Agreed. Everything that has a positive impact on performance and flexibility in configuring, and especially RECONFIGURING volumes would really make Glusterfs a star for flexible storage management.
A specific for instance is this: I was migrating from GlusterFS 3.04 to 3.1.1 running Distributed-Replicate. Additionally, going forward I wanted to split the storage pool into dedicated read-write and read-only namespaces. In order to do this, I split my storage pool of 6 servers in half, taking away the mirrored server of each pair. This left me with a single server to configure as read-write, and two servers to configure as read-only (since this was the most heavily used functionality here). Since I only had one server to setup as read-write, I had to set it up as Distributed, because Replicate required 2 bricks and I initially setup the read-write server with only one. Now that I had all of the new servers up and running, I was able to take down the old servers (after a service outage to update all of the client machines to the new Native glusterfs client). However, when I reconfigured the second read-write server, I had to have another production outage to delete the existing Replicate (only) volume and reconfigure it to be Distributed-Replicate. In addition, I had to restart the native Glusterfs client on all servers (all 175 of them) in order for them to be able to utilize the new configuration. I really do understand the making all of this work without a service interruption is probably hideously complex. That said, if GlusterFS COULD do all of this, it would really stand out in functionality over other distributed filesystems - even more so than it already does. I must add - though I have spent my fair share of time screaming at my monitor and cursing the day I ever got involved with software of this complexity - the truth is, that pretty much defines my relationship with computers in general :-). It has little to do specifically with GlusterFS, which I truly believe is Best In Class product. Please keep focused on what it does best (distribute large files for simultaneous access by multiple clients), and don't try to turn it into ZFS or some other general purpose file system. Thanks!
