[ovirt-users] supervdsmd IOError to /dev/stdout

[Yaniv Bronheim]

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!
