Additional setup and partitioning info
not an 'high' priority as not an issue with RHEV :-) This fails on native fuse mount due to non-support of ioctl on native mounts. ioctl(3, CDROM_DRIVE_STATUS, 0x7fffffff) = -1 ENOSYS (Function not implemented) Needs investigation whether bringing in support for ioctl on fuse-bridge is required. Removing rhs-2.0+ tag as ioctl support is not present with upstream fuse too. I have few info to add to this bug, 1. This happens only in fuse mounted , replicated volume 2. This happens only when trying to create qcow2 image with an option preallocation=metadata Targeting for Arches. The product version of Red Hat Storage on which this issue was reported has reached End Of Life (EOL) [1], hence this bug report is being closed. If the issue is still observed on a current version of Red Hat Storage, please file a new bug report on the current version.

Description of problem: Version-Release number of selected component (if applicable): glusterfs-3.3.0.5rhs-40.el6rhs.x86_64 libvirt-0.9.10-21.el6_3.7.x86_64 qemu-kvm-0.12.1.2-2.295.el6_3.10.x86_64 How reproducible: Always Steps to Reproduce: 1. Create qcow2 image with preallocation=metadata option[1] on a gluster mount[3] and try to fallocate it. Actual results: fallocation fails with operation not supported message and the disk size is just 1.8M. However, this works as expected on the host xfs filesystem[2]. And VM installation fails when this image is specified. Expected results: creating gcow2 image with preallocation=metadata option should be successful.
