[ovirt-users] Error while executing action RefreshLunsSize: REFRESH_LUN_ERROR

[vasily.lamykin at MegaFon.ru]

I want to add some space on my LUN.
Previously I added the place simply by pressing the "plus" button in domain management.
Today I have some error with this. I touch "plus" button and get next errors:
In web: "Error while executing action RefreshLunsSize: REFRESH_LUN_ERROR "
In engine.log:

Not all the hosts are seeing the same LUN size.

But on all node's I see same LUN size in `multipath -ll`
How can i repair this problem, and expand lun size in ovirt?
