<p>Dear colleagues,</p>
<p>after upgrade to 1.7.0 (Ubuntu 18.04):</p>
<pre># dpkg -l |grep linstor
ii linstor-client 1.1.0-1ppa1~bionic1 all Linstor client command line tool
ii linstor-common 1.7.0-1ppa1~bionic1 all DRBD distributed resource management utility
ii linstor-controller 1.7.0-1ppa1~bionic1 all DRBD distributed resource management utility
ii linstor-satellite 1.7.0-1ppa1~bionic1 all DRBD distributed resource management utility
ii python-linstor 1.1.0-1ppa1~bionic1 all Linstor python api library</pre>
<p>I see the following strange behaviour (note - there are no
iptables filters on the hosts; everything else has no connectivity
issues; cmp3 is exactly the same as cmp1 and cmp2; there are no
errors in linstor controller/satellite logs) - without any actions
from my side, warning about connectivity to cmp3 floats between
different pools:<br>
</p>

<p>Any ideas what and why is this and whether this can impact
something?</p>
<p>Thank you.<br>
