Re: autosave/restore software fails

[Andrew Johnson <anj@aps.anl.gov>]

I suggest that those people reporting failures should also include 
information about exactly what their NFS server is - Solaris on SPARC, 
Linux on x86 or PPC, HP-UX etc.  Some NFS version 2 implementations 
(version 2 is what vxWorks speaks) do not guarantee that the client's data 
has been written to non-volatile storage before they reply to an NFS write 
request, and that leads to the danger of data loss and/or corruption if 
the server goes down at the wrong moment.  Sun (who designed the NFS 
protocol) do not permit their NFS servers to lie to clients about this, 
but on some OS's the system administrator can configure the server to lie 
so the client's NFS write operations complete faster.

I guess you should also confirm that you're actually using NFS rather than 
FTP or RSH.
