Hi Ilya,
I’ve got question regarding upgrade of clustered ovsdb-servers from 3.1 to 3.2+
version.
ovsdb(7) states that the recommended path for upgrade is to upgrade
ovsdb-servers one-by-one and that after upgrade ovsdb-server should be started
with option --disable-file-no-data-conversion and

Hi,
There is a patchset under review [1] for this functionality.
You can try this out locally or wait it to be accepted in upstream.

Hi Krzysztof,
talking about OVN < 23.09:

Hi Ilya,
I’m wondering whether there are possible configuration parameters for ovsdb

My cluster experiencing issues where relay disconnects from main cluster due to

Hi,
since you’ve configured multiple LRPs with GW chassis, you must supply
logical_port for NAT rule. Did you configure it?
You should see appropriate message in ovn-northd logfile.
logical_port: optional string
The name of the logical port where the logical_ip resides.
the
NAT rule.

Hi Ilya,
let me jump into this thread.
Right now I’m debugging the behaviour of ovn (22.09.x) and ovsdb-server 3.1.0
where one ovsdb update3 request makes ovsdb-server, which acts as a relay for
OVN Southbound DB with only 5-6 clients connected to it (ovn-controllers,
acting as a central chass
I ran perf record -F99 -p $(ovsdb-server) -- sleep 30 on ovsdb-server process
during CPU spike. perf report result:

Overhead Command Shared ObjectSymbol
58.71% ovsdb-server libopenvswitch-3.1.so.0.0.0
Thanks Ilya for your inputs.

Hi all,
I’ve faced condition in flow lookup where OVS crashes with segmentation
violation because of insufficient stack limit size for ovs-vswitchd daemon.
Below is the reproducer:

OVS is run (should be 2M):

Hi Austin,
There is a special function in northd.c to handle hairpin traffic -
build_vtep_hairpin().
The mentioned flows are not matched due to flow [1], which by default sends all
traffic received from vtep lport to l2lkp table for local delivery.
As you correctly noticed, there is no instance

Hi Sergey,
The LB support for HW VTEP is not implemented. The main trouble is the fact
that HW VTEP device itself cannot modify packets or do whatever with control
plane traffic (answer ARPs, etc.). At least for now.
Additional L3 Gateway chassis can be used to connect routed overlay topologies

Hi George,
do you experience these problems with 22.03 version?
If yes, you may want try patch by Ilya [1], which is a part of 23.09 release.
Shortly, there was a problem where a new datapath in OVN caused a full
re-create of datapath_groups, which results in a huge ovsdb transaction.

Sorry, it first appeared in 23.06.
