I'm pretty sure that a single, central slurmdbd service is required for
multiple, federated clusters. I think that's what ties multiple
clusters together into a single "federation".
You mention a problem with squeue, but you don't list the error
messages. Are you sure that all nodes have identical slurm.conf, and
that daemons have been restarted after changes? You may want to consult
my Slurm Wiki at https://wiki.fysik.dtu.dk/niflheim/SLURM for
configuration details.
Caveat: I just heard the talk at the SLUG conference, but I have no
intention of working with federated clusters myself. So I can't help
you. Commercial support from SchedMD is recommended, see

Thank you very much, Ole
I have read this PDF document, but i'm not sure about the configuration.
I guess the two slurmctld should be configured to use the same slurmdbd.
Is it right? Or which is the right way?
Thanks，regards

Federation support was described at the Slurm User Group Meeting last
month. PDFs of the presentations are online at
http://slurm.schedmd.com/publications.html
See the talk: Technical: Federated Cluster Support, Brian Christiansen
and Danny Auble, SchedMD.
Maybe this will help you?
