file locking error (37!) NFS problem

file locking error (37!) NFS problem

[Bernhard Busch]

Hello  NFS Experts


I upgraded  a NFS Server from Suse 8.0 to Suse  8.1.

If  i use the EMAN program (Electron Image Processing Program, cluster 
version) from
a client  with Suse8.0   (the data files are on the fileserver) , i get 
the error message


file locking error (37!) NFS problem

and the application crashes.
Under Suse8.0  (file server) everything is working well.
On the fileserver with Suse8.2
the application also crashes.


Many thanks for every help.

Sincerely 

Bernhard Busch

*IF* the '37' is actually the error code returned by the kernel (in
which case it seems stupid that they don't use 'perror()' to report it
in standard format, but whatever...), then that would just be -ENOLCK
(i.e. the lock failed).

Check that your new server is not firewalling the port that is being
used by lockd. ('rpcinfo -p' will tell you which port that is).

Cheers,
  Trond
