Comment 3 Elad 2014-11-24 15:48:09 UTC
This is not the same issue.
This bug was opened for storage domain extension described a scenario in which a virtual disk is resized

Comment 4 Piotr Kliczewski 2014-11-24 16:03:10 UTC
I can see in the log that error was thrown during invocation of the same verb:

Calling 'Host.getDevicesVisibility'

This is the same verb which failed in disk resize bug.

Comment 5 Piotr Kliczewski 2014-11-24 16:12:50 UTC
Why do you think it is different bug?

Comment 6 Oved Ourfali 2014-11-25 07:59:15 UTC
Piotr - if the fix was already applied, then let's move it to MODIFIED.
Elad - once it will move to ON_QA, verify this use case.

Comment 7 Elad 2014-12-16 09:31:14 UTC
FC domain extenstion succeeds while using JSON-RPC

Veirified using rhev 3.5 vt13.3
