Hi, Now that QEMU-GlusterFS integration via libgfapi is supported in GlusterFS-3.4 release, I documented a few failure scenarios to help the potential users of this feature. http://raobharata.wordpress.com/2013/08/21/troubleshooting-qemu-glusterfs/ Hope that users will find this useful when setting up and using QEMU-GlusterFS. Regards, Bharata.
