Expand virtual disk size in Raid 1.

I am running a Dell Poweredge T320 with a PERC H310 Raid controller.  I started out with 2 500 Gig disks in a raid 1 array.  Recently I wanted to expand the size of the virtual disk.  I got 2 additional 1 T disks and used OpenServer Manager to install.  

After the install the disks are all spun up and operating and Virtual Disk 0 reports a capacity of 1.861 Gigabytes.  Still at Raid 1 since I did not move to Raid 5 during the reconfiguration.  The two new disks show 961 G capacity and 465 used.  OK.  I understand that under Raid 1.  

The problem is the server reports the total disk size as 465 G, not the 1.8 G that OpenServer manager reports.  

I thought I might go back and reconfigure to Raid 5 and that might automatically expand the size, but reconfiguration through OpenServer is not an option.(Throws an error.)

Any suggestions about how I can get to the available 1.8 gig?

Thanks.

Hi,

If the virtual disk is showing the right size but the OS isn’t you need to expand the partition. What OS is it? With Windows you can use disk management.

Windows Server 2012.  Thanks, I'll give that a try.

RE: Expand virtual disk size in Raid 1.

You can only reconfigure a RAID 1 to RAID 5 by adding a third (or more) disk.

You said the old disks were 500GB, replaced with 1TB drives, and that you should be seeing 1.8G (2TB). That can ONLY be the case if you reconfigured the RAID 1 to a RAID 0 (DON'T do this!).

What exactly do you have and what and where are you seeing it?

RE: Expand virtual disk size in Raid 1.

I did not replace the drives, I added two 1 T drives.  I now have 4 drives, 2 500M and 2 1T.  Looking in Openserver manager i see Virtual Disk 0 is noted at 1.8 T.  The 2 physical drives show capacity 4.6 and 2 show 9.6 (or close I am not where I can read the actual numbers) and all 4 show RAID capacity at 4.6.  So, there is unused capacity, but I expected that.  I wanted to get 500M disks, but was offered 1T. Took the offer.
