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.

Red Hat Product Errata RHBA-2017:2233 0 normal SHIPPED_LIVE nfs-utils bug fix and enhancement update 2017-08-01 18:19:33 UTC

Description Jonathan Lebon 2016-12-19 21:15:10 UTC 
Description of problem:

systemd fails to mount /var/lib/nfs/rpc_pipefs because it runs before systemd-tmpfiles-setup.service, which creates the file structure there.

Version-Release number of selected component (if applicable):

# rpm-ostree status
State: idle
Deployments:
● rhel-atomic-host:rhel-atomic-host/7/x86_64/standard
       Version: 7.3.1 (2016-11-30 02:14:24)
        Commit: 42cfe1ca3305defb16dfd59cd0be5c539f19ea720dba861ed11e13941423ae86
        OSName: rhel-atomic-host

Steps to Reproduce:
1. Boot up 7.3.1-1.

Actual results:

/var/lib/nfs/rpc_pipefs isn't mounted.

Expected results:

/var/lib/nfs/rpc_pipefs is mounted.

Additional info:

As expected, doing `systemctl restart var-lib-nfs-rpc_pipefs.mount` later works.
Comment 1 Jonathan Lebon 2016-12-19 21:19:10 UTC 
This is also an issue in 7.3.0:

Comment 2 Brent Baude 2016-12-19 21:27:23 UTC 
This is tripping selinux issues in cloud-init and therefore blocking enablement progress on Azure at this point.

Well, it's *one* issue I noticed from your Azure logs. I'm still not sure if it's *the* issue blocking you currently. The machine should boot up fine without that mount succeeding (and it does over here).
Comment 4 Brent Baude 2016-12-19 22:57:59 UTC 
It is tripping an OSError in cloud-init; hence the failure.  Would be good to see this resolved so I can eliminate it as root cause and so forth
Comment 6 Jonathan Lebon 2016-12-20 16:06:15 UTC 
OK right, we need the same fix as upstream in https://bugzilla.redhat.com/show_bug.cgi?id=1219871 here:

http://pkgs.fedoraproject.org/cgit/rpms/nfs-utils.git/commit/?id=feea4f146dc282fcea12feb8085e7bd9ff7abd6a

Transferring to nfs-utils component.
