Extending RAID

[Morten W. J.]

Hi all.

Having an amount of data on my computer that doesn't seem to stop growing my 
wasy of organizing things is about to hit the roof of my harddrive.
Therefore I plan to use the "md" thingy to RAID two harddrives into a larger 
storage facility. Backup is handled by another mechanism so I don't need 
mirroringg - just more space.

My question is: When my ever growing data now have filled up both the RAID'ed 
harddrives, can I then without problems add a third, fourth etc. harddrive to 
my RAID partition without having to store my data another place during the 
extending of the RAID parititon. 

E.g.: If I have two X GB harddrives that are seen as a 2X GB RAID partition 
100% filled with data. Can I then stop the RAID services, add a third 
harddrive of X GB to the pool, restart the RAID service and then have a 3X GB 
partition 66% filled with data?

I hope my question makes sense....

Best,
