Enlarge a partition under RAID

namchan · #1 Feb 22, 2005, 04:33 PM

Hello All Expert,

I would like to repartition in my fileserver. It is because that the main partition "C" drive is not enough space to install new program. My fileserver has "C" and "D" drive, "C" install windows 2000 server and "D" keep all data. Moreover the Fileserver running under RAID 1 (Mirror). When I install partition magic to the win2k, but it's not success. How to repartition or enlarge the "C" drive. Thank you for your reply.

Thanks and Regards
Nam

Please do not cross-post. Thanks.

Please elaborate on your situation, I'm not sure I understand. This is what I'm getting:

You have a windows "C" partition, which is too small
You have a windows "D" (RAID 1 array).

What is the RAID 1 array made up of? How many physical hard drives are in the machine, and what is the partition layout of each one?

Hello psi42,

Sorry, I don't know which forum I post it.

I have a fileserver with five SISC harddisk, run RAID 5.
C drive size is 4G for OS
D drive size is 100G for data

I want to enlarge C drive. How can I do? Which software can do this?
I try to install partition magic, but not success to install it.

Thanks and Regards
Nam

In your first post you specifically mention RAID 1. Now you are saying you have RAID 5 with SCSI. I assume you have 4 36GB drives in the array and 1 hot spare. Not that any of this matters. All that matters is how you can repartition the drive. Partition magic wass your best bet. Partition magic is breaking rules when it does its thing and thats why OS's don't do it natively. Have you tried Symantic Volume Manager? You are going to need a product intended for enterprises since raid-5 is not predominent for home use. It may be cheaper for you to buy or borrow a 100GB hard drive, back up the data, Reformat and reinstall the system, then restore the data.

Is this hardware or software RAID?

Appears to be hardware raid. At least Win2k Enterprise and Win2003 don't support hot spares in software raid.

hi, i have similiar problem.... just that i'm having two 33.6 GB scsi harddisk running on RAID 1, currently drive c have only 8 GB whereby the remaining space locates in drive d. Can really Symantic Volume Manager solve my problem, because my current OS is window server 2003 and have AD inside... i dun wanna backup whole thing and reinstall the system... troublesome and hard... If possible, i would like to do the resizing part only.

i know all the programs and data should be install into other drive... but the server wasn't handle by me previously. All i can do for now is to solve the spacing issue... if possible. So i wonder Symantic Volume Manager can do the resizing for me? And will it bring any impact to AD or other applications?

You currently have a mirror config (raid1) yes? Therefore I would break the mirror (this means you have 2 copies of the data

Then I would change the partition sizes of the first half of the mirror, and if that works re-create the mirror using the second drive!

This way you have a backup of the original setup should anything happen without actually having to make the backup
