This Greyhole UI app is an Amahi plugin to provide a user interface (UI) to the drive pooling technology Greyhole. Greyhole uses Samba to create a storage pool of all your available hard drives (irrespective of their size or they're connected). It allows you to create redundant copies of the files you store, in order to prevent data loss when part of your hardware fails.
JBOD concatenation storage poolConfigure as many hard drives as you'd like to be included in your pool. Your storage pool size will be the sum of the free space in all the hard drives you include. Your hard drives can be internal, external (USB, e-Sata, Firewire...), or even mount of remote file systems, and you can include hard drives of any size in your pool.
Per-share redundancyFor each of your shares that use the space of your storage pool, indicate how many copies of each file you want to keep. Each of those copies will be stored in a different hard drive, in order to prevent data loss when one or more hard drives fail. For very important files, you can even specify you'd like to keep copies on all available hard drives.
Easily recoverable filesGreyhole file copies are regular files, visible on any machine, without any hardware or software required. If you take out one hard drive from your pool, and mount it anywhere else, you'll be able to see all the files that Greyhole stored on it. They will have the same filenames, and they'll be in the same directories you'd expect them to be.
What Greyhole isn't
- Enterprise-ready: Greyhole targets home users
- A backup system: may we suggest CrashPlan for PCs and Time Machine for Macs?
- A replacement for RAID 1: If one hard drive disappears from the pool, it might take some time for Greyhole to make those files re-appear on your shares. Do not use Greyhole on systems where it's critical for files to be available all the time
- A replacement for RAID 0: While Greyhole might help balance the random read load across your hard disks, I doubt you'll see big performance improvements using Greyhole. Use RAID 0 if you need speedy disk access, or RAID 0+1 if you need fault tolerance too
- Select available partitions for the storage pool
- Choose shares and number of file copies
- Current status of the Greyhole daemon
- One-click Greyhole file system check (fsck)
All this can be done from the dashboard. If you installed by hand, see the transition guide to this app.
