Are there any opinions as to the best POSIXy distributed filesystem to use on top of DRBD? GFS and OCFS2 looks more or less identical. Both grow but don't shrink, both are pretty close to POSIX, both are in kernel and in reasonably active development. How am I supposed to choose?

Also, has anybody played with DST? Just merged in 2.6.30, seems pretty exciting.

I was jumping up and down when DST went in because it portends good things
for POHMELFS, which knocks the *socks* off NFS speedwise.

But now Evgeniy is making noises about moving POHMELFS to run atop the
elliptics distributed hashtable, and, well, if that means that it can't
export an ordinary filesystem anymore, it's useless to me, and to anyone
else who wanted the same ease-of-exporting that NFS was good at.

A shame.

(but perhaps I misread and it's just gaining the *ability* to use
elliptics as its backend, without losing the ability to use a regular
filesystem as well.)
