(setenforce 0) Can you share output of: ps -efZ | grep vm-name (filter the specific vm) ls -lhZ /rhev/data-center/mnt ls -lhZ /rhev/data-center/mnt/gluster-server:_path/sd_id/images/img_ id/vol_id (assuming the volume was not deleted after the operation). If the volume is not deleted after the failed move disk operation, this is likely a bug, please file a bug for this. The actual failure may be gluster configuration issue, or selinux related bug. Nir SELinux status: disabled
