Resize Partitions on HP Proliant running Win2k3

Posted on 2007-10-16

We have an HP Proliant DL380 G5 with 8 x 146gb disks.  It's currently set up as follows

C: Mirrored
D: Raid 5

I'm running out of room on D: but theres 132 gb free on C: that could be used.

What's the best way to do this?  I've done a bit of reading and by the looks it can be a bit hit and miss as to if it will work.

    That's almost certainly a hardware RAID.  In which case, I don't know of ANY way you'll be able to give D: more space by taking it from C: - they are separate RAIDs.

    You could possibly relocate some data to C: (C: is WAY too large in my opinion - it should be 12-20 GB).  but what you'd probably be better off doing is replacing the 146 GB drives in the RAID 5 with 300 GB drives (replace one at a time and it should rebuild the RAID onto the larger drives.  Then you would use the RAID management software to expand the RAID container, and finally use DISKPART to extend the partition in Windows.

    And don't forget, you can always buy external drives (Direct Attach Storage/DAS).

    You might want to think this through more before you start mixing too much user data and system files.  It cna also cause some security nightmares.  Another option is if you have spare slots, another RAID set - either RAID 5 or mirrored.

    If you absolutely have to move things to C:, look for shares that contain only data.  If you note the security and permissions on the shares, then delete the share (not the directory, but only the share), then move the directories to C:, then recreate the shares with the right security and permissions, the users will never know the difference.  The only way this wouldn't work is if someone is mapping to D$ instead of the share (this is very unlikely).

    If you move program directories instead, you will cause problems with the registry finding them.  By moving only data directories, you avoid this pitfall.

    You can also move the page file if it is on D:, but this will hurt performance.

    cheers guys, it is hardware raid.   the server is a VMware test lab and i need to add another guest that won't fit in the remaining space on D:   if i could somehow reassign some C: to D: i'd be right but i guess not?

    C: is the system partition and D: contains only VMs.   theres nothing more on the server

    Short of rebuilding it from scratch with all disks in 1 array and then 2 logical disks for C: and D: you're out of luck as they say above unless you buy an extermal enclosure plus controller since there are no spare slots and no larger capacity disks. That'll set you back about $3000 for a P800 and a MSA50.
