We had Raid 1 setup with two 1tb drives. I have swapped out the drives and now it was on two 2tb drives, however, the raid array is still only 1 tb in size. Is there a way to increase the size of the array without having to pull the data off and create a new array and put the data back on? Thanks in advance!

I ended up having to back up all the data with windows server backup. Then destroyed the raid...rebuild it and it restored the data. Everything worked fine. I tried using qparted and extended the partition of each drive but that failed.

I'm pretty sure you're going to have to back up the data, destroy the RAID1, create a new RAID1, and restore the data.

The answer to this is highly dependent on the RAID controller you're using and the filesystem riding on top of the array, but the general/safe answer is "Back everything up, rebuild the array, lay down a new filesystem and restore". Even if you try to grow the array/filesystem "Back everything up" is still your first step. – voretaq7 Apr 11 '11 at 15:20
So would windows server backup be sufficient enough to back everything up and restore? Or is there a better way? – mahle Apr 11 '11 at 15:36
