And now I have two popups with an error somewhat alike:

    Uncaught exception occurred. Please try reloading the page. Details:
    (TypeError) __gwt$exception: <skipped>: Cannot read property
    'firstChild' of null
    Please have your administrator check the UI logs

While watching the gluster volumes rebuilding on 
https://ovirttest.netbulae.test/ovirt-engine/webadmin/?locale=en_US#volumes

I put one gluster server in maintenance and after the volumes came up 
again, I got the error without clicking anything
