Hi, Andrew
I read the code.
In the present processing, a setup of "startup-fencing" is read only
once after starting.
https://github.com/ClusterLabs/pacemaker/blob/master/lib/pengine/unpack.c#L455
In Pacemaker-1.0, whenever unpack_nodes() was called, a setup was read.
https://github.com/ClusterLabs/pacemaker-1.0/blob/master/lib/pengine/unpack.c#L194
While a cluster starts, a setup of "startup-fencing" cannot be changed.
It seems to it that the function has deteriorated.
I made the correction to this problem below.
https://github.com/ClusterLabs/pacemaker/pull/512
Will it be good in this fix?
Regards,
Yusuke
