systemd: Afters are also needed for the Wants=network-online.target

2017-04-24T15:25:39+00:00

Commit 9d4fc3fb added Wants=network-online.target which
is not enough to ensure the network is completely up
before the NFS server is started. After=network-online.target
is also needed.

systemd: NFS server services should use network-online

2017-04-10T11:21:23+00:00

There has been an number startup problems where parts of
the NFS server fails to start due to DNS and other
parts of the network not be up.

Reading the systemd.special it seems network.target is
a passive unit which does not wait for the entire
network to come up and network-online.target is an
active unit which does wait.

So this adds Wants=network-online.target to all of
the NFS server services

systemd: Fix nfs-mountd dependency on rpcbind

2017-02-15T15:41:59+00:00

Following commit 91da135f - it replaced "rpcbind.target" by "rpcbind.socket" in
some unit files - "rpcbind.socket" should also be added to "nfs-mountd.service"
as a dependency to avoid race conditions.

Usually "rpcbind.socket" is either started as a "sockets.target" dependency, or
as a dependency for "nfs-server.service", when unit files include it in
"BindsTo" or "After". Unfortunately there is a possilibility to have
"nfs-mountd.service" started when the rpcbind socket is not yet created:

systemd[1]: Starting NFS Mount Daemon...
systemd[1]: nfs-mountd.service: Control process exited, code=exited status=1
systemd[1]: Failed to start NFS Mount Daemon.
systemd[1]: nfs-mountd.service: Unit entered failed state.
systemd[1]: nfs-mountd.service: Failed with result 'exit-code'.

Nowadays "nfs-mountd.service" uses "BindTo" directive to "nfs-server.service".
That, per se, doesn't guarantee ordering for NFS server to start rpcbind and for
nfs-mountd to depend on it.

systemd: Remove the nfs-config.service

2016-12-20T18:29:04+00:00

Now that we have /etc/nfs.conf, a lot of configuration can be
read directly.  So nfs-config isn't really needed any more.

Some distributions allow command-line arguments for various
daemons to be set in an environment file (/etc/sysconfig,
/etc/defaults).
Passing these through /etc/nfs.conf is not possible.

Instead, a distro that needs this functionality can create drop-in
files which select the required value.  As no commands are given
default arguments by systemd unit files, the drop-in can just add
distro-specific args.
For example
  /lib/systemd/system/nfs-mountd.service.d/local.conf
   [Service]
   EnvironmentFile=/etc/sysconfig/nfs
   ExecStart=
   ExecStart=/usr/sbin/rpc.mountd $RPCMOUNTDOPTS

Note the need for the empty assignment to remove existing definitions
first.

systemd: Relax dependencies of services

2015-03-19T15:44:16+00:00

Stop depending on basic.target in the daemons which still do;
i. e. add DefaultDependencies=no. This makes it possible to
run NFS during early boot, and helps if you e. g. have /var
on NFS. We don't require much else than local-fs.

systemd: Bind the nfs-mountd service to the nfs-server service

2015-01-15T10:41:27+00:00

Use BindsTo, instead of PartOf, to bind the rpc-mountd
service to the nfs-server service. Its a much tighter
bind than PartOf.

The Partof=nfs-utils.service was not needed.

One side effect of this tighter bond is when rpc.mountd
is stop, that will also bring the nfs server down
as well, due to the Requires=nfs-mountd.service in
the nfs-server service

systemd units: create nfs-config.service as single location to process config.

2014-03-24T20:30:04+00:00

Instead of processing the config information into command lines every
time it might be needed, do it once in a separate service that other
services can Want.

systemd: add nfs-utils.service which can be used to restart everything.

2014-03-24T20:30:04+00:00

With this patch, systemctl restart nfs-utils will restart any
nfs-utils daemons that are currently running, whether there were
started via nfs-server.service, nfs-client.target, or directly by
systemctl.
