Re: Ceph storage system
#2Not sure if much has changed, but the last time I tried to install Ceph it wouldn't work under CentOS. That, and it was far too complicated to set up.
GlusterFS, on the other hand, was incredibly easy, although I am not a fan of FUSE due to the high CPU usage.

Ceph has a yum repo for Centos, although Cephfs still does not work (maybe it will be backported to the "ancient" EL6 kernel someday). You can use the fuse client instead.
Configuration-wise, Ceph involves quite a bit of voodoo compared to Glusterfs, it's an area where I hope to see some improvement.

One more feature I found very interesting in GlusterFS is the ability to export the volumes via NFS, transparently, to the NFS clients.

#5The guys behind Ceph are very smart, I'd keep an eye on this one as it's going to be awesome!

Is the metadata server still a single point of failure?

The metadata server has never been a single point of failure in Ceph.

Platform support (http://ceph.com/docs/master/install/os-recommendations/#plat...) and deployment tools have come a long way. In the past setup has been complicated (Ceph is inherently more complex than other systems), but it is getting much easier. There is also extensive documentation at http//ceph.com/docs, as well as very active IRC channel and mailing lists for support.
Ceph is much larger than just the file system (as the article points out). And while many Ceph products/subsystems are used extensively in production environments (RBD block store, RGW, and RADOS), CephFS isn't officially supported as production-ready.
Despite that, we run Hadoop on top of CephFS, and can deal with the occasional metadata server problem. CephFS is actively being hardened.
