This happening to a number of vm's. All vm's are running and can be stopped and re started. We can read and write data within the vm.
All vms are currently running on a single node gluster file system. I am attempting to migrate to a replica 3 gluster file system when i exprience these issues. The problem always seems to happen when finalizing the move or copy.
If it makes a difference the gluster storage we are coping to and from are dedicated storage servers.

Hi Bryan,
It seems like there was an error from qemu-img while reading sector 143654878 . the Image copy (conversion) failed with low level qemu-img failure:
CopyImageError: low level Image copy failed: ("cmd=['/usr/bin/taskset', '--cpu-list', '0-31', '/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/d776b537-16f2-4543-bd96-9b4cba69e247/e371d380-7194-4950-b901-5f2aed5dfb35/images/9959c6e4-1fb7-455b-ad5e-8b9e2324a0ab/3f4e183b-7957-4bee-9153-9d967491f882', '-O', 'raw', u'/rhev/data-center/mnt/glusterSD/vs-host-colo-1-gluster.altn.int:_desktop-vdi1/f927ceb8-91d2-41bd-ba42-dc795395b6d0/images/9959c6e4-1fb7-455b-ad5e-8b9e2324a0ab/3f4e183b-7957-4bee-9153-9d967491f882'], ecode=1, stdout=, stderr=qemu-img: error while reading sector 143654878: No data available\n, message=None",)
Can you verify those disks are indeed valid? Can you IO to them while attaching them to a running VM?

Hi,
I am trying to rebuild my ovirt environment after having to juggle some hardware around. I am moving from hosted engine environment into a engine install on a dedicated server. I have two data centers in my setup and each DC has a non-routable vlan dedicated to storage.
As i rebuild my setup i am trying to clean up my storage configuration. I am attempting to copy vm's and templates to a dedicated gluster setup. However each time i attempt to copy a template or move a vm, the operation fails. The failure always happens when it is finalizing the copy.
The operation does not happen with all vm's, but seems to happen mostly with vm's created from with in Ovirt, and not imported from vmware.
I have attached the logs from where i was trying to copy to templates to a new Gluster Filesystem
Thanks Bryan

I'm not sure if this is related to the hardware that was juggled, but it seems like the volume has a bad sector and qemu-img reports it. Do you have this volume in another storage domain maybe before the hardware change, so we can eliminate the issue of hardware change. You can also open a bug so it will be easier to track and investigate it: https://bugzilla.redhat.com/enter_bug.cgi?product=vdsm please also attach the engine and vdsm logs. Regards, Maor
