4 HDD's merge to one?

Hi,

I'm new to OMV, just installed 1.0. I have 3x 2TB disks and one 750gb disk. I've read as much as I can before starting this project. Is it possible to merge the disk to 1 big storage, pool them together? So I don't have to worry about a folder being full on one disk, instead it uses the empty disk when one is full without me noticing.

I've read about Greyhole, but from what I understand it is for backup, and not great when moving and changing files a lot. Most of my diskspace is Media which is replacable, but I have maybe 300gb important stuff that I want to backup automatically. Is it possible to chose one folder, or one partition of the disk that should be backupped to another disk automatically?

Thank you!

You probably want the aufs plugin.

Great, will read into that!

Not only aufs but some additionla scripts too.

Do you have any additional script in mind?
Thank you!

Yes, an rsync script to backup the folder you want to secure twice.

Great, thank you.
Looking trough the plugins, I can only find rsnapshot, is it the same thing as rSync?

This guide show both aufs and snapraid: http://omv-extras.org/simple/i…d=guide-aufs-and-snapraid
I have no use for snapraid if I use rSync right? Or is it needed for aufs?

And one more thing, if I add more disks later on, can I add them to the same pool?
Also, how do aufs structure everything, will it separate everything on different disks or will it fill up one disk and then go on to the next?
