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 Anand Buddhdev 2016-08-17 10:28:57 UTC

Description of problem:

When more than one instance of a system unit exist, systemctl reload does not reload all of them, but only the one started last.

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

systemd-219-19.el7_2.12.x86_64

How reproducible:

Always

Steps to Reproduce:
1. create a systemd unit, and a systemd template with an ExecReload option
2. start the main unit and then start one instance from the template
3. try to reload both of them with "systemctl reload myservice\*"

Actual results:

systemd will reload just one services, but twice.

Expected results:

systemd should reload each service once.

Additional info:

Examples:

# ll /usr/lib/systemd/system/knot*
-r--r--r-- 1 root root 179 Aug 17 10:07 /usr/lib/systemd/system/knot.service
-r--r--r-- 1 root root 217 Aug 17 10:07 /usr/lib/systemd/system/knot@.service

# diff /usr/lib/systemd/system/knot*

Comment 1 Anand Buddhdev 2016-08-18 07:07:52 UTC

Hello. I would like to apologise for this report. There isn't a bug. My unit configuration was incorrect, and both were binding to the same control socket, so the reload command was acting on the wrong daemon.
