Description Natalie Gavrielov 2017-03-26 13:23:40 UTC

Following issue #1419853:

-----------------------------------------------------------------------------
Detecting whether the daemon is running on an host (and use the host that has this running daemon to perform the upload/download) will help solving bug 1419853.
-----------------------------------------------------------------------------

+++ This bug was initially created as a clone of Bug #1419853 +++

Description of problem:
Try to upload an image using the GUI, when one of the host's ovirt-imageio-daemon is down and the other one is up - operation fails and the disk is in "paused by the system" status.

Version-Release number of selected component:

Engine:
ovirt-engine-4.1.0.3-0.1.el7.noarch
ovirt-imageio-common-1.0.0-0.el7ev.noarch
ovirt-imageio-proxy-1.0.0-0.el7ev.noarch

Hosts:
vdsm-4.19.4-21.git310b0a0.el7.centos.x86_64
ovirt-imageio-common-1.0.0-1.el7.noarch
ovirt-imageio-daemon-1.0.0-1.el7.noarch


How reproducible:
100% (2 out of 2)

Steps to Reproduce:
Have an environment with two hosts - one with ovirt-imageio-daemon running and the other daemon not.
Try to upload an image using the UI.

Actual results:
The transfer failed:
engine.log:

Expected results:
For the upload to succeed - since there is another host with a daemon running. 

Additional info:
Tried to resume the upload twice, first time failed with the same error, second time succeeded - since it used the other daemon.
