Hi, I'm Yukihito, and interested in Linux system.
Thin provisioning iis a general design to save storage costs.
There's solutions in software and hardware in the market, including VMWare.
Higher range storage systems feature it.
And can write the files until reach to the physical maximum. Once reach to the physical maximum, I can't write any more files to that volume, but I can write more files after add additional physical disks to thin-pool.
Did you read Documentation/device-mapper/thin-provisioning.txt in the kernel source tree to use it yet?
It provides advice how to create thin-provisioned devices and snapshots (see dmsetup message examples).
There're no documentation written in Japanese, so I'll also output this communication to wiki or my twitter in Japanese. It helpful to make your work more major among Japanese IT engineers. And you can get more feedback if the challengers in Japan will be increased.
Keep in mind that there'll be LVM2 support available later in distributions.
You can pull that code from the HEAD of the LVM2 upstream repository for testing purposes already (not meant for production use obviously).
Thanks for trying it, we're interested in external feedback.
