Linux 2 drives, single mount point

so i have a pc with 2x 500gb hard drives in it one is full and is /home and the other is brand spanking new, i would like to make it appear as 1 mount point. That i can think of there is 3 options
1. JBOD
2. LVM
3. Give up and make two different mount points
4. Open to suggestions
With sda being full i dont want to reformat, and im guessing that would make 1 and 2 impossible? note 2 x 500gb are only for data, /boot, / and swap are on a different drive (currently an older 40gb ata ( plan to put it on a cf card at some point))

 

I'd go for LVM.

Create a PV on the empty disk, add a VG over there spanning the entire drive. Copy everything over to the VG.

Then, extend the PV and VG to span the 2 drives. Done (make sure you use a FS that isn't picky about resizing )

 

How reliable is LVM? I was thinking about giving it ago for my server.

 

looks like i have some reading to do lol, how is ext3 when it comes to resizing? what i normally use as it was what people recommended at the time

 

Any non journalling FS won't have a problem at all, and most journalling filesystems will do fine too. Ext3 can be (online) resized if your kernel supports it with a tool (resizefs IIRC).

 

would the stock kernel of debian-net install downloaded today be likely to have it or will i need to look at finding/compiling a different one.

 

I think THIS will answer your questions

 

i think between that and the doc on tldp i should be good thanks, ill hopefully get to try this weekend. Do you know of other blogs with intersting nix stuff?
