Hi all,
I agree with both Marcus and Loris.
I am referring to modifying the association basically since when we
first created our associations we had only "user" and "account" and now
we also need to add the "partition".
My understanding from the documentation was that I would be able to
modify the association and add the partition but it seems that this is
not the case.
So I guess we will proceed with my original solution to delete all
associations consisting of "user" and "account" and create new ones
consisting of "user", "account" and "partition".
Regards,
Thekla

Hi all,
an association is a triple (quadruple if you have several clusters)
consisting of "user", "account" and "partition".
So, you need to add a association.
I'm not sure, how the accounting works, if no partition is set. We are
always setting that triple, automatically during first submission to
this triple.
Not all users / account are allowed to use all partitions. This is
checked externally, and if the user is allowed to submit to a
partition with a specific account, we add that triple with sacctmgr.

Dear Thekla,
Disclaimer: Firstly, I find account management in Slurm confusing and
the documentation strangely unenlightening. Secondly, I don't make many
changes to things once users have been set up, so I have very little
experience of actually tweaking the accounting.
Despite my understanding of the documentation that you *can* modify the
partition of a user, I don't think this is actually the case. If I look
at the database, the user table has no column 'partition' whereas the
association table does.
So you might be able to modify the association, but you might also just
have to delete the association and recreate it with the desired
partitions. Or you might have to do something entirely different ...
Maybe people who do understand Slurm's account management can chip in.
Cheers,

Dear Dori,
Thanks for your reply. Unfortunately this does not work either...

Hi Thekla,
When it comes to partitions, I believe you need to specify the
cluster so in your example:
sacctmgr modify user thekla account=ops set partition=gpu where
cluster=YourClusterName
QOS is not tied to a specific cluster but partitions are. That
should work for you.

Subject: [slurm-users] Add partition to existing user association
Dear all,
I was wondering if there is a way to add a partition to an existing
user association.
For example if I have an association of user thekla to an account
ops I can set a qos for the existing association:
sacctmgr modify user thekla account=ops set qos=nosubmit
Modified user associations...
C = cyclamen A = ops U = thekla
However, I cannot set a partition:
sacctmgr modify user thekla account=ops set partition=gpu
Unknown option: partition=gpu
Use keyword 'where' to modify condition
This is not possible?
The only solution I found to that is to delete the association and
create it again with the partition:
sacctmgr del user thekla account=ops
sacctmgr add user thekla account=ops partition=gpu
Thank you,
Thekla
