Now looked at the source, and I do not think there is a way. It might
be useful to add one, though - and might be not too hard - perhaps
something like this (didn't test):

https://gerrit.ovirt.org/89528

That said, I think it's about time we change the text(s) to imply
that we use this gateway to test network connectivity with ping,
so do not really need to be a gateway, but do need to reliably reply
to pings, and if we do have places where we use it as a gateway,
we should simply ask two questions, or at least allow overriding
in the config file.

[ovirt-users] Ping::(action) Failed to ping x.x.x.x, (4 out of 5)

[i...@linuxfabrik.ch]

Hi all,

we randomly and constantly have this message in our /var/log/ovirt-
hosted-engine-ha/broker.log:

/var/log/ovirt-hosted-engine-ha/broker.log:Thread-1::WARNING::2018-03-
27 08:17:25,891::ping::63::ping.Ping::(action) Failed to ping x.x.x.x,
(4 out of 5)

The pinged device is a switch (not a gateway). We know that a switch
might drop icmp packets if it needs to. The interesting thing about
that is if it fails it fails always at "4 out of 5", but in the end (5
of 5) it always succeeds.

Is there a way to increase the amount of pings or to have another way
instead of ping?


Regards
Markus
