Description Robert McSwain 2019-11-20 20:28:44 UTC

Issue:

Failure of "ovs-appctl -t /var/run/openvswitch/ovn-controller.$pid.ctl" to exit causes logrotate run to hang and cron.daily to lock indefinitely. 

Found that logrotate run from cron.daily is hanging on running /etc/logrotate.d/openvswitch, and more specifically on rotating portion of rotating the ovn-controller log which calls for `ovs-appctl -t "$ctl"  vlog/reopen 2>/dev/null" 

This is only failing for the ovn-controller, not ovsdb-server or ovs-vswitchd. 

/var/log/cron contains multiple entries containing "Job `cron.daily' locked by another anacron - skipping


Steps to Reproduce:
Run
# ovs-appctl -t /var/run/openvswitch/ovn-controller.$pid.ctl 

Observe that this fails on any hypervisor it's run on, even when run manually, hanging indefinitely.

Other notes:
There do not seem to be any logs at this time showing why this fails. Any additional debugging steps would be appreciated.

I am unsure about the FDB version, yum says:
2.9.0-104.el7fdp

Comment 12 Flavio Leitner 2024-03-12 14:33:23 UTC

Hi,
The Open vSwitch 2.9 is no longer supported.
If this issue is still relevant, please open a new ticket using a supported Open vSwitch version at https://issues.redhat.com/projects/FDP
Thanks
