the subject may already discussed, if this is the case, a reference would be much appreciated because I really searched and never found real answers to my questions.
I have a Ubuntu 12.04 LTS Server installation, I manage 50% with Webmin and the rest from the command line. I have a few hard drives in RAID 6. I would like to grow the cluster by adding 5 other hard drives without losing my data. Is this possible? And if so, is it possible to handle all via Webmin?
