Friday random semi-serious question; Like many people I have too much data some work, some create some family, some other...etc. I have some on some backup USB drives that I have never gone back to and also a few unplugged HDD's in the tower (I can't remember even why). I don't really want to go and buy something (or pay for data of cloud storage) but I thought I might do something with the stuff I have lying around. Does anyone know if this is possible: - Set up a Raspberry Pi server which exposes a single file system - Link it to the USB HDD's of different sizes that I have lying around - I save my data to it for backups - The data is placed redundantly over the drives so it can recover from one [or more] dying Bonus point: - I can remove one of the drives and access the data on it directly (so it is FAT32 not Linux RAID) Any ideas? GFS? Cheers P
