Hi guys, When performing live merge, in few cases, we see the following exception: Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 736, in wrapper return f(*a, **kw) File "/usr/share/vdsm/virt/vm.py", line 5278, in run self.tryPivot() File "/usr/share/vdsm/virt/vm.py", line 5247, in tryPivot ret = self.vm._dom.blockJobAbort(self.drive.name, flags) File "/usr/share/vdsm/virt/virdomain.py", line 68, in f ret = attr(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/libvirtconnection.py", line 124, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 1313, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 733, in blockJobAbort if ret == -1: raise libvirtError ('virDomainBlockJobAbort() failed', dom=self) libvirtError: block copy still active: disk 'vdb' not ready for pivot yet That exception observed in following BZs: https://bugzilla.redhat.com/1376580 https://bugzilla.redhat.com/1397122 I am trying to understand what this exception indicates in order to handle it appropriately when thrown by libvirt. Thanks, Ala
