Thanks -- I have looked through the websites of some distributed filesystems
(Ceph, GlusterFS, MooseFS etc) and checked this thread too, but from what I
could find, all filesystems I read about so far are at most capable of RAID0 or
RAID1-like modes, where fault-tolerance is either not provided, or achieved
only by "all data is replicated across N nodes", which of course divides the
total usable space by N. I haven't found any FS which would do block-level
replication relying not on dumb copies, but on RAID5/6-like parity algorithms
for fault-tolerance. Maybe I missed something?
