Not yet…
Without me having the time and the hardware to do a real world test this week I’ve been spending a lot of time reading up on my future setup. It would appear that since GlusterFS doesn’t (at this time but Raid6 is slotted for version 1.7) support parity blocks, a Raid5 style setup would not be feasable. The best you could hope for with as little hardware as I have is to run a Raid 0 or Raid 1 setup. With some advanced setup and multiple drives across 2 computers, a Raid01 setup would be possible, but I don’t have the means to try it out.
Once I get all the kinks out of my current, sloppy setup, I will post a howto describing both the installation, setup and pitfalls I’ve encountered along the way.
