I am sorry for being impatient, but it's a really critical bug (or lack of
knowledge) for me :(
I can't prevent two resources to run on the same host for some reasons. I
thought, ok,
I recall "groups" had some issues, so I completely stopped using that syntax
But I do have proper constraints, I believe, and resources are still got
started on the same host :(
# crm configure show|grep only
colocation only-one-sql -inf: _rsc_set_ ( fs_node00_sql fs_node01_sql )
# cibadmin -Q -o constraints
<rsc_colocation id="only-one-sql" score="-INFINITY">
<resource_set id="only-one-sql-0" sequential="false">
<resource_ref id="fs_node00_sql"/>
<resource_ref id="fs_node01_sql"/>
</resource_set>
</rsc_colocation>
# crm_mon -1rf|grep sql
