[CentOS] Is glusterfs ready?

Hey,

since RH took control of glusterfs, I've been looking to convert our old independent RAID storage servers to several non RAID glustered ones.

The thing is that I, here and there, heard a few frightening stories from some users (even with latest release).
Any one has experienced with it long enough to think one can blindly trust it or if it is almost there but not yet ready?

Thx,
JD
