Problem with mounting NFS on Mac OS X

Recently, I got a problem mounting my NFS shares. A shortcut to the /Volumes/Public placed on the desktop would mount the volume in read-only mode. A go to /Volumes and selecting the Public link would mount it in read-write.

Things I tried first:
-chgrp to guest, admin, 20 (group where my user is)
-chown to guest, myself, admin
-chmod to 777

Once a volume was mounted in read-only mode, it would only come back on read-write mode after a reboot of the NFS client and following the manual process. It must have been a while like this but it went unnoticed as when mounting from an application (not Finder), it would mount correctly.

I tried rebooting the QNAP (shame on me) but it would not change the mounts without rebooting the client.

So what did I learn so far. All NFS mounts are cached on the client. If you know how to clear the cache without rebooting, it would help me.

I also run nfsstat to find a lot of problems. Compared to some production systems, the number of nfs problems is abnormally high. (I will include some statistics to prove my point.)

Spam

Scene: A cafe. One table is occupied by a group of Vikings with horned helmets on. A man and his wife enter.

Man (Eric Idle): You sit here, dear.

Wife (Graham Chapman in drag): All right.

Man (to Waitress): Morning!

Waitress (Terry Jones, in drag as a bit of a rat-bag): Morning!

Man: Well, what’ve you got?

Waitress: Well, there’s egg and bacon; egg sausage and bacon; egg and spam; egg bacon and spam; egg bacon sausage and spam; spam bacon sausage and spam; spam egg spam spam bacon and spam; spam sausage spam spam bacon spam tomato and spam;

Vikings (starting to chant): Spam spam spam spam…

Waitress: …spam spam spam egg and spam; spam spam spam spam spam spam baked beans spam spam spam…

Vikings (singing): Spam! Lovely spam! Lovely spam!

Waitress: …or Lobster Thermidor au Crevette with a Mornay sauce served in a Provencale manner with shallots and aubergines garnished with truffle pate, brandy and with a fried egg on top and spam.

Wife: Have you got anything without spam?

Waitress: Well, there’s spam egg sausage and spam, that’s not got much spam in it.

Wife: I don’t want ANY spam!

Man: Why can’t she have egg bacon spam and sausage?

Wife: THAT’S got spam in it!

Man: Hasn’t got as much spam in it as spam egg sausage and spam, has it?

Vikings: Spam spam spam spam (crescendo through next few lines)

Wife: Could you do the egg bacon spam and sausage without the spam then?

Waitress: Urgghh!

Wife: What do you mean ‘Urgghh’? I don’t like spam!

Vikings: Lovely spam! Wonderful spam!

Waitress: Shut up!

Vikings: Lovely spam! Wonderful spam!

Waitress: Shut up! (Vikings stop) Bloody Vikings! You can’t have egg bacon spam and sausage without the spam.

Wife (shrieks): I don’t like spam!

Man: Sshh, dear, don’t cause a fuss. I’ll have your spam. I love it. I’m having spam spam spam spam spam spam spam beaked beans spam spam spam and spam!

Vikings (singing): Spam spam spam spam. Lovely spam! Wonderful spam!

Waitress: Shut up!! Baked beans are off.

Man: Well could I have her spam instead of the baked beans then?

Waitress: You mean spam spam spam spam spam spam… (but it is too late and the Vikings drown her words)

Vikings (singing elaborately): Spam spam spam spam. Lovely spam! Wonderful spam! Spam spa-a-a-a-a-am spam spa-a-a-a-a-am spam. Lovely spam! Lovely spam! Lovely spam! Lovely spam! Lovely spam! Spam spam spam spam!
