RAID is Redundant Array of Independent Disks. It is a technology in virtualization which allows several devices to be grouped together and used as if there is only one device. If I have two or more hard drives I can group them together in a RAID and my computer will treat it as one device. RAID's purpose is for data redundancy and performance. I use software RAID in Linux. The other kind is hardware RAID in which you depend on chipsets to manage the RAID.
I have a RAID5 array consisting of 1x1TB and 1x2TB. I bought a new 2TB hard drive and I want to add it to the RAID. To make matters complicated I only made a 1TB partition out of the 2TB hard drive when I created the original RAID. I want to use the entire 2TB capacity of the hard drive and then add the newly bought 2TB hard drive to the RAID.
I have been using the RAID array since April 2016, so there's data written on this array now.
old RAID array:
/dev/sdb1 - 935G (2TB) - raid5 - /dev/md0
/dev/sdc1 - 931G (1TB) - raid5 - /dev/md0
Can this be accomplished without data loss?
