Description Andy Adamson 2011-10-19 13:34:10 EDT

Description of problem: Customers and developers using rpcdebug cannot turn on
pnfs debugging. 


Version-Release number of selected component (if applicable):
RHEL 6.2 beta 2.6.32.209.el6


How reproducible:
100%


Steps to Reproduce:
1.run rpcdebug -vh
2.
3.
  
Actual results:

for the nfs module, no flag for pnfs

Expected results:

Expect a pnfs flag option


Additional info:

NFSDBG_PNFS and NFSDBG_PNFS_LD should be activated with an rpcdebug nfs 
module pnfs flag.

This will allow more pin-point debugging of pNFS related client problems.

hi Steve,
Since I don't have pNFS environment, can I use modinfo or any else command to check the result?

Hello,

Well pNFS is a tech preview RHEL6.2 which means it not officially 
supported because tech previews don't go through our normal 
QE process... but I have outlined how to set up pNFS env 
in  https://bugzilla.redhat.com/show_bug.cgi?id=746839#c2

Now how I tested this was to do a 'rpcdebug -m nfs -s pnfs'
then cat /proc/sys/sunrpc/nfs_debug to make sure it had
the appropriate value. In this case the value would be 4096.
