Bug 1575552

Created attachment 1432544 [details]
volume detail

Description of problem:
In gluster volumes' detail appears repeatedly UI error:

Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : b.b.b is null
Please have your administrator check the UI logs

Version-Release number of selected component (if applicable):
ovirt-engine-webadmin-portal-4.2.3.5-0.1.el7.noarch

How reproducible: always on one specific volume


Steps to Reproduce:
1. add gluster host to engine, prepare LV with thin provisioning on the host
2. create volume in engine from this LV
3. go to volume's detail

Actual results: UI error appears


Expected results: no UI error


Additional info:
The only differences in this volume is, that it's gluster volume with thin provisioning. And no matter if it's Up or Down.
And strange is the '?' in grid column 'Space Used' and in detail:
Capacity:
19.97 GiB total, 65.26 MiB used, 19.91 GiB free
