This is the first time that I'm installing Slurm, so things are not very

You can do it however you like. You asked if there was a good or existing way to

that do the work and manage that, or just have to learn the ins and outs of
running sreport.
I'm not sure what scripts you have in mind above, since as far as I can
see I already have a working solution for what I need (i.e. keep all job
records from different clusters in a single database).
If I read Brian's comments correctly, he's saying that Slurm already has a
well-tested and documented solution for multi-cluster sites: Federated
clusters. You don't HAVE to use the solution that Slurm/SchedMD provides,
but it will be the easy and well tested solution for you.
If you don't want to use federated clusters, you are free to do so. But
then you have to write *your own scripts* to implement your own ideas.
Probably no-one can help you with your ideas, and you will have to develop
everything by yourself from scratch (not an easy task if this is your
first experience with Slurm).
I hope Brian's comments will help you select the best way forward. The
slurm-users list is generally helpful, also to new Slurm users.

But let's say I go for the federated cluster option. I think my question
still holds. Let's say, for clarity, that I have two clusters (CA and
CB) and another machine (DB) where I will store the mysql database. As
far as I can see, in terms of the daemons running in each machine, I can
implement the whole thing in two ways:
option 1)
CA: slurmd, slurmctld (AccountingStorageHost: DB)
CB: slurmd, slurmctld (AccountingStorageHost: DB)
DB: slurmdbd, mysqld
option 2)
CA: slurmd, slurmctld, slurmdbd (StorageHost: DB)
CB: slurmd, slurmctld, slurmdbd (StorageHost: DB)
DB: mysqld
By reading the documentation on multi-cluster and federated clusters I
think option 1) is the preferred way, but I was just trying to
understand why and what are the pros/cons of each option.
