Does anyone have experience using gluster storage pools (backed by xfs filesystems) with KVM? I'm able to add a VirtIO disk without issue, however, when I try to create (or mount) an ext4 filesystem from the KVM guest, I get errors. If I use a gluster volume that is _not_ backed by xfs (e.g. ext4)) everything works as expected. I'm able to reproduce on CentOS6.4 x86_64 (2.6.32-358.6.1.el6.x86_64) with the following gluster versions: *) gluster 3.3.1 *) gluster 3.3.1-13 (built from EPEL SRPMs) *) gluster 3.4.0alpha3 I've poked around RH bugzilla, but haven't been able to find anything so far. For reference: "cache mode" on the VirtIO disks is set to "none" (to allow for safe live migration). Any ideas/suggestions? -Jacob
