As it turns out, I'd not subscribed to this bug so I didn't get comments after I posted mine. I had to refer back to my own comment to figure out the solution since my NFS server apparently broke earlier this week.
An update to nfs-common (I think that's the package that installs the service files) was pushed out and overwrote the "fix" I'd put in earlier. A more complete fix (after some trial and error) was to create the "override.conf" files for nfs-server and nfs-mountd using: sudo systemctl edit nfs-server (same for nfs-mountd). I copy/pasted the baseline service definitions into the override files and added my own tweaks. With that, the override files I am currently running with are as follows (output from systemctl cat nfs-server and nfs-mountd): ------- # /etc/systemd/system/nfs-server.service.d/override.conf [Unit] Description=NFS server and services DefaultDependencies=no Requires= network.target proc-fs-nfsd.mount Requires= nfs-mountd.service Wants=rpcbind.socket Wants=nfs-idmapd.service After= local-fs.target After= network.target proc-fs-nfsd.mount rpcbind.socket nfs-mountd.service After= nfs-idmapd.service rpc-statd.service Before= rpc-statd-notify.service # GSS services dependencies and ordering Wants=auth-rpcgss-module.service After=rpc-gssd.service rpc-svcgssd.service # start/stop server before/after client Before=remote-fs-pre.target Wants=nfs-config.service After=nfs-config.service BindsTo=rpcbind.service After=rpcbind.service [Service] EnvironmentFile=-/run/sysconfig/nfs-utils ExecStart= Type=oneshot RemainAfterExit=yes ExecStartPre=/usr/sbin/exportfs -r ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS ExecStop=/usr/sbin/rpc.nfsd 0 ExecStopPost=/usr/sbin/exportfs -au ExecStopPost=/usr/sbin/exportfs -f ExecReload=/usr/sbin/exportfs -r [Install] WantedBy=multi-user.target ------ Note the addition of: BindsTo=rpcbind.service After=rpcbind.service ExecStart= ------ # /etc/systemd/system/nfs-mountd.service.d/override.conf [Unit] Description=NFS Mount Daemon DefaultDependencies=no Requires=proc-fs-nfsd.mount After=proc-fs-nfsd.mount After=network.target local-fs.target After=rpcbind.socket BindsTo=nfs-server.service Wants=nfs-config.service rpcbind.service After=nfs-config.service rpcbind.service [Service] EnvironmentFile=-/run/sysconfig/nfs-utils Type=forking ExecStart= ExecStart=/usr/sbin/rpc.mountd $RPCMOUNTDARGS ------ Note the addition of "rpcbind.service" on the "Wants" and "After" lines, as well as the "ExecStart=". It took me a bit to figure out the "ExecStart=" directives were required. As I found out, the ExecStart directive is additive, so the "ExecStart=" directive is required to "clear out" the directive set in the baseline service files. (In other words, the baseline service file is read before override.conf is read). This appears to work for me on Ubuntu 16.04.06. I am not in a position to verify these tweaks work on later versions of Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1590799 Title: nfs-kernel-server does not start because of dependency failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/1590799/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
