Have Dell T310 server running Windows server 2008 R2. It has a RAID 10 configuration with four 465GB hard drives partitioned into C (for OS) and D for data. It is down to 15 GB free on D drive and also very little space on the C drive. I know I have to get 4 new drives. What is the most reliable, best, easiest way to transfer the configuration to the new drives without having to reinstall everything which would be a nightmare? And of course I then want to be able to increase the size of the D drive space so that all applications continue to see that drive as the place to write their data.
Can I create an image (have Symantec System Recovery installed), replace the new drives and restore the image? Can I replace one new drive at a time and and let it rebuild the array? Would there then be a way to expand the size of the D drive to the available space on the new drives?
I am thankful for any advice suggestions.
