combining mounts into one big drive.

LVM is really cool in that it allows you to take multiple local devices and
manage them as one large one, or split them up with virtual "drives" being
spread across multiple physical devices.

Is there any way to do this with network drives? I'm looking to implement a
front-end server that has any number of machines behind it who host large
drives to the front-end server. The front-end server in turn combines these
"mounts" into one huge drive for others on the network to use.

Any such service that does this already?

Thanks!

You can use network block device to do this. http://nbd.sourceforge.net.
Both lvm and raid should be able to handle the block devices created
using this method.

Perfect! I'm now looking into enbd.

Thanks!
