Yes and no. You can combine two disks to get a bigger disk (RAID 0 striping) but as fas as I know you can't do it without destroying the data on the disks. RAID 0 also has a reputation for losing stuff - if one disk goes down, the combo goes down with it. >From what I remember about striping, the cylinders are alternated so that cylinder 20 (eg) on the combo might be composed of cylinder 20 from disk 1 and cylinder 20 from disk 2. Since the original files may have been written contiguously from (say) cylinder 20 head 1 then head 2 then head 3, I don't see how this can be translated on the fly into a read from disk 1 cyl 20 hd 1 then disk 2 cyl 20 hd 1 then disk 1 cyl 20 hd 2 etc (alternating disk selections). Now that's the theory (please feel free to correct me - this is just off the top of my head). In practice I have NEVER tried striping disks. The concept gives me the willies - just think, lose one platter and you lose the lot. A better proposal would be to plug the new drive in, configure it as a separate unit and stick a simlink in on the first filesystem that points to a directory on the second disk. If you really have to have it all in one directory, you might be better off getting a new, bigger disk.
