[clue-tech] nfs frustrations

[Angelo Bertolli]

Ok so none of the options on an NFS mount do what I want it to do.  
Maybe automount is the only solution, but for regular nfs...

1) There doesn't seem to be any way to get the system to automatically 
unmount a filesystem that is not responding

2) There doesn't seem to be any way to tell NFS to fail within 1 
minute.  I know the maximum retrans timeout is supposed to be 60 
seconds, but after tweaking it

When a mount is unavailable (I'm using ls to test) ...
    - soft/hard doesn't seem to make any difference (I'm using ro,noexec)
    - retrans, timeo, retry don't seem to make any difference no matter 
what settings I use
    - I've tried at least 10 combinations of the above, and ls returns 
with an IO error within 3 - 5 minutes every time.


Oh well.  We're using nfs3.  Should I expect different behavior from nfs4 ?
