HELP!!!

I just did this, but now my storage isn't showing up!  According to
"mount", only the HE domain is mounted, but none of my other domains
mounted.  Running 'hosted-engine --connect-storage' does not seem to mount
the storage domains.

If I bring the engine up, it still wont access those domains.  And indeed,
now the host is showing up as non-responsive to the engine.

on the host, I see:

[root@ovirt-0 ~]# hosted-engine --vm-status


--== Host 1 status ==--

Status up-to-date                  : True
Hostname                           : OVIRT-0{.dom.ain}
Host ID                            : 1
Engine status                      : {"health": "good", "vm": "up",
"detail": "up"}
Score                              : 3400
stopped                            : False
Local maintenance                  : False
crc32                              : 76ac9280
Host timestamp                     : 985
Extra metadata (valid at timestamp):
        metadata_parse_version=1
        metadata_feature_version=1
        timestamp=985 (Fri Nov 25 11:35:39 2016)
        host-id=1
        score=3400
        maintenance=False
        state=EngineUp
        stopped=False

So the host seems to think the engine is up.

I can't mount the storage from the UI because the engine claims the host
is non-responsive.  Not surprisingly, this appears to be due to a
networking issue that I didn't have before the update.  Indeed, the engine
can't reach the host, even though I can reach both (and the host can reach
the engine).  Did the host update somehow change the iptables
configuration?  It doesn't look like it.  But I'm not sure why the network
isn't working now when it was working before the update.

So, now what do I do?  I suppose I can check my host backup from last
night and see if I can see anything different in the vdsm configs?

There are two problems to solve:

1) Host doesn't mount my storage
2) Engine can't reach host via network.

HELP!
