[ovirt-users] Bad volume specification after hung migration

We are running 4.0.1.1-1.el7.centos After a frozen migration attempt, we have two VM that after shutdown, are not anymore able to be started up again. Message returned is : Bad volume specification {'index': '0', u'domainID': u'731d95a9-61a7-4c7a-813b-fb1c3dde47ea', 'reqsize': '0', u'format': u'cow', u'optional': u'false', u'address': {u'function': u'0x0', u'bus': u'0x00', u'domain': u'0x0000', u'type': u'pci', u'slot': u'0x05'}, u'volumeID': u'cffc70ff-ed72-46ef-a369-4be95de72260', 'apparentsize': '3221225472', u'imageID': u'3fe5a849-bcc2-42d3-93c5aca4c504515b', u'specParams': {}, u'readonly': u'false', u'iface': u'virtio', u'deviceId': u'3fe5a849bcc2-42d3-93c5-aca4c504515b', 'truesize': '3221225472', u'poolID': u'00000001-0001-0001-0001-0000000001ec', u'device': u'disk', u'shared': u'false', u'propagateErrors': u'off',u'type':u'disk'} Probably this is caused by a wrong pointer into the database that still refer to the migration image-id. If we search within all_disks view, we can find that parentid field isn't 00000000-0000-0000-0000-000000000000 like all other running vm, but it has a value: vm_names | parentid ----------------------+-------------------------------------- working01.company.xx | 00000000-0000-0000-0000-000000000000 working02.company.xx | 00000000-0000-0000-0000-000000000000 working03.company.xx | 00000000-0000-0000-0000-000000000000 working04.company.xx | 00000000-0000-0000-0000-000000000000 broken001.company.xx | 30533842-2c83-4d0e-95d2-48162dbe23bd <<<<<<<<< working05.company.xx | 00000000-0000-0000-0000-000000000000 How we can recover from this ? Thanks in advance Regards, -- Robert ​o​
