Hi,
when I start nfs-server.service on a CentOS 7 system it takes 60 seconds
until the nfsd finally is up. Looking at the process list I see a
process 'systemd-tty-ask-password-agent' running which goes away after
the 60 seconds the startup requires soI suspect something in the startup
process is trying to get a password.
Does anyone have an idea what the reason could be for this and how I can
get rid of this delay?
Regards,
Dennis

I've added some debug options to /etc/sysconfig/nfs and attached the
resulting log. The interesting bit seems to be rpc.mountd:
Jun 18 19:00:58 test systemd: Starting NFS Mount Daemon...
...
Jun 18 19:01:58 test rpc.mountd[2021]: Failed to unregister program

NFSv2/3 locking..
Jun 18 19:01:58 test systemd: Unit rpc-statd.service entered failed state.
Jun 18 19:01:58 test systemd: Started NFS Mount Daemon.
It seems rpc.mountd wants to do something that presumably needs a
password on startup which then times out after 60 seconds.
Any ideas what rpc.mountd could be doing there?

How exactly are you testing that? (What are you using to decide when
nfsd is up?)

Whoops, never mind my previous reply.

Maybe there's some problem with rpcbind?

The nfsd processes show up in the ps output.
After some digging I finally found that the reason for this is a buggy
systemd unit file in RHEL/CentOS 7.
This is a bug in nfs-server.service and he fix is to copy
nfs-server.service to /etc/systemd/system and replace all occurrences of
"rpcbind.target" with "rpcbind.service".
See this bug for reference:
