Was: Plans for 1.8+ (2.0?) Now: Filesystem support?

[Peter Serwe]

There's a huge niche that desperately needs to be filled for systems 
that have huge
numbers of small files.  ReiserFS went some of the way towards doing 
that, but at
this point has pretty much officially flopped, and still has huge 
issues, not the least
of which are Hans' personal ones.  XFS and JFS don't have that as a 
sweet spot,
and have varying qualities of implementation under various *nix OS's, 
and ext3's
tuning/performance options once you fill a TB with the previously 
mentioned files
leave quite a bit to be desired.

I'm pretty much unfamiliar with ZFS, but for my own personal, selfish 
needs, I need
a filesystem that can handle double-digit TB capacities, store a 
bazillion ~4k files,
and deliver huge throughput to/from tons of TCP/IP clients. 

As an aside, a good replacement for NFS or architecting around NFS's 
weak points
would also be a plus.

    I am seriously considering our options with regards to ZFS or a
    ZFS-like filesystem.  We clearly need something to replace UFS,
    but I am a bit worried that porting ZFS would be as much work
    as simply designing a new filesystem from scratch.
    
One of the reasons people are so excited about ZFS is because it solves
the problem of managing space.  Disk management is and has always been a
pain in the rear, and ZFS goes a long way toward reducing that.
While constructing a new filesystem will help your goals, it will also
mean that DragonFly users miss out on having all the other advantages that
come with ZFS.  Put another way, we're going to lose planned
functionality.
