ghost does work with mirrored (dynamic) disks if you use the
partition-to-image method of creating the image:

The Ghost manual states you must break the mirror first (IIRC - I don't
have the manual in front of me this instant, but I'll check later &
correct if necessary).

It'll be interesting to see what you can find Steve. I can't find anything
in my Ghost 2003 manual about breaking the mirror prior to doing a
partition-to-image procedure with mirrored (dynamic) disks. I've seen this
question batted back and forth in the newsgroups before and it would be nice
to put it to bed.


Ghost compatibility with Windows 2000

are on Dynamic Disks, but not with other Dynamic partitions. Ghost can
create an image of a Mirrored partition that is on a Dynamic Disk, but can
only restore that partition to a Basic Disk (which breaks the mirror). See
the document Ghost compatibility with Dynamic Partitions. "

Okay, found the manual, and the reference to breaking mirrors.

If anyone ever wants an example of how to write a manual that contains
all the information, but makes it incredibly hard to actually
understand and follow, I want to hold the Ghost manual up at that
point...

Page 66 is the only one that mentions dynamic disks directly.

And it says "Ghost supports backing up, restoring and cloning simple or
mirrored volumes on dynamic disks. Spanned, striped and RAID5 volumes
are not supported by Ghost. You can back up an image of a partition on
a disk in a dynamic disk set to a image file. If you back up a disk,
then all of the partitions that Ghost supports on the disk, and only
those partitions, are backed up to an image file."

There's then a warning that only contiguous simple volumes can be
backed up.

It also adds further down the page "You can restore an image of a
dynamic disk only to a basic disk, not to a dynamic disk."

All clear so far, more or less.

It then talks about using the -ia switch to make a disk image of a
dynamic disk, but says it's only of use for restoring to the exact same
drive, and then on pg 67 says not to use -ia because it's very slow and
produces very large images.

Great.

Finally, the part that talks about breaking mirrors is in the
command-line switches section on page 159.

It's talking about Windows NT volumes rather than dynamic disks (a
point I didn't notice last time around - but then it was late, and the
manual was bedtime reading <g>), and how Ghost can create images from
Windows NT volumes, stripes and mirrors.

So, according to the manual, you *shouldn't* have to break dynamic disk
mirrors to image the partitions, but Ghost will only image the
partitions it understands, and they must be contiguous. And, assuming
you succeed in creating an image, you have to revert the dynamic disks
to basic in order to do a restore (which in a multi-partition scenario
is not very helpful, since a dynamic disk must be wiped clean in order
to go back to basic).

Then I guess I haven't seen an issue with using Ghost for imaging servers
because of how I use Ghost. I normally have servers with 1-2 drives, each
being mirrored to another set of drives using MS RAID1 software mirroring.
I take the server down, fire up Ghost from a set of Ghost Boot Floppies and
do the Partition-to-Image method for each mirrored drive using an External
USB drive to capture the image(s). If I need to restore the image(s), I
wipe the original disks clean (taking them back to basic disks), restore the
image from the USB drive, make the drives dynamic and then re-establish the
mirror.

Of course this wouldn't be very good for restoring just one partition on a
dynamic drive since the entire disk has to be returned to basic before the
partition can be restored. For that, I'd have to rely on the daily backups.

OK. I always direct A/V and Spam and all other utilities to install to a
drive other than the C: drive. So, if you have your quarantine email
directories on your C: drive, that could be your problem. If so, why not
uninstall your A/V and reinstall it onto another drive?

Again, what I'm saying is essentially that if all apps are installed on your
D: drive, then your C: drive should remain fairly static. I have several
sites with the default 8Gb C: partition as DELL created them for SBS2000,
and after doing inplace upgrades to 2003, they are sitting with about 3.5gb
of free space (or 4.5gb of used disk space).

Kevin, you're probably right in general about C: normally being static, but
it wasn't worth struggling over in this environment - we had tons of
capacity elsewhere on the RAID system, C: was already very tight on space,
so it was just a matter of finding the best method of increasing the C:
capacity.

Your comment about the Ghost manuals probably goes double for their web
site. The information is very badly organized.
