[ovirt-users] Cannot set storage domain on maintenance

[nicolas at devels.es]

Hi,

We're running ovirt-engine-4.1.5.2-1 and we're trying to set one of the 
storage domains on maintenance in order to remove it, as there's nothing 
left on it besides some templates.

To do so, I open the 'Data Centers' tab, then the 'Storage' subtab, 
select the storage domain and click on 'Maintenance'. When asked for 
confirmation I click OK. After that, this error message is shown:

Error while executing action: Cannot deactivate Storage while there are 
running tasks on this Storage.
-Please wait until tasks will finish and try again.

As far as I know, there are no pending tasks on this storage. The Events 
tab only shows a movement of a disk which has nothing to do with this 
storage domain.

What can I do to solve this?

Thanks.

Nicolás
