[ovirt-users] Problem putting node into maintenance

Hello, node (plain CentOS) in 4.3.1. I have to update to 4.3.2, but when I try to put into maintrnance I see this message that preents me from doing it... " Error while executing action: Cannot switch Host ov200 to Maintenance mode. Image transfer is in progress for the following (2) disks: a97c70c1-512f-4b45-818d-9c32150b5aa1, f1135ee1-ef35-4b00-b81a-a983228323c9 Please wait for the operations to complete and try again. " It seems no operation are currently in place. I had uploaded two iso images to a data (iSCSI based) domain and I noticed that the transfer completed but inside disks page they remained with "completed" status and not ok. I removed them but still the message How to fix? Thanks, Gianluca
