Treat multiple drives as one


Hi,

Does anyone know of a way to treat multiple hard disks as one? What I mean is, if I have 2 40Gb hard drives in a machine, is it possible to treat them as 1 80Gb drive, meaning I can have say a 60Gb file (crazy yes, but this is just an example) without any complaints about disk space etc.

I'm guessing this would in the form of a kernel patch or module, if it exists, hence thats why I'm posting in the software forum.

Thanks.

Unfortunately there is no way I know of to treat two drives as one drive, as these are also recognized and detected by your computer's bios, etc.

yes during install you can configure a software raid. not sure you can do this with ATA, but i know you can with SCSI drives. even if you do not have a SCSI raid controller as long as you have a SCSI controller you can setup a software raid.

this is for RH at least, and you have to manualy configure your HDs not let the OS do it automaticaly for you.

I think what you are looking for is LVM (Logical Volume Manager).

LVM Summary

LVM HowTo

That will allow you to add multiple drives to one "Logical Volume", which can span more than one drive.

Hmm.. forgot all about that sucker.. hehe. I don't mess with LVM as I love having multiple partitions.

Cool, I'll take a look at the LVM. Might now be able to make some sensible use out of the many small hard drives I have around the room.

Cheers.
