Hi,

Maybe you tried to upload/download images, and these are still running.
Go to the disks tab and see if you have Upload/Download operations in progress cancel them.
You have the option to cancel in the Download/Upload buttons.

Regards,
Fred

Hi,

While upgrading host from ovirt 4.1.9 to ovirt 4.2.2, got one ovirt host which I can't move to maintenance mode for the following reason :
2018-05-02 10:16:18,789+02 WARN [org.ovirt.engine.core.bll.MaintenanceNumberOfVdssCommand] (default task-27) [193c3d45-5b25-4ccf-9d2c-5b792e99b9fe] Validation of action 'MaintenanceNumberOfVdss' failed for user admin@internal-authz.

        13152865-2753-407a-a0e1-425e09889d92,$disks_COUNTER 3

I don't know what are those 3 images transfers in progress, there is no VM running on this host.
I try to list old task running on it with the taskcleaner.sh script on the engine : found nothing.

How can I delete or remove those entries ?
