[Bug 1906922] Re: Unpredictable behaviour on conflicting flow actions
Frode, this solves the packet loss issue I saw previously. I marked this field crit, as we don't have a workaround, and would be grate to make it through the SRU process intro stable branch for UCA/Ussuri/Bionic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1906922 Title: Unpredictable behaviour on conflicting flow actions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ovn/+bug/1906922/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1827690] Re: [19.04][stein] barbican-worker is down: Requested revision 1a0c2cdafb38 overlaps with other requested revisions 39cf2e645cba
After additional debug and research I can confirm the issue is the result of a race-condition situation when multiple barbican-worker units trying to populate the database with schema data simultaneously and upgrade the alembic version. As a result the barbican-worker service will stop because it is trying to recreate tables already created by other worker units. I applied the following manual steps as workaround: 1, stop all barbican-workers, stop jujud agent 2, drop db tables 3, clean up alembic db change states if present: rm -rf /usr/lib/python3/dist-packages/barbican/model/migration/alembic_migrations/versions/*_db_change.py files 4, start barbican-worker on a single unit (populates the db tables to head revisions) 5, restart all barbican-workers, start jujud agent as a result each units must be on the same db revision: $ juju run --application barbican 'barbican-db-manage current -V | grep Revision' - Stdout: |2 Revision ID: 39cf2e645cba UnitId: barbican/0 - Stdout: |2 Revision ID: 39cf2e645cba UnitId: barbican/1 - Stdout: |2 Revision ID: 39cf2e645cba UnitId: barbican/2 The root cause of the problem is the default implementation of barbican- worker services, because they are populating the data after service start, this can lead to the race condition situation. A proper permanent charm fix should be: 1, As [1] mentions in the Install and configure components / 3. Populate the Key Manager service database section, the charm should set the db_auto_create to false in the /etc/barbican/barbican.conf file. 2, the leader charm populates the database 3, start the barbican-worker services after the leader finished with db schema upgrade.

[Bug 924013] Re: VPN DNS only works for IP, not names
I experienced the same issue. After sucessfull OpenVPN connection /var/run/nm-dns-dnsmasq.conf contains the following: server=/10.in-addr.arpa/10.1.106.7 server=192.168.0.1 server=192.168.3.2 This 10.in-addr.arpa prefix appears only when "Use this connection only for resources on its network" checkbox was turned on at IPV4 routes page of VPN configuration window. Syslog contains the following: ... Mar 23 09:41:35 shakira dnsmasq[4138]: using nameserver 10.1.106.7#53 for domain 10.in-addr.arpa ... Finally, I found, that the OpenVPN server was not pushing down the domain suffix. After inserting the proper "dhcp-option DOMAIN" entry into openvpn server configuration, it started to work. openvpn server.conf: ... push "dhcp-option DNS 10.1.106.7" push "dhcp-option DOMAIN dev.xxx.domain.com" ... /var/run/nm-dns-dnsmasq.conf: ... server=/devzone.cloud.xemeti.com/10.1.106.7 ... So I think it is not a client side bug, just a server side configuration requirement.
