Windows Server 2008 RAID

Greetings,

I have two questions;

1) How do I determine what RAID (1,2,3,4,5) is being used. I know that it's NTFS.
2) What can I do with a C: drive that is low on space? The C: and D: volume are on DISK 0.

Thanks,

Brian

You would need to get into the BIOS unless its setup thru windows. There you need to look in Disk Manager

I'm looking at Disk Manager and do not see that it is RAID 5, It's looking more like just being striped.

Regarding the shortage of space on the C drive, is it possible to reallocate some off from the D volume?

Looks like F is just an external drive. If I remember it should say mirrored. There is no raid 2, 3 or 4. Raid O, 1, 5 etc. Restart and look at the bios. You might not even have the option to create one. The C drive is just cut into partitions.

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Okay, thanks. With that being said, could I extend the C drive if I delete the D drive (after backup of course, and then recreate D or is there a simpler way, even 3rd party software.

1) based on your disk management screenshot, it's hardware raid else you would see multiple dynamic disks in a software raid.  you shouldn't have to reboot if you install vendor tools (HP, Dell, etc.) that can manage the array

2) you'll have to use 3rd party tools to do this since shrinking a volume would make space available at the end of the volume (after D) but the free space needs to be contiguous which means a 3rd party tool needs to shrink from the front of volume D to allow C to be extended

How to shrink a partition?

Copy out the content of D: to your external drive. It is about 100GB data.
Then delete D: drive. Delete the Extended partition (the green frame around D: drive).
Then right click on C: and select - Extend. Add as much space as you want.
Then create again D: drive of the space left after C: drive.
Copy the data back. It is done. No additional software is needed. No RAID reconfiguring is needed.

And yes, it is a hardware RAID. Depending on the number of disks used in ARRAY it is either RAID0 or RAID5.

Thank you experts for your advise and recommendations. I will schedule time to give this a try and report back on the results.

What would you recommend setting the C: drive space allocation to?

Set it to 100GB. Must be ok for long time then.
