RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Andy Adamson 2011-10-19 17:34:10 UTC 
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.
