Like Windows Home Server’s Drive Extender file technology, but want it on your Linux box? Greyhole is now available to all avid enthusiasts who would like to try it. It’s Windows Home Server Drive Extender concept, but open source, running on Linux. “Greyhole is an application that uses Samba to create a storage pool of all your available hard drives (whatever their size, however they’re connected), and allows you to create redundant copies of the files you store, in order to prevent data loss when part of your hardware fails.” So if you’re fed up with Windows 2003 Server overhead you’re now using just to get Drive Extender functionalities, or if you were waiting for an open source version to use it, or if you’d just like to help me… Start on the link below, and follow instructions in the INSTALL file, stated.
