I have a Dell T300 with a Perc 6i, to which 3 500Gb drives are connected. The are assembled into a raid 5 ~1000Gb VD. This setup is working fine, however system is filling up and I would like to increase capacity.
My idea was something along the following lines:
- Add a new 2Tb drive as a hot spare to the array
- Remove one of the 500Gb drives, so the 2Tb drive will replace it
- Once reconstruction is finished, repeat the process until there only are 2Tb drives in the array
- Expand the array size to fill the 2Tb drives, making the VD about 4Tb.
However, looking in the docs, I cannot find any information about point 4. So is the perc 6i able to expand a raid5 array? How?
Or should I proceed completely differently to achieve my goal?
