People may use Gluster for HPC; I don't know. But it really isn't suited. I run two Gluster clusters for more boring enterprisey reliability. It is still kind of a mess - there are rough edges all over. Log messages make zero sense by themselves - you either need to learn what they're indicative of or read the code. Frequently, typoing configuration commands (configuration is mostly imperative command line driven, not via configuration files) so that it fails, actually does make changes, such that you'll have to unwind what it did before you can try again, etc. All that said, Gluster is pretty solid for our sue - distributed, fault-tolerant POSIX storage. But I wouldn't use it in an HPC environment.
