[ClusterLabs] Antw: Re: Resource won't start, crm_resource -Y does not help

[Ulrich Windl]

Hi!

My RA actually sends OCF_ERR_ARGS if checking the args detects a problem.
But as the error can be resolved sometimes without changing the args (eg.
providing some resource by other means), I suspect CRM does not handle that
properly. Even after a resource cleanup.

My RA logs any parameter check, and I can see that no parameter check is being
performed...

I also noticed that the "invalid parameter" persists on a node even after
restarting pacemaker on that node.

So:
# crm_resource -r prm_idredir_test -VV start
 warning: unpack_rsc_op_failure:        Processing failed start of
prm_idredir_test on h02: invalid parameter | rc=2

(Start was not even tried)

Eventually I was able to start the resource. Some other process had a socket
address in use my resource needed...

Regards,
Ulrich
