dtrace discuss - May 2007 - what files are being used from a NFS server perspective

I''m curious to know what files are being used from a NFS server 
perspective.  I''m unable to trace the client because it is in the boot 
phase.  Looking at the io provider, I believe it does not allow you to 
look at what files are being requested.  That would lead me to the fbt 
provider.  Does anyone know what fbt provides the file handle for NFS 
client request on the NFS server.

Thanks
Dave

Hi David, 
Check out /usr/demo/dtrace/iosnoop.d

-r

Hi

this may be just what you are looking for, not sure what version of Solaris
you are using.

From some of my testing iosnoop.d does not provide all the file names 
the client may touch when you run iosnoop.d on the nfs server but only 
some very small subset.  I assume this is because the IO provider may 
not handle requests for metadata.  So I''m still trying to investigate 
maybe a fbt that shows the files being passed via file handle.

Thanks

Dave
