Ala/Adam, this looks like the same issue as bug 1301709. Please either confirm (and reset the target milestone to 3.6.3 and move the bug to MODIFIED) or issue a fix for 3.6.5. Was able to reproduce without the fix and was able to verify that issue is fixed with the fix. Changing target milestone to 3.6.3 and Moving to MODIFIED. Template creation after live merge on a block storage works as expected. Verified according to the steps described in the description using: vdsm-4.17.23-0.el7ev.noarch rhevm-3.6.3.4-0.1.el6.noarch |
Created attachment 1129333 [details] /var/log/ from hypervisor and engine.log Description of problem: On block storage: After a live snapshot merge tried to create a template from the VM. Template creation failed with: "CopyImageError: low level Image copy failed" Version-Release number of selected component (if applicable): Red Hat Enterprise Linux Server release 7.2 (Maipo) vdsm-4.17.21-0.el7ev.noarch libvirt-daemon-1.2.17-13.el7_2.3.x86_64 qemu-kvm-rhev-2.3.0-31.el7_2.7.x86_64 sanlock-3.2.4-2.el7_2.x86_64 python-2.7.5-34.el7.x86_64 rhevm-3.6.3.2-0.1.el6.noarch How reproducible: Always Steps to Reproduce: 1. Create a VM with 1 preallocated disk resides on iSCSI 2. Create a snapshot 3. Start the VM and delete the snapshot 4. Stop the VM 5. Create a template from the VM Actual results: During live snapshot merge I got this error message: jsonrpc.Executor/4::ERROR::2016-02-22 16:26:22,738::dispatcher::76::Storage.Dispatcher::(wrapper) {'status': {'message': "Volume does not exist: (u'f991e88f-482c-4dc4-af47-7b2456404e13',)", 'code': 201}} Template creation failure: d8859e56-d899-4133-866e-68e87177c5a5::ERROR::2016-02-22 16:28:01,658::task::866::Storage.TaskManager.Task::(_setError) Task=`d8859e56-d899-4133-866e-68e87177c5a5`::Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 873, in _run return fn(*args, **kargs) File "/usr/share/vdsm/storage/task.py", line 332, in run return self.cmd(*self.argslist, **self.argsdict) File "/usr/share/vdsm/storage/securable.py", line 77, in wrapper return method(self, *args, **kwargs) File "/usr/share/vdsm/storage/sp.py", line 1570, in copyImage postZero, force) File "/usr/share/vdsm/storage/image.py", line 866, in copyCollapsed raise se.CopyImageError(str(e)) CopyImageError: low level Image copy failed: ("ecode=1, stdout=[], stderr=['qemu-img: /rhev/data-center/mnt/blockSD/ac6d8268-86f8-42dd-9a68-96b7305303ac/images/53c9e1e9-ee7c-4e51-94e9-02125a000949/bc0ff7ce-183f-4e 59-8429-509d869b4a41: error while converting raw: Device is too small'], message=None",) Tested on NFS, was not able to reproduce. Expected results: Template creation should succeed. Additional info: /var/log/ from hypervisor and engine.log
