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.

Oops, I think I added a RHEL-7 patch to RHEL-6 that I
shouldn't have for bug 1463004.

* Mon Feb 05 2018 Ian Kent <ikent> - 5.0.5-135
- bz1463004 - Server availability probe broke tunneling nfs via localhost
  - remove some redundant rpc library code.
  - add port parameter to rpc_ping().
  - dont probe NFSv2 by default.
  - add version parameter to rpc_ping().
- Resolves: rhbz#1463004

Fortunately the "dont probe NFSv2 by default" patch is
a one line change so I should be able to drop it without
any side effects.

I'll have a look at it and make a test build.

It looks to me like this change should not cause this problem.
It looks like it should work but we can see that the NFS version
parameter isn't right:
get_nfs_info: called with host nfsserver(10.16.69.154) proto 6 version 0x0

I think version above should be 0x10.
