Use lvm (one mount point) and extend the the logical volume as you need.I have Debian sarge, maybe I need to look into lvm, generally I dont trust soft-raids or lvms, unless they are mirrored over different channels or controllers. What happens if one of your lvm disks crashes ?Without soft-raid I guess the same as with your "single 1TB" disk. You have to restore from your backup media :-)) .
Thats what I thought, the lvm is no better then any old raid-0, hard- or software, where you just plonk one disk after another. If we are talking about terabytedisks, then that means hardware scsi-array-box or fibre-channel with bunch of satadisks or fibredisks and within the array you have hotswap spares. There are _only_ two ways of having 'single large disk', buy large enough disk, unfortunately today limit seems to be 300GB, if you want more get the array mentioned above. Of cource considering single disk failure, you are better off by buying the array in any case, like... http://www.promise.com/product/product_detail_eng.asp?productId=115&familyId=6
