Dear colleagues,
after upgrade to 1.7.0 (Ubuntu 18.04):
# 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
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:

Any ideas what and why is this and whether this can impact something?
Thank you.
