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.

Additional info:

--- Additional comment from Yin.JianHong on 2015-06-17 23:28:15 EDT ---

seems because the rpcbind service not start.
  nfs-utils/systemd should auto start the rpcbind service.

Got it:

Can confirm. I need to start rbcbind by hand.

I have nfs-utils-1.3.2-9.fc22.x86_64 and I still get failures to start NFS on system boot.

--- Additional comment from mario on 2016-03-20 17:32:08 EDT ---

Fedora 22, nfs-utils-1:1.3.3-6.fc22.i686 such that 'service nfs start' always fails.
Downgrade to nfs-utils-1:1.3.2-4.fc22.i686 fixes it.

--- Additional comment from mario on 2016-03-20 17:37:32 EDT ---

Correction (missing rc3): nfs-utils-1:1.3.3-6.rc3.fc22.i686.
Also: nfs-utils.x86_64-1:1.3.3-6.rc3.fc23 works fine on a Fedora 23 machine.

I just update f22 to latest upstream release which hopefully 
takes care of this problem

at link, I see some update for f23, not for f22, am I wrong?

During QCI 1.0 testing, QE saw this in stage...
um list nfs-utils
Loaded plugins: product-id, search-disabled-repos, subscription-manager
Installed Packages
nfs-utils.x86_64                                                                         1:1.3.0-0.21.el7_2                                                                          @rhel-7-server-rpms

Can we get the newer nfs-utils version (>= 1.3.2) to RHEL 7 to resolve this?

Workaround [As listed above]:
1) systemctl restart rpcbind
2) systemctl restart nfs-server
