[Beowulf] Suggestions to what DFS to use

[Tony Brian Albers]

Hi guys,

So, we're running a small(as in a small number of nodes(10), not 
storage(170TB)) hadoop cluster here. Right now we're on IBM Spectrum 
Scale(GPFS) which works fine and has POSIX support. On top of GPFS we 
have a GPFS transparency connector so that HDFS uses GPFS.

Now, if I'd like to replace GPFS with something else, what should I use?
It needs to be a fault-tolerant DFS, with POSIX support(so that users 
can move data to and from it with standard tools).

I've looked at MooseFS which seems to be able to do the trick, but are 
there any others that might do?

TIA
