Spanning a hdd

Dark_Sniper* · 08-19-2005, 02:32 PM

This is for a freind

I've never had to do this before but my little test server has a two tiny hard drives in it.. One's starting to fill up so I'd like to span the hard drives to make one large volume.

Is there a way to do this without losing my data?

You will want to look into a raid 0 setup:

Yes, make sure you have a good backup.

Problem is the new hdd is alot bigger he told me so he thinks that the raid will fail. SO is there another way to transfer teh data to the new drive.

Ok well he jsut told me this .

I think you're not really understand what I want to do... Right now I have 2 hard drives... One is 10GB, the other is 15GB.

So right now it looks like this:

HD1 HD2
|------| |------|

I want to combine them to make one large linux partition

HD1&HD2

Look into the "Logical Volume Manager". http://ds9a.nl/lvm-howto/

If you don't want raid 0 or linear raid to do it then I'm not sure what will be the best, I've never tested it with lvm myself.

While a linear RAID array will do the trick, you should probably look into LVM. Linear RAID will simply create one large fs from 2 or more partitions. LVM does that (and more) but includes more tools for volume management.
