[Gluster-users] striped replicated for VMs?

[Craig Yoshioka]

Quick question:

I’ve been using GlusterFS for about a year now to hold some VM images (KVM/QEMU).  My setup has been 2 replica servers, but I’m now interested in adding another two more servers to improve performance and space.  

The volume is currently configured as “distributed” (of just one replica set), should I (a) change it to striped for better VM performance, and (b) If I should change it, can a distributed volume be switched to stripe and rebalanced while live?  Or should I just add another brick directory to each of the servers and create a new (striped|distributed) replica volume?

Thanks!
