2 hard disks.. to look like 1 mount point

alexxxis · 11-03-2007, 03:01 AM

Hi all,

I have a server running on debian Sarge and i am running out of space.

I would like to add a second hard disk and somehow make it an extension of my first one..

so 2 hard disks 1 mount point.. without having to delete the files from my first hard disk

is it possible?

I wouldn't think so, in my experience linux is not very supportive of more than one hard disk, let alone mounted in one directry. I don't think you'll have any luck, but let me know if you do.

Sure, but you'd have to set up LVM (logical volume management). This takes any available diskspace on any disk and makes it into a single partition. Point is, setting it up requires quite some handy-work from the commandline.

thanks Dutch Master,

that is what i need..

question though.. can i use LVM on a preexisting file structure?
my files are already in place and i just want to give more space.

i know it would be possible if you pre-configured it, but i have not.

Dunno. Maybe in conjunction with a RAID array? Btw, I see you're still running Sarge? Upgrade to Etch, you can shoot two problems with the same bullet

will see.. maybe not yet.. when are they going to stop supporting sarge?

Read LVM HOWTO from tldp.org

IN my opinion First make LVM partition on new disk
Transfer all the data from old one to new one.
Then make the old one LVM enabled too.
