Hello,
We get this error message while moving or copying some of the disks on our main cluster running 4.1.2 on centos7
This is shown in the engine: VDSM vbgkvm02 command HSMGetAllTasksStatusesVDS failed: low level Image copy failed
I can copy it inside the host. And i can use dd to copy. Haven't tried to run qemu-img manually yet.
This is from vdsm.log on the host: 2017-07-28 09:07:22,741+0200 ERROR (tasks/6) [root] Job u'c82d4c53- 3eb4-405e-a2d5-c4c77519360e' failed (jobs:217) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/jobs.py", line 154, in run self._run() File "/usr/share/vdsm/storage/sdm/api/copy_data.py", line 88, in _run self._operation.wait_for_completion() File "/usr/lib/python2.7/site-packages/vdsm/qemuimg.py", line 329, in wait_for_completion self.poll(timeout) File "/usr/lib/python2.7/site-packages/vdsm/qemuimg.py", line 324, in poll self.error) QImgError: cmd=['/usr/bin/taskset', '--cpu-list', '0-15', '/usr/bin/nice', '-n', '19', '/usr/bin/ionice', '-c', '3', '/usr/bin/qemu-img', 'convert', '-p', '-t', 'none', '-T', 'none', '-f', 'raw', u'/rhev/data-center/mnt/glusterSD/vbgsan02:_fs02/0924ff77- ef51- 43 5b-b90d-50bfbf2e8de7/images/750f4184-b852-4b00-94fc- 476f3f5b93c7/3fe43487-3302-4b34-865a-07c5c6aedbf2', '-O', 'raw', u'/rhev/data-center/mnt/glusterSD/10.137.30.105:_fs03/5d47a297- a21f- 4587-bb7c-dd00d52010d5/images/750f4184-b852-4b00-94fc- 476f3f5b93c7/3fe43487-3302-4b34-865 a-07c5c6aedbf2'], ecode=1, stdout=, stderr=qemu-img: error while reading sector 12197886: No data available , message=None
The storage domains are all based on gluster. The storage domains that we see this on is configured as dispersed volumes.
Found a way to "fix" the problem. And that is to run dd if=/dev/vda of=/dev/null bs=1M inside the virtual guest. After that we can copy an image or use storage livemigration.
Is this a gluster problem or an vdsm problem? Or could it be something with qemu-img?
