Backport the patches for this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1968528 It reports: The fix for Bug 1819868 has introduced a new issue related to its implementation of rate limiting. Rate limiting the mount_event_source can cause unmount events to be missed, which leads to mount unit cgroups being leaked (not cleaned up when the mount is gone). The fix for 1968528 can fix the issue we met: During the reboot process of subclouds (either lock-unlock or sudo reboot), unmounting failure messages repeat for a few hundred of times. The patches are listed at: https://github.com/redhat-plumbers/systemd-rhel8/pull/198/commits And they are picked from https://github.com/systemd-rhel/rhel-8/ (branch rhel-8.4.0). Verification: In my test on an AIO-SX lab, the bug appears as: run "sudo reboot" on controller, endless unmounting failure logs printed. Verified that the problem was there during the shutdown phase of a reboot. Reinstalled with a fixed image, and verified that the issue was now gone by doing 5 reboots. Ran sanity on the lab, and verified no new issues seen. Closes-Bug: #1948899 Signed-off-by: Li Zhou <li.zhou@windriver.com> Change-Id: If95932ceead1bea973f2219d3a8d6b04cf0fd5f8 |
