RAID & Ubuntu Question

mBernhardt · 12-06-2006, 01:40 PM

I have a fileserver running Ubuntu 6.06 with a basic LAMP setup. (No GUI)

It's got 2 HD's forming a single RAID0 volume. (20GB + 30GB)

Does anyone know if its possible to expand the RAID0 volume (by adding an additional HD) without losing any of the data on it?

Sure, I could find storage space on my other computers for that data while I reinstalled the server. But, I'd much rather find a way to add an additional HD and expand the volume without needing to start from scratch.

And I do not just want to mount the additional volume under its own folder on the existing volume.

Note: LVM is NOT setup on the volume. In retrospect, this would be much easier if I had done that in the first place. But that ship has sailed.

Is this a hardware RAID or a software RAID?

If I were you, I'd back up and use the LVM.

Software RAID
