Strange NFS problem

So I am a bit hungover today so maybe I did something stupid but I can't work out what it was.
Seriously, I didn't change or touch anything. All I did was a `mpd --create-db` and then my nfs would no longer mount. When I a `sudo mount -a` I got this message.

[ty@donna ~]$ sudo mount -a
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
mount.nfs: an incorrect mount option was specified

In /var/log/errors.log there is this.

Jul 25 12:00:44 donna rpcbind: cannot get local address for udp: Servname not supported for ai_socktype
Jul 25 12:00:44 donna rpcbind: cannot get local address for tcp: Servname not supported for ai_socktype
Jul 25 12:00:44 donna rpcbind: cannot get local address for udp6: Servname not supported for ai_socktype
Jul 25 12:00:44 donna rpcbind: cannot get local address for tcp6: Servname not supported for ai_socktype

Restarting rpcbind did nothing. All I could do to get it to start again was add `nolock` to the fstab entry.

I swear I didn't do anything, not even a system upgrade. And it was working before I ran `mpd --create-db` because I was listening to music before I did it.

Very strange. Any ideas why this happened?

Re: Strange NFS problem

so problem in new package iana-etc. because /etc/services was removed from filesystem package
in first look services in old-filesystem and new iana-etc does not diff in rpc part, but if I change /etc/services by adding rpcbind 111/{tcp|udp} it works.

I dont know is it bug or not

Re: Strange NFS problem

Shouldn't this rather be filed as a bug report too? Something is out of sync between our packages and the iana stuff at least...

Edit: and this is [Testing], so moving to the appropriate subforum.

Re: Strange NFS problem

Already reported when I finally figured out what was causing it.

http://bugs.archlinux.org/task/20273

@vanDake: the layout of the /etc/services file allows for aliases. Rather than replacing sunrpc, alias rpcbind to it. I had suspected this, but it didn't initially work (got some socket in use errors). Seems to have just been rpcbind being a little slow to really unbind itself.

edit: ...and you posted the alias on the bug report.
