Limited coverage of distributed storage/filesystems

[globalcitizen]

A comparison of the feature set and limitations of available open source distributed storage/filesystems wouldn't go astray. This would have to discuss the historical feature set and assumptions of single host based block devices/filesystems and the challenges of distributed access.

There are multiple classes of distributed storage, ranging from more open/namespacey stuff like URIs, magnet links and freenet, through to cluster filesystems with strong availability guarantees to DRBD-backed conventional filesystems (offering consistency guarantees plus availability).

Again, this would assist with linking theoretical knowledge to more pragmatic real world systems architecture / deployment concerns.
