Re: [ovirt-users] problem while moving/copying disks: vdsm low level image copy failed

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? /Johan _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
