[ovirt-users] unable to put node 4.3.0 host into maintenance for upgrade, Image transfer in progress

When trying to put a node 4.3.0 into maintenance, I get the following error: -- Error while executing action: Cannot switch Host winterfell.psc.edu to Maintenance mode. Image transfer is in progress for the following (2) disks: 8d130846-bd84-46b0-9a45-b6a2ecf66865, 35fd6f8f-65f5-49e7-ae5a-9b10c5c0a38f Please wait for the operations to complete and try again. -- Attached is an image of the disks UI for those, showing their status. From the engine UI there seems to be no way to clean out "completed" or "failed" uploads/downloads. I tried running the taskcleaner.sh and unlock-entity disk UUIDs but I still get the error. Not sure what to try next...
