Ok. here we are with the commands.
I send attached the output of cibadmin command when the services stop after
the move operation (cibadmin_stop.log) and after the unmove operation that
causes them to restart (cibadmin_restart.log).
Previous message with attachments in zip format seems didn't go to the list,
perhaps.

#crm resource move nfsclient
WARNING: Creating rsc_location constraint 'cli-standby-nfsclient' with a
score of -INFINITY for resource nfsclient on ha2.
    This will prevent nfsclient from running on ha2 until the constraint is
removed using the 'crm_resource -U' command or manually with cibadmin
    This will be the case even if ha2 is the last node in the cluster
    This message can be disabled with -Q
