[ovirt-users] Error deleting template

Hi all, I have a problem deleting a template from admin portal. In file /var/log/vdsm/vdsm.log (on SPM hypervisor) I got: jsonrpc.Executor/4::ERROR::2016-04-27 10:19:57,122::hsm::1518::Storage.HSM::(deleteImage) Empty or not found image <disk uuid> in SD <storage domain UUID> [...] Looking in the (data) storage domain the disk with that UUID doesn't exists. It seems I reached an inconsistent state between engine database and images on disk. Is there a (safe) way to rebuild a consistent situation? Maybe deleting entries from database? My setup is based: manager RHEV 3.5.8-0.1.el6ev hypervisors: RHEV Hypervisor - 7.2 - 20160328.0.el7ev Thanx in advance, Giulio
