[Users] VM wont restart after some NFS snapshot restore.

I have some VM's that live on NFS share. Basically, I had to revert the VM disk to a backup from a few days ago. So I powered the VM down, copied over the following files 039a8482-c267-4051-b1e6-1c1dee49b3d7 039a8482-c267-4051-b1e6-1c1dee49b3d7.lease 039a8482-c267-4051-b1e6-1c1dee49b3d7.meta 8d48505d-846d-49a7-8b50-d972ee051145 8d48505d-846d-49a7-8b50-d972ee051145.lease 8d48505d-846d-49a7-8b50-d972ee051145.meta and now when I try to power the VM, it complains 2013-Oct-02, 22:02:38 Failed to run VM zabbix-prod-01 (User: admin@internal). 2013-Oct-02, 22:02:38 Failed to run VM zabbix-prod-01 on Host tss-tusk-ovirt-01-ovirtmgmt.tusk.tufts.edu. 2013-Oct-02, 22:02:38 VM zabbix-prod-01 is down. Exit message: 'truesize'. Any ideas on how I could resolve this? Perhaps a better way of approaching the restore on a filesystem level? I see the following the vsdm.log Thread-7843::ERROR::2013-10-02 22:02:37,548::vm::716::vm.Vm::(_startUnderlyingVm) vmId=`8e8764ad-6b4c-48d8-9a19-fa5cf77208ef`::The vm start process failed Traceback (most recent call last): File "/usr/share/vdsm/vm.py", line 678, in _startUnderlyingVm self._run() File "/usr/share/vdsm/libvirtvm.py", line 1467, in _run devices = self.buildConfDevices() File "/usr/share/vdsm/vm.py", line 515, in buildConfDevices self._normalizeVdsmImg(drv) File "/usr/share/vdsm/vm.py", line 408, in _normalizeVdsmImg drv['truesize'] = res['truesize'] KeyError: 'truesize' Thread-7843::DEBUG::2013-10-02 22:02:37,553::vm::1065::vm.Vm::(setDownStatus) vmId=`8e8764ad-6b4c-48d8-9a19-fa5cf77208ef`::Changed state to Down: 'truesize' Any help would be really nice, thanks! -- Usman
