combine 2 disks into one

[stock99]

hi,

I have a 700G hard disk use to store data only. Now I just brought another 700G disk and I would like to bind the two to create larger hard disk. Is there anyway to do it without formating the first disk's data? I didn't have the first disk setup as LVM,as i didn't anticipate the large data size increase.

If so, can anyone give me the commandline option to do it? I only have access in ssh at the moment.

I did a similar thing by creating a mount point for it in the appropriate place - where do you want to add the storage?

If you need them glued together seamlessly, then you can use either LVM or RAID0 (striping). In both cases, you need to make a backup first.
