[ovirt-users] VM/Template copy issue

[Bryan Sockel]

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:

Can you verify those disks are indeed valid? Can you IO to them while
attaching them to a running VM?
