Description of problem:
ERROR:ovirt_hosted_engine_ha.agent.agent.Agent:Error: 'Connection to storage server failed' - trying to restart agent

I've followed reproduction steps described in https://bugzilla.redhat.com/show_bug.cgi?id=1337711 and after host was rebooted got this error and engine failed to get started.

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

Red Hat Enterprise Linux Server release 7.2 (Maipo)
Linux version 3.10.0-327.22.1.el7.x86_64 (mockbuild.eng.bos.redhat.com) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-4) (GCC) ) #1 SMP Mon May 16 13:31:48 EDT 2016
Linux 3.10.0-327.22.1.el7.x86_64 #1 SMP Mon May 16 13:31:48 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux

Engine was deployed using rhevm-appliance-20160602.0-1.el7ev.noarch.

How reproducible:
100%

Steps to Reproduce:
1. Get RHEVM 3.6.7 in Hosted Engine environment.
2. Edit HE VM, aka manager, through the Admin Portal and add additional vnic to it.
3. The vnic is added successfully, the guest OS sees this and all good.
4. Reboot the host.

Actual results:
When host boots up, the engine fails to get started by the agent.

Expected results:
Engine should get started by the agent.

Additional info:
sosreport from host is attached.

In my case it's not RHEVH, it's RHEL, please consider separating these two issues.
Comment 4 Simone Tiraboschi 2016-06-08 12:49:56 UTC 
Nikolai, as a workaround to save the deployment you can edit /etc/ovirt-hosted-engine/hosted-engine.conf 
changing from 'mnt_options=None' to 'mnt_options='

The fix is generic on hosted-engine-setup
