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 Yongcheng Yang 2022-04-08 14:58:48 UTC 
Description of problem:

The 8.4 Bug 1872310 introduced a new mount option 'softreval' but it cannot be found from current man pages.

We may need this upstream patch:
commit b5381c96298d75ba66625a007e2390e2b501850d
Author: Trond Myklebust <trond.myklebust>
Date:   Wed Jan 29 10:45:39 2020 -0500

    manpage: Add a description of the 'softreval' / 'nosoftreval' mount option


Btw after mounting with softreval, I can't see it from the mount options list. Don't know if this is as expected. 
E.g.
# mount localhost:/export_test/ /mnt_test8/ -o softreval
# nfsstat -m
/mnt_test8 from localhost:/export_test
 Flags: rw,relatime,vers=4.2,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp6,timeo=600,retrans=2,sec=sys,clientaddr=::1,local_lock=none,addr=::1

# nfsstat -m | grep soft
# mountstats /mnt_test8/ | grep soft
# rpm -q nfs-utils
nfs-utils-2.3.3-51.el8.x86_64

       softreval / nosoftreval
                      It is possible to combine softreval with the soft mount option, in which case operations that cannot be served up from cache will  time  out  and  return  an  error  after  retrans
                      Note: the default mount option is nosoftreval which disallows fallback to cache when revalidation fails, and instead follows the behavior dictated by the hard or soft mount option.
