Adding New Disks

[Matthew White]

Hi,

I have a client with a Dell server running W2K3 SBE. He has no hardware
RAID, the RAID is setup through Windows Disk Management. He is out of space
and needs to add new disks. When I have this issue with a server that has a
RAID controller, I can easily add new disks, let the mirror rebuild, and then
extend the partition. However, here I don't have this option. Is there a
recommended way to add 2 new disks to the current Windows Mirrored set
without having to rebuild the box?

Any help is greatly appreciated.

Regards,

Matthew White

Software mirroring cannot be combined with any other RAID or advanced
volume type in software.

Mirroring doesn't allow for extending the current partition (short of
backup/rebuild/restore.)

With an ordinary volume (on a Dynamic Disk) you can extend into
a Volume set.

You can add the new disks for this, and you might gain some advantage
by moving large (non-System) directory trees to the new disk and using
"LinkD.exe" (Free from Microsoft Resource Kit tools online) to link
the current directory location to the new one.

Example:

Copy (e.g., Xcopy /s) all of C:\Program files to F:\Programs Files (or
even
F:\Programs)

Remove old copy of program files

Linkd the current location to the new one:

linkd "C:\Program files" to "F:\Programs Files"

This puts the contents of Program Files on new disk space without disturbing
existing programs.

You can also put the Cache file (or most of it ) there, Temp directories,
and
perhaps Profiles also.

You cannot do this type of thing for %SystemRoot% or most system directories
within it, especially not System32.

Is there any way to break the mirror, replace one disk, recreate the mirror, break the mirror again, replace the other disk, then recreate the mirror again. Then I would have new unallocated space.

Sure, you can break the Mirror and add another disk, but you will
likely have some trouble replacing the main disk with the OS -- this
is doable but it is tricky.

Perhaps a back and restore to the new disks is your best bet.

Re: Adding New Disks

This server has a lot of custom webserver configuration that I would prefer
to avoid having to do. Perhaps I will attempt the disk swap/mirroring, and
fall back on the backup, rebuild, restore plan. Do you have a link to a KB
for the best way to perform the full backup and restore?

Thanks again Herb

The built in help pretty much covers it.

You need a System State Backup or ASR (2003/XP+ only) to get a system
working again easily -- in additional to all the normal backup stuff.

Using third party backup tools can be easier if you have them.
