I have a 1TB ext4 partition mounted at
/ with all my data and Ubuntu 11.04 (natty) installed.
Now this drive is almost full (I used it as a database server for some processing). RAID0 is ok, I can take a failure (touch wood). But I need a way to grow this partition.
I have a new 1TB drive I want to add, however as my Ubuntu boot and all data is on the one partition I'm not sure how I can go about setting up a RAID0 or LVM array without loosing all my data.
So the question is how can I extend my existing ext4 partition over two physical drives without losing data?
