strange NFS+samba problem: hangs on some dirs

[nielchiano]

Hi,

Situation: I run Gentoo (duuhhh). /home is symlink to /mnt/net, which is a NFS mounted partition.
I also run a Windows in VMWare. This windows can access /mnt/net/home/niels using Samba (installed on the NFS server).

Usualy I have no problems, both systems are able to access all files. But recently I discovered strange problems. (note: i recently discovered them DOES NOT mean that everything was fine before).
I haven't found a procedure to reproduce the thing, but I have some idea's what may cause it. This is what usualy happens:

• I get a mail in gentoo, save the attachement on my home partition.
  
• I start windows/VMware to edit the file on the SMB mount
  
• Edit done, save it back.
  
• Try to open it again with gentoo

Sometimes it works, but sometimes I get strange things:

• Konqueror just hangs when I try to open the folder
  
• Bash hangs when I try to ls the folder from it's parrent (I can't remember if I can cd to the forlder or not)
  
• Thunderbird shows me the content of the folder, but when I send the mail it hangs
  

After a reboot of my (gentoo) system, everything works fine. Also, Windows can still read/write all files.

I'm quite sure that it has nothing to do with windows. (I'd like to blame it, but I can't this time... )
I think something like to following happens (correct me!!!)

• samba changes a file
  
• ??? somehow changes the inode number or something
  
• nfs has the directory already in cache/doesn't notice the change
  
• tries to open the moved directory

Strange thing is... normaly directories don't get another inode number... so it can't be this; but can be something similar.

I checked the log's of both my machine and the nfs server (also gentoo), nothing about NFS comes along...

Any idea's?
