aggregate_hd is a file system based on FUSE. It aggregates several harddrives on one single mount pount. Thus you can use several old disks to create one bigger disk. aggregate_hd works at the filesystem level. It spreads files on the differents drives. In case of a disk crash, only data stored on that disk are lost. File spreading over the different disks is done using the available space and a random value. Directory are created on every disk. Compilation: ./configure make make install Usage: aggregate_hd /mnt -o dirs=/data01:/data02:/data03:/data04:/data05:/data06
