Occurrence on the latest MOS 9.0 swarm run (ISO build fuel-9.0-mos-368-2016-05-17)

[Sergey Shevorakov (sshevorakov)]

Raised priority to High, since it fails 1 Swarm TC.

[Ksenia Svechnikova (kdemina)]

@Sergey
When you add swarm-fail tag and raise priority, please add any information about what TC is failed by this issue. As for now it's not clear what Milestone it affects and at what test should we look.

[Sergey Shevorakov (sshevorakov)]

Here is the case: https://mirantis.testrail.com/index.php?/tests/view/6590094

[Sergey Shevorakov (sshevorakov)]

I was talking about 9.0, since the bug appeared in 9.0 ISO #423 Swarm results.

[Ksenia Svechnikova (kdemina)]

Reassign 9.0 for vshypyguzov, same as it's in 10.0

In case if it's not qa issue, please reassign to the proper team

[Andrey Sledzinskiy (asledzinskiy)]

As it was stated there is no connectivity to the node so it's not qa issue

[Dmitry Pyzhov (dpyzhov)]

Guys, please don't drop bugs. It is either issue with QA test or with CI configuration or with deployment or with OSTF test. Please find a root cause and move to the proper team.

[Volodymyr Shypyguzov (vshypyguzov)]

Moving to Invalid since it wasn't reproduced for a long time

[Timofey Durakov (tdurakov)]
