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 of problem:
systemctl nfs reload-or-try-restart (service nfs force-reload) return fail if the nfs service is not running. 
For the option "reload-or-try-restart/force-reload" is to "Reload one or more units if they support it. If not, restart them instead. This does nothing if the units are not running" from the systemctl man page.

Version-Release number of selected component (if applicable):
RHEL-7.1

How reproducible:
100%

Steps to Reproduce:
1.service nfs stop
2.service nfs force-reload

Actual results:
[root@hp-dl580g7-03 tools]# service nfs stop
Redirecting to /bin/systemctl stop  nfs.service
                           ^^^^^^^^^ stop the nfs service

Expected results:
The "reload-or-try-restart/force-reload" option does nothing when the nfs service is not running.

This act the same on both rhel-7.0 and rhel-7.0 but not reprodoced on rhel6

It works just fine for me
rhel7# /bin/systemctl force-reload  nfs.service
rhel7# /bin/systemctl force-reload  nfs-server


also, what exactly is this test testing?

please sop the nfs.service, and then test using the above "force-reload" command

Test the force-reload when the nfs.service is not running.

And from man page of systemctl(1):
reload-or-restart PATTERN...
           Reload one or more units if they support it. 
           If not, restart them instead. If the units are
           not running yet, they will be started.

Ok I see the error:

# systemctl stop nfs
# systemctl force-reload nfs
Job for nfs-server.service invalid.

systemctl -l status nfs reports
  Unit nfs-server.service cannot be reloaded because it is inactive

and when nfsd is loaded things work just fine
# systemctl start nfs
# systemctl force-reload nfs

So I'm thinking that manpage is wrong when it talks about
restarting the unit...
Comment 9 Lukáš Nykrýn 2016-10-11 11:18:18 UTC 
Problem here is that the reload action is designed for the running daemons, it basically means that it should reload its configuration. 

nfs-server is not a daemon, it is oneshot service (with RemainAfterExit=yes) and to be honest I am quite surprised that reload action are allowed there at all.

I will reassign this to systemd, we need to look what we should do in those cases.
