Package: qemu-utils Version: 1:2.1+dfsg-12+deb8u1 Severity: important Dear Maintainer,
I was testing writing a full disk image to disk with qemu-utils within a Docker container built from Debian Jessie with the qemu-utils package installed by running apt-get in the Dockerfile. The disk is configured as an Intel RSTe RAID 1 (imsm metadata) device built from /dev/sda and /dev/sdb with mdadm. The RAID volume exists at /dev/md126. The exact command I ran was this: qemu-img convert -t directsync -O host_device my_image /dev/md126 The image fails to write to disk with the following error: qemu-img: error writing zeroes at sector 0: Invalid argument I was expecting a successful write to disk. This succeeded previously when we based the container off of a version of Ubuntu which shipped qemu-img version 2.0.0. I found a similar bug in RHEL 7 that seems to have been fixed by upgrading qemu-img to the latest version: https://bugzilla.redhat.com/show_bug.cgi?id=1196688 The reporter of that bug suggested that a particular commit in qemu fixed the issue. The error does not occur when writing to a single disk (like /dev/sda) without RAID configured. I believe that upgrading qemu-utils so that the commit mentioned above is included will fix the issue.
