''Important things you have to know about the “LZ” (Greyhole Landing Zone(LZ).'

When you are going to use Greyhole as a disk-pooling service, you have to keep a few important things in mind. Standard in the Fedora/Amahi install guide there is a small partition for “/” (root aka System) like 20GB, recommendation for this size is bigger, but depends on the file batch size that is common for you to copy or move at the same time to you HDA-Pool (greyhole)

All data you copy to your HDA will first “Land” into your LZ The Amahi install guide suggest a small (Greyhole Landing Zone20GB) witch is located on "/" root partition (root / System also called system partition, or simply /drive) as default setting. From there While this is enough for most Linux systems, on it will be spread out over Amahi with Greyhole, this partition is used as a ''landing zone'' for new files you "Pool" shown as the example:copy onto your shares.

[[Image:GreyHoleLandingZoneAll the data you copy to your HDA's shares will first ''land'' into your LZ, which is by default located in /var/hda/files/share_name.Those folders are used as a temporary location for new files, which will be moved into the pooled drives as soon as possible by the Greyhole service, which runs in background.png]]

Basically to avoid problems in Here's a schema presenting the future and keep it simple, there are two things data flow for new files added to configureyour HDA's shares:

#[[Image:GreyHoleLandingZone. Make your "/" (System Partition / Drive) as big as the largest chunk of data that you copy/move to your HDA at a regular base.#. Don’t include your “/” (Root /System Partition/ Drive) into you Greyhole Pool! =How does it Work =png]]

From there Greyhole looks where it has # Pick a big enough LZ partition that will allow you to go (disks with space) and how many copy's it should make of enough data. Choosing the biggest drives you have is usually best.# Move the data (preferences LZ from the HDA Dashboard) if your que is empty (watch Greyhole commands how to see) it immateriality starts root partition to copy the data out of location you picked. That way, if the LZ to its final destinationever gets filled, if not it will be at won't affect the back rest of the existing queyour system.

Meanwhile it is still receiving your data in the LZ and filling up the que with final destinations and number of copy's. This means that it does 2 things on one disk at once The Greyhole wiki documents [http: 1. writing data into the LZ, 2//code. moving data to it's final destination on the disks present in your pool witch contains enough spacegoogle. All of the locations are being stored in a SQL database witch Samba uses com/p/greyhole/wiki/MovingLandingZone how to locate relocate your data when u request itLZ].

Of course there are If you'd like to learn more options for configuring your about how Greyhole uses the LZ, more details about this you can find in or just how it works, the Greyhole wiki has [[Greyholehttp://code.google.com/p/greyhole/wiki/HowGreyholeWorks more detailed information]] page, but is recommend for experienced users.
