Description of problem: This message is being printed on every gfs2 umount: Nov 20 14:56:20 host-061 dlm_controld[12599]: 1965 cpg_dispatch error 9 Version-Release number of selected component (if applicable): dlm-4.0.2-2.el7.x86_64 kernel-3.10.0-52.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. mount gfs2 2. umount gfs2 3. observe the message in syslog Actual results: Nov 20 14:56:20 host-061 dlm_controld[12599]: 1965 cpg_dispatch error 9 Expected results: no error Additional info: there does not seem to be any negative effect of the error, it's just scaring me in the logs :)
This is the method I've always used to leave a cpg: 1. cpg_leave() 2. cpg_dispatch(ALL) 3. within the final confchg callback, call cpg_finalize() cpg_dispatch is now returning an error for this usage. If that's what corosync intends to do now, then I'll remove the error message.
Is error 9 now intentionally returned in the example above?
Yes, it's a 'normal' return value if cpg_finalize() is called within a callback while cpg_dispatch is active. So it can be safely ignored.
This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux.
So far as I can tell this looks like it is pretty minor - so moving to 7.2.
