Public bug reported: I recently just did a from-scratch install of Ubuntu 20.04 server edition and ran into issues with Open vSwitch and ZFS. I attempted to use ZFS for all of /var only to find that ovsdb-server pre-empted my ZFS /var mount which caused it to crash when trying to read its configuration DB at/var/lib/openvswitch/conf.db After much troubleshooting, the problem basically boils down to ovsdb- server.service needing a requirement on local-fs.target
I then found a blog post on Open Cloud Blog (https://www.opencloudblog.com/?p=240) that contained a fix: The "After" line /lib/systemd/system/ovsdb-server.service needs the following changes: [Unit] Description=Open vSwitch Database Unit After=syslog.target network-pre.target dpdk.service local-fs.target Before=network.target networking.service PartOf=openvswitch-switch.service DefaultDependencies=no [Service] LimitNOFILE=1048576 Type=forking Restart=on-failure EnvironmentFile=-/etc/default/openvswitch ExecStart=/usr/share/openvswitch/scripts/ovs-ctl \ --no-ovs-vswitchd --no-monitor --system-id=random \ start $OPTIONS ExecStop=/usr/share/openvswitch/scripts/ovs-ctl --no-ovs-vswitchd stop ExecReload=/usr/share/openvswitch/scripts/ovs-ctl --no-ovs-vswitchd \ --no-monitor restart $OPTIONS RuntimeDirectory=openvswitch RuntimeDirectoryMode=0755 ** Affects: openvswitch (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1887177 Title: ovsdb-server.service needs a depedency on local-fs.target To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1887177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
