Hi,
Seems like I already bumped in such issue awhile ago -
https://bugzilla.redhat.com/show_bug.cgi?id=1216880
but now I see what's wrong - it happens after failing to read
/etc/vdsm/svdsm.logger.conf for some reason
then we have a bug in our fallback which tries to run
logging.basicConfig(filename='/dev/stdout', filemode='w+',
level=logging.DEBUG)
and this fails while running as systemd daemon
sorry about that. check why it can't load /etc/vdsm/svdsm.logger.conf and
update us
after fixing the access issue check if you can run
logging.config.fileConfig("/etc/vdsm/svdsm.logger.conf" ,
disable_existing_loggers=False)
Then supervdsmd should start properly
I'll reopen the bugzilla and fix the wrong fallback to syslog print
Thanks!

Hi Yaniv,
On this one node, it happened from 3.6 -> 4.0. It persisted after 4.0->4.1.
Current: vdsm-4.19.24-1.el7.centos.x86_64
In systemd override I now have to have:
StandardOutput=null
