Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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:
On very busy systems all of the 'systemd --user' processes will all echo messages that the primary systemd process does. This creates a massive cascade of logs which is completely unnecessary.
In RHEL 8.3 we added a mount succeeded message and on systems with tons of autofs and users logged in we get every single 'systemd --user' process all echoing the mount succeeded message.
From unit.c in RHEL 8.3.0:
void unit_log_success(Unit *u) {
assert(u);
log_struct(LOG_INFO,
"MESSAGE_ID=" SD_MESSAGE_UNIT_SUCCESS_STR,
LOG_UNIT_ID(u),
LOG_UNIT_INVOCATION_ID(u),
LOG_UNIT_MESSAGE(u, "Succeeded."));
}
Version-Release number of selected component (if applicable):
RHEL 8.3 systemd-239-41.el8_3.1.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Have a user logged in and mount a filesystem
Actual results:
systemd overwhelms logs on very busy systems.
Expected results:
Only the primary systemd process should indicate that these mounts succeeded or this should be hidden behind a debug or other logging.
Additional info:
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
