HI all, and thanks for your replies.
First, what is TE(engine)? I'll try your suggestions. Just as a side
note, the DC doesn't change even if the node goes to standby
DC does not imply anything about who is running resources
. It's only the resources moving from "Started NodeA" to "Stopped",
to not being listed at all, to showing up again as "Started NodeB",
in some cases fast enough that the intermediary phases are not
visible.
Does the order in the cib file make a difference? Do we have a
situation where resource #2 is not migrated until #1 is ready on the
other side?
maybe, if you set up and ordering constraint telling us to do this
What about the imagined solution with the dependencies?
Many thanks,
Radu Handorean

Hi Dejan,
You can also try crmadmin -S DC_NODE in a loop until it reports
the IDLE state, then check whichever resource you want.
but this is not an atomic operation. You have a gap between
"ohh, now the cluster seems to be idle" and checking if
the ressource is up. Am I wrong?
true. the only way to be sure is to do something like what the TE
does...
connect to the CIB, subscribe to updates and look for a successful
start
action for your resource(s)
Isn't it that the DC goes idle once the tengine finished with the
transition?
one day i should probably write a tool for that
