Description Simone Tiraboschi 2018-02-08 12:58:13 UTC
Description of problem:
Trying to deploy hosted-engine on iSCSI with multi-path on the vintage flow,
the setup could fail if just one of the path to the storage server is down.

In interactive mode the setup will check active paths at customization stage,
but if the path list is provided via answer file (from cockpit for instance) the setup will try consume all of them failing if just a path is down with:

Version-Release number of selected component (if applicable):


How reproducible:
100%

Steps to Reproduce:
1. try to deploy hosted-engine from cockpit specifying more than one iSCSI portal separating them with a comma (192.168.1.125,192.168.2.125,192.168.3.125)
2. one portal can be reached but at least one of the remaining is down
3.

Actual results:
The setup fails with
  RuntimeError: Connection to storage server failed
also if just one of the iSCSI portal is not reachable

Expected results:
The setup will emit a warning about failed paths and it will continue if at a path is working
