[Users] Unable to remove Vdisk and Ovirt UI spams finished messages

So I removed a Vdisk from a powered off VM a few hours ago. The Disk still shows it has a lock on it and the webUI keeps showing this message every 10 seconds or so. 2013-Oct-08, 19:22:09 User <UNKNOWN> finished to remove the disk tuskdb-dev-01_vdisk01_50gb from domain TSS-TUSK-DC_NFS-VM-Stor. 2013-Oct-08, 19:21:59 User <UNKNOWN> finished to remove the disk tuskdb-dev-01_vdisk01_50gb from domain TSS-TUSK-DC_NFS-VM-Stor. 2013-Oct-08, 19:21:49 User <UNKNOWN> finished to remove the disk tuskdb-dev-01_vdisk01_50gb from domain TSS-TUSK-DC_NFS-VM-Stor. 2013-Oct-08, 19:21:39 User <UNKNOWN> finished to remove the disk tuskdb-dev-01_vdisk01_50gb from domain TSS-TUSK-DC_NFS-VM-Stor. 2013-Oct-08, 19:21:29 User <UNKNOWN> finished to remove the disk tuskdb-dev-01_vdisk01_50gb from domain TSS-TUSK-DC_NFS-VM-Stor. I've tried restarting the SPM Hypervisor and the Ovirt Engine. Still no dice. Which host would have the lock? Where should I look for log files? Thanks, Usman
